Patent Application
20190279606
The present invention relates to new and improved methods of and apparatus for helping individuals, groups of individuals, as well as children and businesses alike, to create original music for various applications, without having special knowledge in music theory or practice, as generally required by prior art technologies.
It is very difficult for video and graphics art creators to find the right music for their content within the time, legal, and budgetary constraints that they face. Further, after hours or days searching for the right music, licensing restrictions, non-exclusivity, and inflexible deliverables often frustrate the process of incorporating the music into digital content. In their projects, content creators often use “Commodity Music” which is music that is valued for its functional purpose but, unlike “Artistic Music”, not for the creativity and collaboration that goes into making it.
Currently, the Commodity Music market is $3 billion and growing, due to the increased amount of content that uses Commodity Music being created annually, and the technology-enabled surge in the number of content creators. From freelance video editors, producers, and consumer content creators to advertising and digital branding agencies and other professional content creation companies, there has been an extreme demand for a solution to the problem of music discovery and incorporation in digital media.
Indeed, the use of computers and algorithms to help create and compose music has been pursued by many for decades, but not with any great success. In his 2000 landmark book, “The Algorithmic Composer,” David Cope surveyed the state of the art back in 2000, and described his progress in “algorithmic composition”, as he put it, including his progress developing his interactive music composition system called ALICE (ALgorithmically Integrated Composing Environment).
In this celebrated book, David Cope described how his ALICE system could be used to assist composers in composing and generating new music, in the style of the composer, and extract musical intelligence from prior music that has been composed, to provide a useful level of assistance which composers had not had before. David Cope has advanced his work in this field over the past 15 years, and his impressive body of work provides musicians with many interesting tools for augmenting their capacities to generate music in accordance with their unique styles, based on best efforts to extract musical intelligence from the artist's music compositions. However, such advancements have clearly fallen short of providing any adequate way of enabling non-musicians to automatically compose and generate unique pieces of music capable of meeting the needs and demands of the rapidly growing commodity music market.
Furthermore, over the past few decades, numerous music composition systems have been proposed and/or developed, employing diverse technologies, such as hidden Markov models, generative grammars, transition networks, chaos and self-similarity (fractals), genetic algorithms, cellular automata, neural networks, and artificial intelligence (AI) methods. While many of these systems seek to compose music with computer-algorithmic assistance, some even seem to compose and generate music in an automated manner.
However, the quality of the music produced by such automated music composition systems has been quite poor to find acceptable usage in commercial markets, or consumer markets seeking to add value to media-related products, special events and the like. Consequently, the dream for machines to produce wonderful music has hitherto been unfulfilled, despite the efforts by many to someday realize the same.
Consequently, many compromises have been adopted to make use of computer or machine assisted music composition suitable for use and sale in contemporary markets.
For example, in U.S. Pat. No. 7,754,959 entitled “System and Method of Automatically Creating An Emotional Controlled Soundtrack” by Herberger et al. (assigned to Magix AG) provides a system for enabling a user of digital video editing software to automatically create an emotionally controlled soundtrack that is matched in overall emotion or mood to the scenes in the underlying video work. As disclosed, the user will be able to control the generation of the soundtrack by positioning emotion tags in the video work that correspond to the general mood of each scene. The subsequent soundtrack generation step utilizes these tags to prepare a musical accompaniment to the video work that generally matches its on-screen activities, and which uses a plurality of prerecorded loops (and tracks) each of which has at least one musical style associated therewith. As disclosed, the moods associated with the emotion tags are selected from the group consisting of happy, sad, romantic, excited, scary, tense, frantic, contemplative, angry, nervous, and ecstatic. As disclosed, the styles associated with the plurality of prerecorded music loops are selected from the group consisting of rock, swing, jazz, waltz, disco, Latin, country, gospel, ragtime, calypso, reggae, oriental, rhythm and blues, salsa, hip hop, rap, samba, zydeco, blues and classical.
While the general concept of using emotion tags to score frames of media is compelling, the automated methods and apparatus for composing and generating pieces of music, as disclosed and taught by Herberger et al. in U.S. Pat. No. 7,754,959, is neither desirable or feasible in most environments and makes this system too limited for useful application in almost any commodity music market.
At the same time, there are a number of companies who are attempting to meet the needs of the rapidly growing commodity music market, albeit, without much success.
In particular, Score Music Interactive (trading as Xhail) based in Market Square, Gorey, in Wexford County, Ireland provides the XHail system which allows users to create novel combinations of prerecorded audio loops and tracks, along the lines proposed in U.S. Pat. No. 7,754,959.
Currently available as beta web-based software, the XHail system allows musically literate individuals to create unique combinations of pre-existing music loops, based on descriptive tags. To reasonably use the XHail system, a user must understand the music creation process, which includes, but is not limited to, (i) knowing what instruments work well when played together, (ii) knowing how the audio levels of instruments should be balanced with each other, (iii) knowing how to craft a musical contour with a diverse palette of instruments, (iv) knowing how to identifying each possible instrument or sound and audio generator, which includes, but is not limited to, orchestral and synthesized instruments, sound effects, and sound wave generators, and (v) possessing standard or average level of knowledge in the field of music.
While the XHail system seems to combine pre-existing music loops into internally-novel combinations at an abrupt pace, much time and effort is required in order to modify the generated combination of pre-existing music loops into an elegant piece of music. Additional time and effort is required to sync the music combination to a pre-existing video. As the XHail system uses pre-created “music loops” as the raw material for its combination process, it is limited by the quantity of loops in its system database and by the quality of each independently created music loop. Further, as the ownership, copyright, and other legal designators of original creativity of each loop are at least partially held by the independent creators of each loop, and because XHail does not control and create the entire creation process, users of the XHail system have legal and financial obligations to each of its loop creators each time a pre-exiting loop is used in a combination.
While the XHail system appears to be a possible solution to music discovery and incorporation, for those looking to replace a composer in the content creation process, it is believed that those desiring to create Artistic Music will always find an artist to create it and will not forfeit the creative power of a human artist to a machine, no matter how capable it may be. Further, the licensing process for the created music is complex, the delivery materials are inflexible, an understanding of music theory and current music software is required for full understanding and use of the system, and perhaps most importantly, the XHail system has no capacity to learn and improve on a user-specific and/or user-wide basis.
The Scorify System by Jukedeck based in London, England, and founded by Cambridge graduates Ed Rex and Patrick Stobbs, uses artificial intelligence (AI) to generate unique, copyright-free pieces of music for everything from YouTube videos to games and lifts. The Scorify system allows video creators to add computer-generated music to their video. The Scorify System is limited in the length of pre-created video that can be used with its system. Scorify's only user inputs are basic style/genre criteria. Currently, Scorify's available styles are: Techno, Jazz, Blues, 8-Bit, and Simple, with optional sub-style instrument designation, and general music tempo guidance. By requiring users to select specific instruments and tempo designations, the Scorify system inherently requires its users to understand classical music terminology and be able to identify each possible instrument or sound and audio generator, which includes, but is not limited to, orchestral and synthesized instruments, sound effects, and sound wave generators.
The Scorify system lacks adequate provisions that allow any user to communicate his or her desires and/or intentions, regarding the piece of music to be created by the system. Further, the audio quality of the individual instruments supported by the Scorify system remains well below professional standards.
Further, the Scorify system does not allow a user to create music independently of a video, to create music for any media other than a video, and to save or access the music created with a video independently of the content with which it was created.
While the Scorify system appears to provide an extremely elementary and limited solution to the market's problem, the system has no capacity for learning and improving on a user-specific and/or user-wide basis. Also, the Scorify system and music delivery mechanism is insufficient to allow creators to create content that accurately reflects their desires and there is no way to edit or improve the created music, either manually or automatically, once it exists.
The SonicFire Pro system by SmartSound out of Beaufort, S.C., USA allows users to purchase and use pre-created music for their video content. Currently available as a web-based and desktop-based application, the SonicFire Pro System provides a Stock Music Library that uses pre-created music, with limited customizability options for its users. By requiring users to select specific instruments and volume designations, the SonicFire Pro system inherently requires its users to have the capacity to (i) identify each possible instrument or sound and audio generator, which includes, but is not limited to, orchestral and synthesized instruments, sound effects, and sound wave generators, and (ii) possess professional knowledge of how each individual instrument should be balanced with every other instrument in the piece. As the music is pre-created, there are limited “Variations” options to each piece of music. Further, because each piece of music is not created organically (i.e. on a note-by-note and/or chord/by-chord basis) for each user, there is a finite amount of music offered to a user. The process is relatively arduous and takes a significant amount of time in selecting a pre-created piece of music, adding limited-customizability features, and then designating the length of the piece of music.
The SonicFire Pro system appears to provide a solution to the market, limited by the amount of content that can be created, and a floor below which the price which the previously-created music cannot go for economic sustenance reasons. Further, with a limited supply of content, the music for each user lacks uniqueness and complete customizability. The SonicFire Pro system does not have any capacity for self-learning or improving on a user-specific and/or user-wide basis. Moreover, the process of using the software to discover and incorporate previously created music can take a significant amount of time, and the resulting discovered music remains limited by stringent licensing and legal requirements, which are likely to be created by using previously-created music.
Stock Music Libraries are collections of pre-created music, often available online, that are available for license. In these Music Libraries, pre-created music is usually tagged with relevant descriptors to allow users to search for a piece of music by keyword. Most glaringly, all stock music (sometimes referred to as “Royalty Free Music”) is pre-created and lacks any user input into the creation of the music. Users must browse what can be hundreds and thousands of individual audio tracks before finding the appropriate piece of music for their content.
Additional examples of stock music containing and exhibiting very similar characteristics, capabilities, limitations, shortcomings, and drawbacks of SmartSound's SonicFire Pro System, include, for example, Audio Socket, Free Music Archive, Friendly Music, Rumble Fish, and Music Bed.
The prior art described above addresses the market need for Commodity Music only partially, as the length of time to discover the right music, the licensing process and cost to incorporate the music into content, and the inflexible delivery options (often a single stereo audio file) serve as a woefully inadequate solution.
Further, the requirement of a certain level of music theory background and/or education adds a layer of training necessary for any content creator to use the current systems to their full potential.
Moreover, the prior art systems described above are static systems that do not learn, adapt, and self-improve as they are used by others, and do not come close to offering “white glove” service comparable to that of the experience of working with a professional composer.
In view, therefore, of the prior art and its shortcomings and drawbacks, there is a great need in the art for a new and improved information processing systems and methods that enable individuals, as well as other information systems, without possessing any musical knowledge, theory or expertise, to automatically compose and generate music pieces for use in scoring diverse kinds of media products, as well as supporting and/or celebrating events, organizations, brands, families and the like as the occasion may suggest or require, while overcoming the shortcomings and drawbacks of prior art systems, methods and technologies.

Referring to the accompanying Drawings, like structures and elements shown throughout the figures thereof shall be indicated with like reference numerals.
The architecture of the automated music composition and generation system of the present invention is inspired by the inventor's real-world experience composing music scores for diverse kinds of media including movies, video-games and the like. As illustrated in
As shown in
The automated music composition and generation system is a complex system comprised of many subsystems, wherein complex calculators, analyzers and other specialized machinery is used to support highly specialized generative processes that support the automated music composition and generation process of the present invention. Each of these components serves a vital role in a specific part of the music composition and generation engine system (i.e. engine) of the present invention, and the combination of each component into a ballet of integral elements in the automated music composition and generation engine creates a value that is truly greater that the sum of any or all of its parts. A concise and detailed technical description of the structure and functional purpose of each of these subsystem components is provided hereinafter in

As shown in FIGS. 27B1 and 27B2, the Descriptor Parameter Capture Subsystem B1 interfaces with a Parameter Transformation Engine Subsystem B51 schematically illustrated in FIG. 27B3B, wherein the musical experience descriptors (e.g. emotion-type descriptors illustrated in
The principles by which such non-musical system user parameters are transformed or otherwise mapped into the probabilistic-based system operating parameters of the various system operating parameter (SOP) tables employed in the system will be described hereinbelow with reference to the transformation engine model schematically illustrated in FIGS. 27B3A, 27B3B and 27B3C, and related figures disclosed herein. In connection therewith, it will be helpful to illustrate how the load of parameter transformation engine in subsystem B51 will increase depending on the degrees of freedom supported by the musical experience descriptor interface in subsystem B0.
Consider an exemplary system where the system supports a set of N different emotion-type musical experience descriptors (Ne) and a set of M different style-type musical experience descriptors (Ms), from which a system user can select at the system user interface subsystem B0. Also, consider the case where the system user is free to select only one emotion-type descriptor from the set of N different emotion-type musical experience descriptors (Ne), and only one style-type descriptor set of M different style-type musical experience descriptors (Ms). In this highly limited case, where the system user can select any one of N unique emotion-type musical experience descriptors (Ne). and only one of the M different style-type musical experience descriptors (Ms), the Parameter Transformation Engine Subsystem B51 FIGS. 27B3A, 27B3B and 27B3C will need to generate Msopt=Ne!/(Ne−r)!re!×Ms!/(Ms−rs)!rs! unique sets of probabilistic system operating parameter (SOP) tables, as illustrated in
For the case where the system user is free to select up to two (2) unique emotion-type musical experience descriptors from the set of N unique emotion-type musical experience descriptors (Ne), and two (2) unique style-type musical experience descriptors from the set of M different style-type musical experience descriptors (Ms), then the Transformation Engine of FIGS. 27B3A, 27B3B and 27B3C must generate Nsopt=Ne!/(Ne−2)!2!×Ms!/(Ms−2)!2! different sets of probabilistic system operating parameter tables (SOPT) as illustrated in
While the quantitative nature of the probabilistic system operating tables have been explored above, particularly with respect to the expected size of the table sets, that can be generated by the Transformation Engine Subsystem B51, it will be appropriate to discuss at a later juncture with reference to FIGS. 27B3A, 27B3B and 27B3C and

It should be noted at this juncture that while the fourth illustrative embodiment shows a fixed set of emotion-type musical experience descriptors, for characterizing the emotional quality of music to be composed and generated by the system of the present invention, it is understood that in general, the music composition system of the present invention can be readily adapted to support the selection and input of a wide variety of emotion-type descriptors such as, for example, linguistic descriptors (e.g. words), images, and/or like representations of emotions, adjectives, or other descriptors that the user would like to music to convey the quality of emotions to be expressed in the music to be composed and generated by the system of the present invention.
At this stage of the workflow, the system user can select COMPOSE and the system will automatically compose and generate music based only on the emotion-type musical experience parameters provided by the system user to the system interface. In such a case, the system will choose the style-type parameters for use during the automated music composition and generation system. Alternatively, the system user has the option to select CANCEL, to allow the user to edit their selections and add music style parameters to the music composition specification.

At this stage, it is appropriate to discuss a few important definitions and terms relating to important music-theoretic concepts that will be helpful to understand when practicing the various embodiments of the automated music composition and generation systems of the present invention. However, it should be noted that, while the system of the present invention has a very complex and rich system architecture, such features and aspects are essentially transparent to all system users, allowing them to have essentially no knowledge of music theory, and no musical experience and/or talent. To use the system of the present invention, all that is required by the system user is to have (i) a sense of what kind of emotions they system user wishes to convey in an automatically composed piece of music, and/or (ii) a sense of what musical style they wish or think the musical composition should follow.
At the top level, the “Pitch Landscape” C0 is a term that encompasses, within a piece of music, the arrangement in space of all events. These events are often, though not always, organized at a high level by the musical piece's key and tonality; at a middle level by the musical piece's structure, form, and phrase; and at a low level by the specific organization of events of each instrument, participant, and/or other component of the musical piece. The various subsystem resources available within the system to support pitch landscape management are indicated in the schematic representation shown in
Similarly, “Rhythmic Landscape” C1 is a term that encompasses, within a piece of music, the arrangement in time of all events. These events are often, though not always, organized at a high level by the musical piece's tempo, meter, and length; at a middle level by the musical piece's structure, form, and phrase; and at a low level by the specific organization of events of each instrument, participant, and/or other component of the musical piece. The various subsystem resources available within the system to support pitch landscape management are indicated in the schematic representation shown in
There are several other high-level concepts that play important roles within the Pitch and Rhythmic Landscape Subsystem Architecture employed in the Automated Music Composition And Generation System of the present invention.
In particular, “Melody Pitch” is a term that encompasses, within a piece of music, the arrangement in space of all events that, either independently or in concert with other events, constitute a melody and/or part of any melodic material of a musical piece being composed.
“Melody Rhythm” is a term that encompasses, within a piece of music, the arrangement in time of all events that, either independently or in concert with other events, constitute a melody and/or part of any melodic material of a musical piece being composed.
“Orchestration” for the piece of music being composed is a term used to describe manipulating, arranging, and/or adapting a piece of music.
“Controller Code” for the piece of music being composed is a term used to describe information related to musical expression, often separate from the actual notes, rhythms, and instrumentation.
“Digital Piece” of music being composed is a term used to describe the representation of a musical piece in a digital or combination or digital and analog, but not solely analog manner.

Specification of Lower (B) Level Subsystems Implementing Higher (A) Level Subsystems with the Automated Music Composition and Generation Systems of the Present Invention, and Quick Identification of Parameter Tables Employed in Each B-Level Subsystem
Referring to FIGS. 23B3A, 27B3B and 27B3C, there is shown a schematic representation illustrating how system user supplied sets of emotion, style and timing/spatial parameters are mapped, via the Parameter Transformation Engine Subsystem B51, into sets of system operating parameters stored in parameter tables that are loaded within respective subsystems across the system of the present invention. Also, the schematic representation illustrated in FIGS. 27B4A, 27B4B, 27B4C, 27B4D and 27B4E, also provides a map that illustrates which lower B-level subsystems are used to implement particular higher A-level subsystems within the system architecture, and which parameter tables are employed within which B-level subsystems within the system. These subsystems and parameter tables will be specified in greater technical detail hereinafter.

The probability-based system operating parameters (SOPs) maintained within the programmed tables of the various subsystems specified in
Specification of the Tempo Generation Table within the Tempo Generation Subsystem (B3)
The primary function of the tempo generation table is to provide a framework to determine the tempo(s) of a musical piece, section, phrase, or other structure. The tempo generation table is used by loading a proper set of parameters into the various subsystems determined by subsystems B1, B37, B40, and B41 and, through a guided stochastic process illustrated in
Specification of the Length Generation Table within the Length Generation Subsystem (B2)
The primary function of the length generation table is to provide a framework to determine the length(s) of a musical piece, section, phrase, or other structure. The length generation table is used by loading a proper set of parameters into the various subsystems determined by subsystems B1, B37, B40, and B41 and, through a guided stochastic process illustrated in
Specification of the Meter Generation Table within the Meter Generation Subsystem (B4)
The primary function of the meter generation table is to provide a framework to determine the meter(s) of a musical piece, section, phrase, or other structure. The meter generation table is used by loading a proper set of parameters into the various subsystems determined by subsystems B1, B37, B40, and B41 and, through a guided stochastic process illustrated in
Like all system operating parameter (SOP) tables, the Parameter Transformation Engine Subsystem B51 generates probability-weighted tempo parameter tables for all of the possible musical experience descriptors selected at the system user input subsystem B0. Taking into consideration these inputs, this subsystem B4 creates the meter(s) of the piece. For example, a piece with an input descriptor of “Happy,” a length of thirty seconds, and a tempo of sixty beats per minute might have a one third probability of using a meter of 4/4 (four quarter notes per measure), a one third probability of using a meter of 6/8 (six eighth notes per measure), and a one third probability of using a tempo of 2/4 (two quarter notes per measure). If there are multiple sections, music timing parameters, and/or starts and stops in the music, multiple meters might be selected.
There is a strong relationship between Emotion and style descriptors and meter. For example, a waltz is often played with a meter of ¾, whereas a march is often played with a meter of 2/4. The system's meter tables are reflections of the cultural connection between a musical experience and/or style and the meter in which the material is delivered.
Further, meter(s) of the musical piece may be unrelated to the emotion and style descriptor inputs and solely in existence to line up the measures and/or beats of the music with certain timing requests. For example, if a piece of music a certain tempo needs to accent a moment in the piece that would otherwise occur on halfway between the fourth beat of a 4/4 measure and the first beat of the next 4/4 measure, an change in the meter of a single measure preceding the desired accent to ⅞ would cause the accent to occur squarely on the first beat of the measure instead, which would then lend itself to a more musical accent in line with the downbeat of the measure.

Methods of Distributing Probability-Based System Operating Parameters (SOP) to the Subsystems within the Automated Music Composition and Generation System of the Present Invention
There are different methods by which the probability-based music-theoretic parameters, generated by the Parameter Transformation Engine Subsystem B51, can be transported to and accessed within the respective subsystems of the automated music composition and generation system of the present invention during the automated music composition process supported thereby. Several different methods will be described in detail below.
According to a first preferred method, described throughout the illustrative embodiments of the present invention, the following operations occur in an organized manner:
(i) the system user provides a set of emotion and style type musical experience descriptors (e.g. HAPPY and POP) and timing/spatial parameters (t=32 seconds) to the system input subsystem B0, which are then transported to the Parameter Transformation Engine Subsystem B51;
(ii) the Parameter Transformation Engine Subsystem B51 automatically generates only those sets of probability-based parameter tables corresponding to HAPPY emotion descriptors, and POP style descriptors, and organizes these music-theoretic parameters in their respective emotion/style-specific parameter tables (or other data suitable structures, such as lists, arrays, etc.); and
(iii) any one or more of the subsystems B1, B37 and B51 are used to transport the probability-based emotion/style-specific parameter tables from Subsystem B51, to their destination subsystems, where these emotion/style-specific parameter tables are loaded into the subsystem, for access and use at particular times/stages in the execution cycle of the automated music composition process of the present invention, according to the timing control process described in
Using this first method, there is no need for the emotion and style type musical experience parameters to be transported to each of numerous subsystems employing probabilistic-based parameter tables. The reason is because the subsystems are loaded with emotion/style-specific parameter tables containing music-theoretic parameter values seeking to implement the musical experience desired by the system user and characterized by the emotion-type and style-type musical experience descriptors selected by the system user and supplied to the system interface. So in this method, the system user's musical experience descriptors need not be transmitted past the Parameter Transformation Engine Subsystem B51, because the music-theoretic parameter tables generated from this subsystem B51 inherently contain the emotion and style type musical experience descriptors selected by the system user. There will be a need to transmit timing/spatial parameters from the system user to particular subsystems by way of the Timing Parameter Capture Subsystem B40, as illustrated throughout the drawings.
According to a second preferred method, the following operations will occur in an organized manner:
(iii) during system configuration and set-up, the Parameter Transformation Engine Subsystem B51 is used to automatically generate all possible (i.e. allowable) sets of probability-based parameter tables corresponding to all of the emotion descriptors and style descriptors available for selection by the system user at the GUI-based Input Output Subsystem B0, and then organizes these music-theoretic parameters in their respective emotion/style parameter tables (or other data suitable structures, such as lists, arrays, etc.);
(ii) during system configuration and set-up, subsystems B1, B37 and B51) are used to transport all sets of generalized probability-based parameter tables across the system data buses to their respective destination subsystems where they are loaded in memory;
(iii) during system operation and use, the system user provides a particular set of emotion and style type musical experience descriptors (e.g. HAPPY and POP) and timing/spatial parameters (t=32 seconds) to the system input subsystem B0, which are then are received by the Parameter Capture Subsystems B1, B37 and B40;
(iv) during system operation and use, the Parameter Capture subsystems B1, B37 and B40 transport these emotion descriptors and style descriptors (selected by the system user) to the various subsystems in the system; and
(v) during system operation and use, the emotion descriptors and style descriptors transmitted to the subsystems are then used by each subsystem to access specific parts of the generalized probabilistic-based parameter tables relating only to the selected emotion and style descriptors (e.g. HAPPY and POP) for access and use at particular times/stages in the execution cycle of the automated music composition process of the present invention, according to the timing control process described in
Using this second method, there is a need for the emotion and style type musical experience parameters to be transported to each of numerous subsystems employing probabilistic-based parameter tables. The reason is because the subsystems need to have information on which emotion/style-specific parameter tables containing music-theoretic parameter values, should be accessed and used during the automated music composition process within the subsystem. So in this second method, the system user's emotion and style musical experience descriptors must be transmitted through Parameter Capture Subsystems B1 and B37 to the various subsystems in the system, because the generalized music-theoretic parameter tables do not contain the emotion and style type musical experience descriptors selected by the system user. Also when using this second method, there will be a need to transmit timing/spatial parameters from the system user to particular subsystems by way of the Timing Parameter Capture Subsystem B40, as illustrated throughout the drawings.
While the above-described methods are preferred, it is understood that other methods can be used to practice the automated system and method for automatically composing and generating music in accordance with the spirit of the present invention.
Specification of the B-Level Subsystems Employed in the Automated Music Composition System of the Present Invention, and the Specific Information Processing Operations Supported by and Performed within Each Subsystem During the Execution of the Automated Music Composition and Generation Process of the Present Invention
A more detail technical specification of each B-level subsystem employed in the system (S) and its Engine (E1) of the present invention, and the specific information processing operations and functions supported by each subsystem during each full cycle of the automated music composition and generation process hereof, will now be described with reference to the schematic illustrations set forth in
Notably, the description of the each subsystem and the operations performed during the automated music composition process will be given by considering an example of where the system generates a complete piece of music, on a note-by-note, chord-by-chord basis, using the automated virtual-instrument music synthesis method, in response to the system user providing the following system inputs: (i) emotion-type music descriptor=HAPPY; (ii) style-type descriptor=POP; and (iii) the timing parameter t=32 seconds.
As shown in the Drawings, the exemplary automated music composition and generation process begins at the Length Generation Subsystem B2 shown in
Also, while Subsystems B1, B37, B40 and B41 do not contribute to generation of musical events during the automated musical composition process, these subsystems perform essential functions involving the collection, management and distribution of emotion, style and timing/spatial parameters captured from system users, and then supplied to the Parameter Transformation Engine Subsystem B51 in a user-transparent manner, where these supplied sets of musical experience and timing/spatial parameters are automatically transformed and mapped into corresponding sets of music-theoretic system operating parameters organized in tables, or other suitable data/information structures that are distributed and loaded into their respective subsystems, under the control of the Subsystem Control Subsystem B60, illustrated in
FIGS. 27B1 and 27B2 show a schematic representation of the (Emotion-Type) Descriptor Parameter Capture Subsystem (B1) used in the Automated Music Composition and Generation Engine of the present invention. The Descriptor Parameter Capture Subsystem B1 serves as an input mechanism that allows the user to designate his or her preferred emotion, sentiment, and/or other descriptor for the music. It is an interactive subsystem of which the user has creative control, set within the boundaries of the subsystem.
In the illustrative example, the system user provides the exemplary “emotion-type” musical experience descriptor—HAPPY—to the descriptor parameter capture subsystem B1. These parameters are used by the parameter transformation engine B51 to generate probability-based parameter programming tables for subsequent distribution to the various subsystems therein, and also subsequent subsystem set up and use during the automated music composition and generation process of the present invention.
Once the parameters are inputted, the Parameter Transformation Engine Subsystem B51 generates the system operating parameter tables and then the subsystem 51 loads the relevant data tables, data sets, and other information into each of the other subsystems across the system. The emotion-type descriptor parameters can be inputted to subsystem B51 either manually or semi-automatically by a system user, or automatically by the subsystem itself. In processing the input parameters, the subsystem 51 may distill (i.e. parse and transform) the emotion descriptor parameters to any combination of descriptors as described in
Preferably, the number of distilled descriptors is between one and ten, but the number can and will vary from embodiment to embodiment, from application to application. If there are multiple distilled descriptors, and as necessary, the Parameter Transformation Engine Subsystem B51 can create new parameter data tables, data sets, and other information by combining previously existing data tables, data sets, and other information to accurately represent the inputted descriptor parameters. For example, the descriptor parameter “happy” might load parameter data sets related to a major key and an upbeat tempo. This transformation and mapping process will be described in greater detail with reference to the Parameter Transformation Engine Subsystem B51 described in greater detail hereinbelow.
In addition to performing the music-theoretic and information processing functions specified above, when necessary or helpful, System B1 can also assist the Parameter Transformation Engine System B51 in transporting probability-based music-theoretic system operating parameter (SOP) tables (or like data structures) to the various subsystems deployed throughout the automated music composition and generation system of the present invention.
FIGS. 27C1 and 27C2 show a schematic representation of the Style Parameter Capture Subsystem (B37) used in the Automated Music Composition and Generation Engine and System of the present invention. The Style Parameter Capture Subsystem B37 serves as an input mechanism that allows the user to designate his or her preferred style parameter(s) of the musical piece. It is an interactive subsystem of which the user has creative control, set within the boundaries of the subsystem. This information is based on either user inputs (if given), computationally-determined value(s), or a combination of both. Style, or the characteristic manner of presentation of musical elements (melody, rhythm, harmony, dynamics, form, etc.), is a fundamental building block of any musical piece. In the illustrative example of FIGS. 27C1 and 27C2, the probability-based parameter programming table employed in the subsystem is set up for the exemplary “style-type” musical experience descriptor=POP and used during the automated music composition and generation process of the present invention.
The style descriptor parameters can be inputted manually or semi-automatically or by a system user, or automatically by the subsystem itself. Once the parameters are inputted, the Parameter Transformation Engine Subsystem B51 receives the user's musical style inputs from B37 and generates the relevant probability tables across the rest of the system, typically by analyzing the sets of tables that do exist and referring to the currently provided style descriptors. If multiple descriptors are requested, the Parameter Transformation Engine Subsystem B51 generates system operating parameter (SOP) tables that reflect the combination of style descriptors provided, and then subsystem B37 loads these parameter tables into their respective subsystems.
In processing the input parameters, the Parameter Transformation Engine Subsystem B51 may distill the input parameters to any combination of styles as described in
In addition to performing the music-theoretic and information processing functions specified above, when necessary or helpful, Subsystem B37 can also assist the Parameter Transformation Engine System B51 in transporting probability-based music-theoretic system operating parameter (SOP) tables (or like data structures) to the various subsystems deployed throughout the automated music composition and generation system of the present invention.
In addition to performing the music-theoretic and information processing functions specified above, when necessary or helpful, Subsystem B40 can also assist the Parameter Transformation Engine System B51 in transporting probability-based music-theoretic system operating parameter (SOP) tables (or like data structures) to the various subsystems deployed throughout the automated music composition and generation system of the present invention.
As illustrated in FIGS. 27B3A, 27B3B and 27B3C, the Parameter Transformation Engine Subsystem B51 is shown integrated with subsystems B1, B37 and B40 for handling emotion-type, style-type and timing-type parameters, respectively, supplied by the system user though subsystem B0. The Parameter Transformation Engine Subsystem B51 performs an essential function by accepting the system user input(s) descriptors and parameters from subsystems B1, B37 and B40, and transforming these parameters (e.g. input(s)) into the probability-based system operating parameter tables that the system will use during its operations to automatically compose and generate music using the virtual-instrument music synthesis technique disclosed herein. The programmed methods used by the parameter transformation engine subsystem (B51) to process any set of musical experience (e.g. emotion and style) descriptors and timing and/or spatial parameters, for use in creating a piece of unique music, will be described in great detail hereinafter with reference to FIGS. 27B3A through 27B3C, wherein the musical experience descriptors (e.g. emotion and style descriptors) and timing and spatial parameters that are selected from the available menus at the system user interface of input subsystem B0 are automatically transformed into corresponding sets of probabilistic-based system operating parameter (SOP) tables which are loaded into and used within respective subsystems in the system during the music composition and generation process.
As will be explained in greater detail below, this parameter transformation process supported within Subsystem B51 employs music theoretic concepts that are expressed and embodied within the probabilistic-based system operation parameter (SOP) tables maintained within the subsystems of the system, and controls the operation thereof during the execution of the time-sequential process controlled by the timing signals illustrated in timing control diagram set forth in
In addition to performing the music-theoretic and information processing functions specified above, the Parameter Transformation Engine System B51 is fully capable of transporting probability-based music-theoretic system operating parameter (SOP) tables (or like data structures) to the various subsystems deployed throughout the automated music composition and generation system of the present invention.
In general, there is a need with the system to manage multiple emotion-type and style-type musical experience descriptors selected by the system user, to produce corresponding sets of probability-based music-theoretic parameters for use within the subsystems of the system of the present invention. The primary function of the Parameter Table Handling and Processing Subsystem B70 is to address this need at either a global or local level, as described in detail below.
FIG. 27B5 shows the Parameter Table Handling and Processing Subsystem (B70) used in connection with the Automated Music Composition and Generation Engine of the present invention. The primary function of the Parameter Table Handling and Processing Subsystem (B70) is to determine if any system parameter table transformation(s) are required in order to produce system parameter tables in a form that is more convenient and easier to process and use within the subsystems of the system of the present invention. The Parameter Table Handling and Processing Subsystem (B70) performs its functions by (i) receiving multiple (i.e. one or more) emotion/style-specific music-theoretic system operating parameter (SOP) tables from the data output port of the Parameter Transformation Engine Subsystem B51, (ii) processing these parameter tables using one or parameter table processing methods M1, M2 or M3, described below, and (iii) generating system operating parameter tables in a form that is more convenient and easier to process and use within the subsystems of the system of the present invention.
In general, there are two different ways in which to practice this aspect of the present invention: (i) performing parameter table handing and transformation processing operations in a global manner, as shown with the Parameter Table Handling and Processing Subsystem B70 configured with the Parameter Transformation Engine Subsystem B51, as shown in
As shown in
As shown in FIG. 27B5, the Parameter Table Handling and Processing Subsystem B70 receives one or more emotion/style-indexed system operating parameter tables and determines whether or not system input (i.e. parameter table) transformation is required, or not required, as the case may be. In the event only a single emotion/style-indexed system parameter table is received, it is unlikely transformation will be required and therefore the system parameter table is typically transmitted to the data output port of the subsystem B70 in a pass-through manner. In the event that two or more emotion/style-indexed system parameter tables are received, then it is likely that these parameter tables will require or benefit from transformation processing, so the subsystem B70 supports three different methods M1, M2 and M3 for operating on the system parameter tables received at its data input ports, to transform these parameter tables into parameter table that are in a form that is more suitable for optimal use within the subsystems.
There are three case scenarios to consider and accompanying rules to use in situations where multiple emotion/style musical experience descriptors are provided to the input subsystem B0, and multiple emotion/style-indexed system parameter tables are automatically generated by the Parameter Transformation Engine Subsystem B51.
Considering the first case scenario, where Method M1 is employed, the subsystem B70 makes a determination among the multiple emotion/style-indexed system parameter tables, and decides to use only one of the emotion/style-indexed system parameter tables. In scenario Method 1, the subsystem B70 recognizes that, either in a specific instance or as an overall trend, that among the multiple parameter tables generated in response to multiple musical experience descriptors inputted into the subsystem B0, a single one of these descriptors-indexed parameter tables might be best utilized.
As an example, if HAPPY, EXHUBERANT, and POSITIVE were all inputted as emotion-type musical experience descriptors, then the system parameter table(s) generated for EXHUBERANT might likely provide the necessary musical framework to respond to all three inputs because EXUBERANT encompassed HAPPY and POSITIVE. Additionally, if CHRISTMAS, HOLIDAY, AND WINTER were all inputted as style-type musical experience descriptors, then the table(s) for CHRISTMAS might likely provide the necessary musical framework to respond to all three inputs.
Further, if EXCITING and NERVOUSNESS were both inputted as emotion-type musical experience descriptors and if the system user specified EXCITING: 9 out of 10, where 10 is maximum excitement and 0 is minimum excitement and NERVOUSNESS: 2 out of 10, where 10 is maximum NERVOUSNESS and 0 is minimum NERVOUSNESS (whereby the amount of each descriptor might be conveyed graphically by, but not limited to, moving a slider on a line or by entering in a percentage into a text field), then the system parameter table(s) for EXCITING might likely provide the necessary musical framework to respond to both inputs. In all three of these examples, the musical experience descriptor that is a subset and, thus, a more specific version of the additional descriptors, is selected as the musical experience descriptor whose table(s) might be used.
Considering the second case scenario, where Method M2 is employed, the subsystem B70 makes a determination among the multiple emotion/style-indexed system parameter tables, and decides to use a combination of the multiple emotion/style descriptor-indexed system parameter tables.
In scenario Method 2, the subsystem B70 recognizes that, either in a specific instance or as an overall trend, that among the multiple emotion/style descriptor indexed system parameter tables generated by subsystem B51 in response to multiple emotion/style descriptor inputted into the subsystem BO, a combination of some or all of these descriptor-indexed system parameter tables might best be utilized. According to Method M2, this combination of system parameter tables might be created by employing functions including, but not limited to, (weighted) average(s) and dominance of a specific descriptor's table(s) in a specific table only.
As an example, if HAPPY, EXUBERANT, AND POSITIVE were all inputted as emotional descriptors, the system parameter table(s) for all three descriptors might likely work well together to provide the necessary musical framework to respond to all three inputs by averaging the data in each subsystem table (with equal weighting). Additionally, IF CHRISTMAS, HOLIDAY, and WINTER were all inputted as style descriptors, the table(s) for all three might likely provide the necessary musical framework to respond to all three inputs by using the CHRISTMAS tables for the General Rhythm Generation Subsystem A1, the HOLIDAY tables for the General Pitch Generation Subsystem A2, and the a combination of the HOLIDAY and WINTER system parameter tables for the Controller Code and all other subsystems. Further, if EXCITING and NERVOUSNESS were both inputted as emotion-type musical experience descriptors and if the system user specified Exciting: 9 out of 10, where 10 is maximum excitement and 0 is minimum excitement and NERVOUSNESS: 2 out of 10, where 10 is maximum nervousness and 0 is minimum nervousness (whereby the amount of each descriptor might be conveyed graphically by, but not limited to, moving a slider on a line or by entering in a percentage into a text field), the weight in table(s) employing a weighted average might be influenced by the level of the user's specification. In all three of these examples, the descriptors are not categorized as solely a set(s) and subset(s), but also by their relationship within the overall emotional and/or style spectrum to each other.
Considering the third case scenario, where Method M3 is employed, the subsystem B70 makes a determination among the multiple emotion/style-indexed system parameter tables, and decides to use neither of multiple emotion/style descriptor-indexed system parameter tables. In scenario Method 3, the subsystem B70 recognizes that, either in a specific instance or as an overall trend, that among the multiple emotion/style-descriptor indexed system parameter tables generated by subsystem B51 in response to multiple emotion/style descriptor inputted into the subsystem BO, none of the emotion/style-indexed system parameter tables might best be utilized.
As an example, if HAPPY and SAD were both inputted as emotional descriptors, the system might determine that table(s) for a separate descriptor(s), such as BIPOLAR, might likely work well together to provide the necessary musical framework to respond to both inputs. Additionally, if ACOUSTIC, INDIE, and FOLK were all inputted as style descriptors, the system might determine that table(s) for separate descriptor(s), such as PIANO, GUITAR, VIOLIN, and BANJO, might likely work well together to provide the necessary musical framework, possibly following the avenues(s) described in Method 2 above, to respond to the inputs. Further, if EXCITING and NERVOUSNESS were both inputted as emotional descriptors and if the system user specified Exciting: 9 out of 10, where 10 is maximum excitement and 0 is minimum excitement and Nervousness: 8 out of 10, where 10 is maximum nervousness and 0 is minimum nervousness (whereby the amount of each descriptor might be conveyed graphically by, but not limited to, moving a slider on a line or by entering in a percentage into a text field), the system might determine that an appropriate description of these inputs is Panicked and, lacking a pre-existing set of system parameter tables for the descriptor PANICKED, might utilize (possibility similar) existing descriptors' system parameter tables to autonomously create a set of tables for the new descriptor, then using these new system parameter tables in the subsystem(s) process(es).
In all of these examples, the subsystem B70 recognizes that there are, or could be created, additional or alternative descriptor(s) whose corresponding system parameter tables might be used (together) to provide a framework that ultimately creates a musical piece that satisfies the intent(s) of the system user.
FIG. 27B6 shows the Parameter Table Archive Database Subsystem (B80) used in the Automated Music Composition and Generation System of the present invention. The primary function of this subsystem B80 is persistent storing and archiving user account profiles, tastes and preferences, as well as all emotion/style-indexed system operating parameter (SOP) tables generated for individual system users, and populations of system users, who have made music composition requests on the system, and have provided feedback on pieces of music composed by the system in response to emotion/style/timing parameters provided to the system.
As shown in FIG. 27B6, the Parameter Table Archive Database Subsystem B80, realized as a relational database management system (RBMS), non-relational database system or other database technology, stores data in table structures in the illustrative embodiment, according to database schemas, as illustrated in FIG. 27B6.
As shown, the output data port of the GUI-based Input Output Subsystem B0 is connected to the output data port of the Parameter Table Archive Database Subsystem B80 for receiving database requests from system users who use the system GUI interface. As shown, the output data ports of Subsystems B42 through B48 involved in feedback and learning operations, are operably connected to the data input port of the Parameter Table Archive Database Subsystem B80 for sending requests for archived parameter tables, accessing the database to modify database and parameter tables, and performing operations involved system feedback and learning operations. As shown, the data output port of the Parameter Table Archive Database Subsystem B80 is operably connected to the data input ports of the Systems B42 through B48 involved in feedback and learning operations. Also, as shown in
In general, while all parameter data sets, tables and like structures will be stored globally in the Parameter Table Archive Database Subsystem B80, it is understood that the system will also support local persistent data storage within subsystems, as required to support the specialized information processing operations performed therein in a high-speed and reliable manner during automated music composition and generation processes on the system of the present invention.
FIGS. 27E1 and 27E2 shows the Timing Generation Subsystem (B41) used in the Automated Music Composition and Generation Engine of the present invention. In general, the Timing Generation Subsystem B41 determines the timing parameters for the musical piece. This information is based on either user inputs (if given), compute-determined value(s), or a combination of both. Timing parameters, including, but not limited to, or designations for the musical piece to start, stop, modulate, accent, change volume, change form, change melody, change chords, change instrumentation, change orchestration, change meter, change tempo, and/or change descriptor parameters, are a fundamental building block of any musical piece.
The Timing Parameter Capture Subsystem B40 can be viewed as creating a timing map for the piece of music being created, including, but not limited to, the piece's descriptor(s), style(s), descriptor changes, style changes, instrument changes, general timing information (start, pause, hit point, stop), meter (changes), tempo (changes), key (changes), tonality (changes) controller code information, and audio mix. This map can be created entirely by a user, entirely by the Subsystem, or in collaboration between the user and the subsystem.
More particularly, the Timing Parameter Capture Subsystem (B40) provides timing parameters (e.g. piece length) to the Timing Generation Subsystem (B41) for generating timing information relating to (i) the length of the piece to be composed, (ii) start of the music piece, (iii) the stop of the music piece, (iv) increases in volume of the music piece, and (v) any accents in the music piece that are to be created during the automated music composition and generation process of the present invention.
For example, a system user might request that a musical piece begin at a certain point, modulate a few seconds later, change tempo even later, pause, resume, and then end with a large accent. This information is transmitted to the rest of the system's subsystems to allow for accurate and successful implementation of the user requests. There might also be a combination of user and system inputs that allow the piece to be created as successfully as possible, including the scenario when a user might elect a start point for the music, but fail to input to stop point. Without any user input, the system would create a logical and musical stop point. Thirdly, without any user input, the system might create an entire set of timing parameters in an attempt to accurately deliver what it believes the user desires.
In the illustrative embodiment, the Length Generation Subsystem B2 obtains the timing map information from subsystem B41 and determines the length of the musical piece. By default, if the musical piece is being created to accompany any previously existing content, then the length of the musical piece will equal the length of the previously existing content. If a user wants to manually input the desired length, then the user can either insert the desired lengths in any time format, such as [hours: minutes: seconds] format, or can visually input the desired length by placing digital milestones, including, but not limited to, “music start” and “music stop” on a graphically displayed timeline. This process may be replicated or autonomously completed by the subsystem itself. For example, a user using the system interface of the system, may select a point along the graphically displayed timeline to request (i) the “music start,” and (ii) that the music last for thirty seconds, and then request (through the system interface) the subsystem to automatically create the “music stop” milestone at the appropriate time.

The Parameter Transformation Engine Subsystem B51 generates probability-weighted tempo parameter tables for the various musical experience descriptors selected by the system user and provided to the Input Subsystem B0. In
As illustrated in
Taking into consideration the output of the Length Generation Subsystem B2, the Tempo Generation Subsystem creates the tempo(s) of the piece. For example, a piece with an input emotion-type descriptor “Happy”, and a length of thirty seconds, might have a one third probability of using a tempo of sixty beats per minute, a one third probability of using a tempo of eighty beats per minute, and a one third probability of using a tempo of one hundred beats per minute. If there are multiple sections and or starts and stops in the music, then music timing parameters, and/or multiple tempos might be selected, as well as the tempo curve that adjusts the tempo between sections. This curve can last a significant amount of time (for example, many measures) or can last no time at all (for example, an instant change of tempo).
As shown in
The Parameter Transformation Engine Subsystem B51 generates probability-weighted tempo parameter tables for the various musical experience descriptors selected by the system user using the input subsystem B0. In
As shown in
The Parameter Transformation Engine Subsystem B51 generates probability-weighted parameter tables for the various musical experience descriptors selected by the system user using the input subsystem B0. In
As shown in
The Parameter Transformation Engine Subsystem B51 generates probability-weighted key parameter tables for the various musical experience descriptors selected, from the input subsystem B0. In
As shown in
As shown in
As shown in
Each parameter table contains probabilities that sum to 1. Each specific probability contains a specific section of the 0-1 domain. If the random number is within the specific section of a probability, then it is selected. For example, if two parameters, A and B, each have a 50% chance of being selected, then if the random number falls between 0-0.5, it will select A, and if it falls between 0.5-1, it will select B.
The number of tonality of the piece is selected using the probability-based tonality parameter table setup within the subsystem B7. The Parameter Transformation Engine Subsystem B51 generates probability-weighted tonality parameter tables for the various musical experience descriptors selected by the system user and provided to the input subsystem B0. In
Taking into consideration all system user inputs provided to subsystem B0, this system B7 creates the tonality(s) of the piece. For example, a piece with an input descriptor of “Happy,” a length of thirty seconds, a tempo of sixty beats per minute, a meter of 4/4, and a key of C might have a two thirds probability of using a major tonality or a one third probability of using a minor tonality. If there are multiple sections, music timing parameters, and/or starts and stops in the music, then multiple tonalities might be selected. The output of the Tonality Generation Subsystem B7 is the selected tonality of the piece of music being composed. In the example, a “Major scale” tonality is selected in
FIGS. 27M1 and 27M2 show the Song Form Generation Subsystem (B9) used in the Automated Music Composition and Generation Engine of the present invention. Form, or the structure of a musical piece, is a fundamental building block of any musical piece. The Song Form Generation Subsystem determines the song form of a musical piece. This information is based on either user inputs (if given), computationally-determined value(s), or a combination of both.
As shown in FIGS. 27M1 and 27M2, this subsystem is supported by the song form parameter tables and song form sub-phrase tables illustrated in
In general, the song form is selected using the probability-based song form sub-phrase parameter table set up within the subsystem B9. The Parameter Transformation Engine Subsystem B51 generates a probability-weighted song form parameters for the various musical experience descriptors selected by the system user and provided to the Input Subsystem B0. In FIGS. 27M1 and 27M2, probability-based parameter tables employed in the subsystem B9 are set up for the exemplary “emotion-type” musical experience descriptor—HAPPY—and used during the automated music composition and generation process so as to generate a part of the piece of music being composed, as illustrated in the musical score representation illustrated at the bottom of the figure drawing.
Taking into consideration all system user inputs provided to subsystem B0, the subsystem B9 creates the song form of the piece. For example, a piece with an input descriptor of “Happy,” a length of thirty seconds, a tempo of sixty beats per minute, and a meter of 4/4 might have a one third probability of a form of ABA (or alternatively described as Verse Chorus Verse), a one third probability of a form of AAB (or alternatively described as Verse Verse Chorus), or a one third probability of a form of AAA (or alternatively described as Verse Verse Verse). Further each section of the song form may have multiple sub-sections, so that the initial section, A, may be comprised of subsections “aba” (following the same possible probabilities and descriptions described previously). Even further, each sub-section may be have multiple motifs, so that the subsection “a” may be comprised of motifs “i, ii, iii” (following the same possible probabilities and descriptions described previously).
All music has a form, even if the form is empty, unorganized, or absent. Pop music traditionally has form elements including Intro, Verse, Chorus, Bridge, Solo, Outro, etc. Each form element can be represented with a letter to help communicate the overall piece's form in a concise manner, so that a song with form Verse Chorus Verse can also be represented as A B A. Song form phrases can also have sub-phrases that provide structure to a song within the phrase itself. If a verse, or A section, consists of two repeated stanzas, then the sub-phrases might be “aa.”
As shown in FIGS. 27M1 and 27M2, the Song Form Generation Subsystem B9 receives and loads as input, song form tables from subsystem B51. While the song form is selected from the song form table using the random number generator, although it is understood that other lyrical-input based mechanisms might be used in other system embodiments as shown in
As shown in
The Parameter Transformation Engine Subsystem B51 generates a probability-weighted set of sub-phrase length parameter tables for the various musical experience descriptors selected by the system user and provided to the input subsystem B0. In
The Sub-Phrase Length Generation Subsystem (B15) determines the length of the sub-phrases (i.e. rhythmic length) within each phrase of a piece of music being composed. These lengths are determined by (i) the overall length of the phrase (i.e. a phrase of 2 seconds will have many fewer sub-phrase options that a phrase of 200 seconds), (ii) the timing necessities of the piece, and (iii) the emotion-type and style-type musical experience descriptors.
Taking into consideration all system user inputs provided to the subsystem B0, this system B15 creates the sub-phrase lengths of the piece. For example, a 30 second piece of music might have four sub-subsections of 7.5 seconds each, three sub-sections of 10 seconds, or five subsections of 4, 5, 6, 7, and 8 seconds.
For example, as shown in the Sub-Phrase Length Generation Subsystem (B15), the sub-phrase length tables are loaded, and for each sub-phrase in the selected song form, the subsystem B15, in parallel manner, selects length measures for each sub-phrase and then creates a sub-phrase length (i.e. rhythmic length) table as output from the subsystem, as illustrated in the musical score representation set forth at the bottom of
FIGS. 27O1, 27O2, 27O3 and 27O4 show the Chord Length Generation Subsystem (B11) used in the Automated Music Composition and Generation Engine and System of the present invention. Rhythm, or the subdivision of a space of time into a defined, repeatable pattern or the controlled movement of music in time, is a fundamental building block of any musical piece. The Chord Length Generation Subsystem B11 determines rhythm (i.e. default chord length(s)) of each chord in the musical piece. This information is based on either user inputs (if given), computationally-determined value(s), or a combination of both.
As shown in FIGS. 27O1 through 27O4, the Chord Length Generation Subsystem B11 is supported by the chord length parameter tables illustrated in
In general, the chord length is selected using the probability-based chord length parameter table set up within the subsystem based on the musical experience descriptors provided to the system by the system user. The selected chord length is used during the automated music composition and generation process of the present invention so as to generate a part of the piece of music being composed, as illustrated in the musical score representation illustrated at the bottom of FIG. 27O4.
The Parameter Transformation Engine Subsystem B51 generates the probability-weighted set of chord length parameter tables for the various musical experience descriptors selected by the system user and provided to the input subsystem B0. In FIGS. 27O1 through 27O4, probability-based parameter tables employed in the subsystem B11 are set up for the exemplary “emotion-type” musical experience descriptor—HAPPY—and used during the automated music composition and generation process so as to generate a part of the piece of music being composed, as illustrated in the musical score representation illustrated at the bottom of the figure drawing.
The subsystem B11 uses system-user-supplied musical experience descriptors and timing parameters, and the parameter tables loaded to subsystem B11, to create the chord lengths throughout the piece (usually, though not necessarily, in terms of beats and measures). For example, a chord in a 4/4 measure might last for two beats, and based on this information the next chord might last for 1 beat, and based on this information the final chord in the measure might last for 1 beat. The first chord might also last for one beat, and based on this information the next chord might last for 3 beats.
As shown in FIGS. 27O1 through 27O4, the chord length tables shown in

Taking into consideration inputs received from subsystem B1, B31 and/or B40, the subsystem B12 creates the phrase lengths of the piece of music being automatically composed. For example, a one-minute second piece of music might have two phrases of thirty seconds or three phrases of twenty seconds. The lengths of the sub-sections previously created are used to inform the lengths of each phrase, as a combination of one or more sub-sections creates the length of the phrase. The output phrase lengths are graphically illustrated in the music score representation shown in
As shown in
Within the Unique Phrase Generation Subsystem (B10), the Phrase Analyzer analyzes the data supplied from subsystem B12 so as to generate a listing of the number of unique phrases or sections in the piece to be composed. If a one-minute piece of music has four 15 second phrases, then there might be four unique phrases that each occur once, three unique phrases (two of which occur once each and one of which occurs twice), two unique phrases that occur twice each, or one unique phrase that occurs four times, and this data will be produced as output from Subsystem B10.
As shown in
As shown in
The Parameter Transformation Engine Subsystem B51 generates the probability-weighted data set of root notes and chord function (i.e. parameter tables) for the various musical experience descriptors selected by the system user and supplied to the input subsystem B0. In
Subsystem B17 uses parameter tables generated and loaded by subsystem B51 so as to select the initial chord of the piece. For example, in a “Happy” piece of music in C major, there might be a one third probability that the initial chord is a C major triad, a one third probability that the initial chord is a G major triad, and a one third probability that the initial chord is an F major triad.
As shown in
FIGS. 27V1, 27V2 and 27V3 show the Sub-Phrase Chord Progression Generation Subsystem (B19) used in the Automated Music Composition and Generation Engine of the present invention. Chord, or the sounding of two or more notes (usually at least three) simultaneously, is a fundamental building block of any musical piece. The Sub-Phrase Chord Progression Generation Subsystem B19 determines what the chord progression will be for each sub-phrase of the musical piece. This information is based on either user inputs (if given), computationally-determined value(s), or a combination of both.
As shown in 27V1, 27V2 and 27V3, the Sub-Phrase Chord Progression Generation Subsystem B19 is supported by the chord root tables, chord function root modifier tables, the chord root modifier tables, the current function tables, and the beat root modifier table tables shown in FIGS. 28J1 and 28J2, a Beat Analyzer, and a parameter selection mechanism (e.g. random number generator, or lyrical-input based parameter selector). The primary function of the Beat Analyzer is to determine the position in time of a current or future musical event(s). The beat analyze uses the tempo, meter, and form of a piece, section, phrase, or other structure to determine its output.
The Parameter Transformation Engine Subsystem B51 generates the probability-weighted set of sub-phrase chord progression parameter tables for the various musical experience descriptors selected by the system user and supplied to the input subsystem B0. The probability-based parameter tables (i.e. chord root table, chord function root modifier table, and beat root modifier table) employed in the subsystem is set up for the exemplary “emotion-type” musical experience descriptor—HAPPY—and used during the automated music composition and generation process of the present invention.
As shown in FIGS. 27V1 and 27V2, the Subsystem B19 accessed the chord root tables generated and loaded by subsystem B51, and uses a random number generator or suitable parameter selection mechanism to select the initial chord of the piece. For example, in a “Happy” piece of music in C major, with an initial sub-phrase chord of C major, there might be a one third probability that the next chord is a C major triad, a one third probability that the next chord is a G major triad, and a one third probability that the next chord is an F major triad. This model takes into account every possible preceding outcome, and all possible future outcomes, to determine the probabilities of each chord being selected. This process repeats from the beginning of each sub-phrase to the end of each sub-phrase.
As indicated in FIGS. 27V2 and 27V3, the subsystem B19 accesses the chord function modifier table loaded into the subsystem, and adds or subtracts values to the original root note column values in the chord root table.
Then as indicated in FIGS. 27V2 and 27V3, the subsystem B19 accesses the beat root modifier table loaded into the subsystem B19, as shown, and uses the Beat Analyzer to determine the position in time of a current or future musical event(s), by considering the tempo, meter, and form of a piece, section, phrase, or other structure, and then selects a beat root modifier. In the case example, the upcoming beat in the measure equals 2.
The subsystem B19 then adds the beat root modifier table values to or subtracted from the original root note column values in the chord root table.
As shown in FIG. 27V3, using a random number generator, or other parameter selection mechanism, the subsystem B19 selects the next chord root.
Beginning with the chord function root modifier table, the process described above is repeated until all chords have been selected.
As shown in FIG. 27V3, the chords which have been automatically selected by the Sub-Phrase Chord Progression Generation Subsystem B19 are graphically shown on the musical score representation for the piece of music being composed.
As shown in
During operation, Phrase Chord Progression Generation Subsystem B18 receives the output from Initial Chord Generation Subsystem B17 and modifies, changes, adds, and deletes chords from each sub-phrase to generate the chords of each phrase. For example, if a phrase consists of two sub-phrases that each contain an identical chord progression, there might be a one half probability that the first chord in the second sub-phrase is altered to create a more musical chord progression (following a data set or parameter table created and loaded by subsystem B51) for the phrase and a one half probability that the sub-phrase chord progressions remain unchanged.
FIGS. 27X1, 27X2 and 27X3 show the Chord Inversion Generation Subsystem (B20) used in the Automated Music Composition and Generation Engine of the present invention. The Chord Inversion Generation Subsystem B20 determines the inversion of each chord in the musical piece. This information is based on either user inputs (if given), computationally-determined value(s), or a combination of both. Inversion, or the position of notes a chord, is a fundamental building block of any musical piece. Chord inversion is determined using the initial chord inversion table and the chord inversion table.
As shown in FIGS. 27X1 and 27X2, this Subsystem B20 is supported by the initial chord inversion table and the chord inversion table shown in
The Parameter Transformation Engine Subsystem B51 generates the probability-weighted set of chord inversion parameter tables for the various musical experience descriptors selected by the system user and provided to the input subsystem B0. In FIGS. 27X1 through 27X3, the probability-based parameter tables (i.e. initial chord inversion table, and chord inversion table) employed in the subsystem are set up for the exemplary “emotion-type” musical experience descriptor—HAPPY.
As shown in FIGS. 27X1 and 27X2, the Subsystem B20 receives, as input, the output from the Subsystem B19, and accesses the initial chord inversion tables and chord inversion tables shown in
For example, if a C Major triad is in root position (C, E, G) and the next chord is a G Major triad, there might be a one third probability that the G Major triad is in root position, a one third probability that the G Major triad is in the first inversion (E, G, C), or a one third probability that the G Major triad is in the second inversion (G, C, E).
As shown in FIG. 27X3, after the inversion of an initial chord has been determined, the chord inversion selection process is repeated until all chord inversions have been selected. All previous inversion determinations affect all future ones. An upcoming chord inversion in the piece of music, phrase, sub-phrase, and measure affects the default landscape of what chord inversions might be selected in the future.
As shown in FIG. 27X3, the final list of inverted chords are shown graphically displayed in the musical score representation located at the bottom of FIG. 27X3.
As shown in
The Parameter Transformation Engine Subsystem B51 generates the probability-weighted data set of sub-phrase lengths (i.e. parameter tables) for the various musical experience descriptors selected by the system user and provided to the input subsystem B0. In
During operation, subsystem B25 uses, as inputs, all previous unique sub-phrase length outputs, in combination with the melody length parameter tables loaded by subsystem B51 to determine the length of each sub-phrase melody.
As indicated in
As shown in the case example, the output of subsystem B25 is a set of melody length assignments to the musical being composed, namely: the a sub-phrase is assigned a “d” length equal to 6/4; the b sub-phrase is assigned an “e” length equal to 7/4; and the c sub-phrase is assigned an “f” length equal to 6/4.
FIGS. 27Z1 and 27Z2 show the Melody Sub-Phrase Generation Subsystem (B24) used in the Automated Music Composition and Generation Engine of the present invention. Melody, or a succession of tones comprised of mode, rhythm, and pitches so arranged as to achieve musical shape, is a fundamental building block of any musical piece. The Melody Sub-Phrase Generation Subsystem determines how many melodic sub-phrases are in the melody in the musical piece. This information is based on either user inputs (if given), computationally-determined value(s), or a combination of both.
As shown in FIGS. 27Z1 and 27Z2, the Melody Sub-Phrase Generation Subsystem B24 is supported by the sub-phrase melody placement tables shown in FIG. 28L2, and parameter selection mechanisms (e.g. random number generator, or lyrical-input based parameter selector) described hereinabove.
The Parameter Transformation Engine Subsystem B51 generates the probability-weighted set of melodic sub-phrase length parameter tables for the various musical experience descriptors selected by the system user and provided to the input subsystem B0. In FIG. 27Z1, the probability-based parameter tables employed in the subsystem B24 are set up for the exemplary “emotion-type” musical experience descriptor—HAPPY—and used during the automated music composition and generation process of the present invention.
As shown in FIGS. 27Z1 and 27Z2, for each sub-phrase melody d, e and f, the Melody Sub-Phrase Generation Subsystem B24 accesses the sub-phrase melody placement table, and selects a sub-phrase melody placement using a random number generator, or other parameter selection mechanism, discussed hereinabove.
As shown in the case example, the subsystem B24 might select a table parameter having one half probability that, in a piece 30 seconds in length with 2 phrases consisting of three 5 second sub-phrases each, each of which could contain a melody of a certain length as determined in B25. This is instance, there is a one half probability that all three sub-phrases' melodic lengths might be included in the first phrase's melodic length and a one half probability that only one of the three sub-phrases' total melodic lengths might be included in the first phrase's total melodic length.
As shown in FIGS. 27Z1 and 27Z2, the subsystem B24 make selections from the parameter tables such that the sub-phrase melody length d shall start 3 quarter notes into the sub-phrase, that that the sub-phrase melody length e shall start 2 quarter notes into the sub-phrase, and that the sub-phrase melody length f shall start 3 quarter notes into the sub-phrase. These starting positions for the sub-phrases are the outputs of the Melody Sub-Phrase Generation Subsystem B24, and are illustrated in the first stave in the musical score representation set forth on the bottom of FIG. 27Z2 for the piece of music being composed by the automated music composition process of the present invention.

FIGS. 27DD1, 27DD2 and 27DD3 show the Melody Note Rhythm Generation Subsystem (B26) used in the Automated Music Composition and Generation Engine of the present invention. Rhythm, or the subdivision of a space of time into a defined, repeatable pattern or the controlled movement of music in time, is a fundamental building block of any musical piece. The Melody Note Rhythm Generation Subsystem determines what the default melody note rhythm(s) will be for the musical piece. This information is based on either user inputs (if given), computationally-determined value(s), or a combination of both.
As shown in FIGS. 27DD1, 27DD2 and 27DD3. Melody Note Rhythm Generation Subsystem B26 is supported by the initial note length parameter tables, and the initial and second chord length parameter tables shown in
The Parameter Transformation Engine Subsystem B51 generates the probability-weighted set of parameter tables for the various musical experience descriptors selected by the system user and provided to the input subsystem B0. As shown in FIGS. 27DD1, 27DD2 and 27DD3, the probability-based parameter programming tables employed in the subsystem are set up for the exemplary “emotion-type” musical experience descriptor—HAPPY—and used during the automated music composition and generation process of the present invention.
As shown in FIGS. 27DD1 through 27DD3, Subsystem B26 uses parameter tables loaded by subsystem B51, B40 and B41 to select the initial rhythm for the melody and to create the entire rhythmic material for the melody (or melodies) in the piece. For example, in a melody that is one measure long in a 4/4 meter, there might be a one third probability that the initial rhythm might last for two beats, and based on this information the next chord might last for 1 beat, and based on this information the final chord in the measure might last for 1 beat. The first chord might also last for one beat, and based on this information the next chord might last for 3 beats. This process continues until the entire melodic material for the piece has been rhythmically created and is awaiting the pitch material to be assigned to each rhythm.
Notably, the rhythm of each melody note is dependent upon the rhythms of all previous melody notes; the rhythms of the other melody notes in the same measure, phrase, and sub-phrase; and the melody rhythms of the melody notes that might occur in the future. Each preceding melody notes rhythm determination factors into the decision for a certain melody note's rhythm, so that the second melody note's rhythm is influenced by the first melody note's rhythm, the third melody note's rhythm is influenced by the first and second melody notes' rhythms, and so on.
As shown in FIGS. 27DD1 through 27DD3, the subsystem B26 manages a multi-stage process that (i) selects the initial rhythm for the melody, and (ii) creates the entire rhythmic material for the melody (or melodies) in the piece being composed by the automated music composition machine.
As shown in FIGS. 27DD1 and 27DD2, this process involves selecting the initial note length (i.e. note rhythm) by employing a random number generator and mapping its result to the related probability table. During the first stage, the subsystem B26 uses the random number generator (as described hereinabove), or other parameter selection mechanism discussed hereinabove, to select an initial note length of melody phrase d from the initial note length table that has been loaded into the subsystem. Then, as shown in FIGS. 27DD2 and 27DD3, using the subsystem B26 selects a second note length and then the third chord note length for melody phrase d, using the same methods and the initial and second chord length parameter tables. The process continues until the melody phrase length d is filled with quarter notes. This process is described in greater detail below.
As shown in FIG. 27DD2, the second note length is selected by first selecting the column of the table that matches with the result of the initial note length process and then employing a random number generator and mapping its result to the related probability table. During the second stage, the subsystem B26 starts putting notes into the melody sub-phrase d-e until the melody starts, and the process continues until the melody phrase d-e is filled with notes.
As shown in FIG. 27DD3, the third note length is selected by first selecting the column of the table that matches with the results of the initial and second note length processes and then employing a random number generator and mapping its result to the related probability table. Once the melody phrase d-e is filled with notes, the subsystem B26 starts filling notes into the melody phrase e, during the final stage, and the process continues until the melody phrase e is filled with notes.
As shown in FIGS. 27DD1 through 27DD3, the subsystem B26 then selects piece melody rhythms from the filled phrase lengths, d, d-e and e. The resulting piece melody rhythms are then ready for use during the automated music composition and generation process of the present invention, and are illustrated in the first stave of the musical score representation illustrated at the bottom of FIG. 27DD3.
As shown in
The Parameter Transformation Engine Subsystem B51 generates the probability-weighted data set of initial pitches (i.e. parameter tables) for the various musical experience descriptors selected by the system user and provided to the input subsystem B0. In
In general, the Initial Pitch Generation Subsystem B27 uses the data outputs from other subsystems B26 as well as parameter tables loaded by subsystem B51 to select the initial pitch for the melody (or melodies) in the piece. For example, in a “Happy” piece of music in C major, there might be a one third probability that the initial pitch is a “C”, a one third probability that the initial pitch is a “G”, and a one third probability that the initial pitch is an “F”.
As indicated in
As shown in
FIGS. 27FF1, 27FF2 and 27FF3 show a schematic representation of the Sub-Phrase Pitch Generation Subsystem (B29) used in the Automated Music Composition and Generation Engine of the present invention. The Sub-Phrase Pitch Generation Subsystem B29 determines the sub-phrase pitches of the musical piece. This information is based on either user inputs (if given), computationally-determined value(s), or a combination of both. Pitch, or specific quality of a sound that makes it a recognizable tone, is a fundamental building block of any musical piece.
As shown in FIGS. 27FF1, 27FF2 and 27FF3, the Sub-Phrase Pitch Generation Subsystem (B29) is supported by the melody note table, chord modifier table, the leap reversal modifier table, and the leap incentive modifier tables shown in FIGS. 28O1, 28O2 and 28O3, and parameter selection mechanisms (e.g. random number generator, or lyrical-input based parameter selector) as discussed in detail hereinabove.
The Parameter Transformation Engine Subsystem B51 generates the probability-weighted data set of parameter tables for the various musical experience descriptors selected by the system user and provided to the input subsystem B0. As shown in FIG. 27FF1, the probability-based parameter programming tables employed in the subsystem B29 are set up for the exemplary “emotion-type” musical experience descriptor—HAPPY—and used during the automated music composition and generation process of the present invention.
This subsystem B29 uses previous subsystems as well as parameter tables loaded by subsystem B51 to create the pitch material for the melody (or melodies) in the sub-phrases of the piece.
For example, in a melody that is one measure long in a 4/4 meter with an initial pitch of “C” (for 1 beat), there might be a one third probability that the next pitch might be a “C” (for 1 beat), and based on this information the next pitch be a “D” (for 1 beat), and based on this information the final pitch in the measure might be an “E” (for 1 beat). Each pitch of a sub-phrase is dependent upon the pitches of all previous notes; the pitches of the other notes in the same measure, phrase, and sub-phrase; and the pitches of the notes that might occur in the future. Each preceding pitch determination factors into the decision for a certain note's pitch, so that the second note's pitch is influenced by the first note's pitch, the third note's pitch is influenced by the first and second notes' pitches, and so on. Additionally, the chord underlying the pitch being selected affects the landscape of possible pitch options. For example, during the time that a C Major chord occurs, consisting of notes C E G, the note pitch would be more likely to select a note from this chord than during the time that a different chord occurs. Also, the notes' pitches are encourage to change direction, from either ascending or descending paths, and leap from one note to another, rather than continuing in a step-wise manner. Subsystem B29 operates to perform such advanced pitch material generation functions.
As shown in FIGS. 27FF1, 27FF2 and 27FF3, the subsystem 29 uses a random number generator or other suitable parameter selection mechanisms, as discussed hereinabove, to select a note (i.e. pitch event) from the melody note parameter table, in each sub-phrase to generate sub-phrase melodies for the musical piece being composed.
As shown in FIGS. 27FF1 and 27FF2, the subsystem B29 uses the chord modifier table to change the probabilities in the melody note table, based on what chord is occurring at the same time as the melody note to be chosen. The top row of the melody note table represents the root note of the underlying chord, the three letter abbreviation on the left column represents the chord tonality, the intersecting cell of these two designations represents the pitch classes that will be modified, and the probability change column represents the amount by which the pitch classes will be modified in the melody note table.
As shown in FIGS. 27FF2 and 27FF3, the subsystem B29 uses the leap reversal modifier table to change the probabilities in the melody note table based on the distance (measured in half steps) between the previous note(s).
As shown in FIGS. 27FF2 and 27FF3, the subsystem B29 uses the leap incentive modifier table to change the probabilities in the melody note table based on the distance (measured in half steps) between the previous note(s) and the timeframe over which these distances occurred.
The resulting sub-phrase pitches (i.e. notes) for the musical piece are used during the automated music composition and generation process to generate a part of the piece of music being composed, as illustrated in the first stave of the musical score representation illustrated at the bottom of the process diagram set forth in FIG. 27FF3.
As shown in
The primary function of the sub-phrase melody analyzer is to determine a modified sub-phrase structure(s) in order to change an important component of a musical piece. The sub-phrase melody analyzer considers the melodic, harmonic, and time-based structure(s) of a musical piece, section, phrase, or additional segment(s) to determine its output.
The Parameter Transformation Engine Subsystem B51 generates the probability-weighted set of melodic note rhythm parameter tables for the various musical experience descriptors selected by the system user and provided to the input subsystem B0. As shown in
The Phrase Pitch Generation Subsystem B28 transforms the output of B29 to the larger phrase-level pitch material using the Sub-Phrase Melody Analyzer. The primary function of the sub-phrase melody analyzer is to determine the functionality and possible derivations of a melody(s) or other melodic material. The Melody Sub-Phrase Analyzer uses the tempo, meter, form, chord(s), harmony(s), melody(s), and structure of a piece, section, phrase, or other length of a music piece to determine its output.
Using the inputs all previous phrase and sub-phrase outputs, in combination with data sets and parameter tables loaded by subsystem B51, this subsystem B28 might create a one half probability that, in a melody comprised of two identical sub-phrases, notes in the second occurrence of the sub-phrase melody might be changed to create a more musical phrase-level melody. The sub-phase melodies are modified by examining the rhythmic, harmonic, and overall musical context in which they exist, and altering or adjusting them to better fit their context.
This process continues until the pitch information (i.e. notes) for the entire melodic material has been created. The determined phrase pitch is used during the automated music composition and generation process of the present invention, so as to generate a part of the piece of music being composed, as illustrated in musical score representation set forth in the process diagram of
The resulting phrase pitches for the musical piece are used during the automated music composition and generation process of the present invention so as to generate a part of the piece of music being composed, as illustrated in the first stave of the musical score representation illustrated at the bottom of the process diagram set forth in
FIGS. 27HH1 and 27HH2 show a schematic representation of the Pitch Octave Generation Subsystem (B30) used in the Automated Music Composition and Generation Engine of the present invention. Frequency, or the number of vibrations per second of a musical pitch, usually measured in Hertz (Hz), is a fundamental building block of any musical piece. The Pitch Octave Generation Subsystem B30 determines the octave, and hence the specific frequency of the pitch, of each note and/or chord in the musical piece. This information is based on either user inputs (if given), computationally-determined value(s), or a combination of both.
As shown in FIGS. 27HH1 and 27HH2, the Pitch Octave Generation Subsystem B30 is supported by the melody note octave table shown in
The Parameter Transformation Engine Subsystem B51 generates the probability-weighted set of melody note octave parameter tables for the various musical experience descriptors selected by the system user and provided to the input subsystem B0. In FIGS. 27HH1 and 27HH2, the probability-based parameter tables employed in the subsystem is set up for the exemplary “emotion-type” musical experience descriptor—HAPPY—and used during the automated music composition and generation process of the present invention.
As shown in FIGS. 27HH1 and 27HH2, the melody note octave table is used in connection with the loaded set of notes to determines the frequency of each note based on its relationship to the other melodic notes and/or harmonic structures in a musical piece. In general, there can be anywhere from 0 to just-short-of infinite number of melody notes in a piece. The system automatically determines this number each music composition and generation cycle.
For example, for a note “C,” there might be a one third probability that the C is equivalent to the fourth C on a piano keyboard, a one third probability that the C is equivalent to the fifth C on a piano keyboard, or a one third probability that the C is equivalent to the fifth C on a piano keyboard.
The resulting frequencies of the pitches of notes and chords in the musical piece are used during the automated music composition and generation process of the present invention so as to generate a part of the piece of music being composed, as illustrated in the first stave of the musical score representation illustrated at the bottom of the process diagram set forth in FIG. 27HH2.
FIGS. 27II1 and 27II2 show the Instrumentation Subsystem (B38) used in the Automated Music Composition and Generation Engine of the present invention. The Instrumentation Subsystem B38 determines the instruments and other musical sounds and/or devices that may be utilized in the musical piece. This information is based on either user inputs (if given), compute-determined value(s), or a combination of both, and is a fundamental building block of any musical piece.
As shown in FIGS. 27II1 and 27II2, this subsystem B38 is supported by the instrument tables shown in FIGS. 29Q1A and 29Q1B which are not probabilistic-based, but rather plain tables indicating all possibilities of instruments (i.e. an inventory of possible instruments) separate from the instrument selection tables shown in FIGS. 28Q2A and 28Q2B, supporting probabilities of any of these instrument options being selected.
The Parameter Transformation Engine Subsystem B51 generates the data set of instruments (i.e. parameter tables) for the various “style-type” musical experience descriptors selectable from the GUI supported by input subsystem B0. In FIGS. 27II1 and 27II2, the parameter programming tables employed in the subsystem are set up for the exemplary “style-type” musical experience descriptor—POP—and used during the automated music composition and generation process of the present invention. For example, the style parameter “Pop” might load data sets including Piano, Acoustic Guitar, Electric Guitar, Drum Kit, Electric Bass, and/or Female Vocals.
The instruments and other musical sounds selected for the musical piece are used during the automated music composition and generation process of the present invention so as to generate a part of the piece of music being composed.
FIGS. 27JJ1 and 27JJ2 show a schematic representation of the Instrument Selector Subsystem (B39) used in the Automated Music Composition and Generation Engine of the present invention. The Instrument Selector Subsystem B39 determines the instruments and other musical sounds and/or devices that will be utilized in the musical piece. This information is based on either user inputs (if given), computationally-determined value(s), or a combination of both, and is a fundamental building block of any musical piece.
As shown in FIGS. 27JJ1 and 27JJ2, the Instrument Selector Subsystem B39 is supported by the instrument selection table shown in FIGS. 28Q2A and 28Q2B, and parameter selection mechanisms (e.g. random number generator, or lyrical-input based parameter selector). Using the Instrument Selector Subsystem B39, instruments are selected for each piece of music being composed, as follows. Each Instrument group in the instrument selection table has a specific probability of being selected to participate in the piece of music being composed, and these probabilities are independent from the other instrument groups. Within each instrument group, each style of instrument and each instrument has a specific probability of being selected to participate in the piece and these probabilities are independent from the other probabilities.
The Parameter Transformation Engine Subsystem B51 generates the probability-weighted data set of instrument selection (i.e. parameter) tables for the various musical experience descriptors selectable from the input subsystem B0. In FIGS. 27JJ1 and 27JJ12, the probability-based system parameter tables employed in the subsystem is set up for the exemplary “emotion-type” musical experience descriptor—HAPPY—and “style-type”musical experience descriptor—POP—and used during the automated music composition and generation process of the present invention.
For example, the style-type musical experience parameter “Pop” with a data set including Piano, Acoustic Guitar, Electric Guitar, Drum Kit, Electric Bass, and/or Female Vocals might have a two-thirds probability that each instrument is individually selected to be utilized in the musical piece.
There is a strong relationship between Emotion and style descriptors and the instruments that play the music. For example, a Rock piece of music might have guitars, drums, and keyboards, whereas a Classical piece of music might have strings, woodwinds, and brass. So when a system user selects ROCK music as a style, the instrument selection table will show such instruments as possible selections.
The instruments and other musical sounds selected by Instrument Selector Subsystem B39 for the musical piece are used during the automated music composition and generation process of the present invention so as to generate a part of the piece of music being composed.
FIGS. 27KK1 through 27KK9, taken together, show the Orchestration Generation Subsystem (B31) used in the Automated Music Composition and Generation Engine B31 of the present invention. Orchestration, or the arrangement of a musical piece for performance by an instrumental ensemble, is a fundamental building block of any musical piece. From the composed piece of music, typically represented with a lead sheet (or similar) representation as shown by the musical score representation at the bottom of FIG. 27JJ1, and also at the top of FIG. 27KK6, the Orchestration Generation Subsystem B31 determines what music (i.e. set of notes or pitches) will be played by the selected instruments, derived from the piece of music that has been composed thus far automatically by the automated music composition process. This orchestrated or arranged music for each selected instrument shall determine the orchestration of the musical piece by the selected group of instruments.
As shown in FIGS. 27KK1 through 27KK9, the Orchestration Generation Subsystem (B31) is supported by the following components: (i) the instrument orchestration prioritization tables, the instrument function tables, the piano hand function table, piano voicing table, piano rhythm table, initial piano rhythm table, second note right hand table, second note left hand table, third note right hand length table, and piano dynamics table as shown in FIGS. 28R1, 28R2 and 28R3; (ii) the piano note analyzer illustrated in FIG. 27KK3, system analyzer illustrated in FIG. 27KK7, and master orchestration analyzer illustrated in FIG. 27KK9; and (iii) parameter selection mechanisms (e.g. random number generator, or lyrical-input based parameter selector) as described in detail above. It will be helpful to briefly describe the function of the music data analyzers employed in subsystem B31.
As will be explained in greater detail hereinafter, the primary function of the Piano Note Analyzer illustrated in FIG. 27KK3 is to analyze the pitch members of a chord and the function of each hand of the piano, and then determine what pitches on the piano are within the scope of possible playable notes by each hand, both in relation to any previous notes played by the piano and any possible future notes that might be played by the piano.
The primary function of the System Analyzer illustrated in FIG. 27KK7 is to analyze all rhythmic, harmonic, and timbre-related information of a piece, section, phrase, or other length of a composed music piece to determine and adjust the rhythms and pitches of an instrument's orchestration to avoid, improve, and/or resolve potential orchestrational conflicts.
Also, the primary function of the Master Orchestration Analyzer illustrated in FIG. 27KK9 is to analyze all rhythmic, harmonic, and timbre-related information of a piece, section, phrase, or other length of a music piece to determine and adjust the rhythms and pitches of a piece's orchestration to avoid, improve, and/or resolve potential orchestrational conflicts.
In general, there is a strong relationship between emotion and style descriptors and the instruments that play the music, and the music that selected instruments perform during the piece. For example, a piece of music orchestrated in a Rock style might have a sound completely different than the same piece of music orchestrated in a Classical style. However, the orchestration of the musical piece may be unrelated to the emotion and style descriptor inputs and solely in existence to effect timing requests. For example, if a piece of music needs to accent a certain moment, regardless of the orchestration thus far, a loud crashing percussion instrument such as a cymbal might successfully accomplish this timing request, lending itself to a more musical orchestration in line with the user requests.
As with all the subsystems, Parameter Transformation Engine Subsystem B51 generates the probability-weighted set of possible instrumentation parameter tables identified above for the various musical experience descriptors selected by the system user and provided to the Input Subsystem B0. In FIGS. 27KK1 through 27KK9, the probability-based parameter programming tables (i.e. instrument orchestration prioritization table, instrument energy tabled, piano energy table, instrument function table, piano hand function table, piano voicing table, piano rhythm table, second note right hand table, second note left hand table, piano dynamics table) employed in the Orchestration Generation Subsystem B51 is set up for the exemplary “emotion-type” descriptor—HAPPY—and “style-type” descriptor—POP—and used during the automated music composition and generation process of the present invention. This musical experience descriptor information is based on either user inputs (if given), computationally-determined value(s), or a combination of both.
As illustrated in FIGS. 27KK1 and 27KK2, based on the inputs from subsystems B37, B38, and B39, the Orchestration Generation Subsystem B51 might determine using a random number generation, or other parameter selection mechanism, that a certain number of instruments in a certain stylistic musical category are to be utilized in this piece, and specific order in which they should be orchestrated. For example, a piece of composed music in a Pop style might have a one half probability of 4 total instruments and a one half probability of 5 total instruments. If 4 instruments are selected, the piece might then have a instrument orchestration prioritization table containing a one half probability that the instruments are a piano, acoustic guitar, drum kit, and bass, and a one half probability that the instruments are a piano, acoustic guitar, electric guitar, and bass. In FIG. 27KK1, a different set of priorities are shown for six (6) exemplary instrument orchestrations. As shown, in the case example, the selected instrument orchestration order is made using a random number generator to provide: piano, electric bass 1 and violin.
The flow chart illustrated in FIGS. 27KK1 through 27KK7 describes the orchestration process for the piano—the first instrument to be orchestrated. As shown, the steps in the piano orchestration process include: piano/instrument function selection, piano voicing selection, piano rhythm length selection, and piano dynamics selection, for each note in the piece of music assigned to the piano. Details of these steps will be described below.
As illustrated in FIGS. 27KK1 and 27KK2, the Orchestration Generation Subsystem B51 accesses the preloaded instrument function table, and uses a random function generator (or other parameter selection mechanism) to select an instrument function for each part of the piece of music being composed (e.g. phrase melody, piece melody etc.). The results from this step of the orchestration process include the assignment of a function (e.g. primary melody, secondary melody, primary harmony, secondary harmony or accompaniment) to each part of the musical piece. These function codes or indices will be used in the subsequent stages of the orchestration process as described in detail below.
It is important in orchestration to create a clear hierarchy of each instrument and instrument groups' function in a piece or section of music, as the orchestration of an instrument functioning as the primary melodic instrument might be very different than if it is functioning as an accompaniment. Examples of “instrument function” are illustrated in the instrument function table shown in FIG. 27KK1, and include, for example: primary melody; secondary melody; primary harmony; secondary harmony; and accompaniment. It is understood, however, that there are many more instrument functions that might be supported by the instruments used to orchestrate a particular piece of composed music. For example, in a measure of a “Happy” C major piece of music with a piano, acoustic guitar, drum kit, and bass, the subsystem B31 might assign the melody to the piano, a supportive strumming pattern of the chord to the acoustic guitar, an upbeat rhythm to the drum kit, and the notes of the lowest inversion pattern of the chord progression to the bass. In general, the probabilities of each instrument's specific orchestration are directly affected by the preceding orchestration of the instrument as well as all other instruments in the piece.
Therefore, the Orchestration Generation Subsystem B31 orchestrates the musical material created previously including, but not limited to, the chord progressions and melodic material (i.e. illustrated in the first two staves of the “lead sheet” musical score representation shown in FIGS. 27KK5 and 27KK6) for the specific instruments selected for the piece. The orchestrated music for the instruments in the case example, i.e. violin (Vln.), piano (Pno.) and electric bass (E.B.) shall be represented on the third, fourth/fifth and six staves of the music score representation in FIGS. 27KK6, 27KK7 and 27KK8, respectively, generated and maintained for the musical orchestration during the automated music composition and generation process of the present invention. Notably, in the case example, illustrated in FIGS. 27KK1 through 27KK9, the subsystem B31 has automatically made the following instrument function assignments: (i) the primary melody function is assigned to the violin (Vln.), wherein the orchestrated music for this instrument function will be derived from the lead sheet music composition set forth on the first and second staves and then represented along the third stave of the music representation shown FIG. 27KK6; the secondary melody function is assigned to the right hand (RH) of the piano (Pno.) while the primary harmony function is assigned to the left hand (LH) of the piano, wherein its orchestrated music for these instrument functions will be derived from the lead sheet music composition set forth on the first and second staves and then represented along the fourth and fifth staves of the music representation shown in FIG. 27KK6; and the secondary harmony function is assigned to the electric bass (E.B.), wherein the orchestrated music for this instrument function will be derived from the lead sheet music composition set forth on the first and second staves and then represented along the sixth stave of the music representation shown in FIG. 27KK6.
For the case example at hand, the order of instrument orchestration has been selected to be: (1) the piano performing the secondary melody and primary harmony functions with the RH and LH instruments of the piano, respectively; (2) the violin performing the primary melody function; and (3) the electric base (E.B.) performing the primary harmony function. Therefore, the subsystem B31 will generate orchestrated music for the selected group of instruments in this named order, despite the fact that violin has been selected to perform the primary melody function of the orchestrated music. Also, it is pointed out that multiple instruments can perform the same instrument functions (i.e. both the piano and violin can perform the primary melody function) if and when the subsystem B31 should make this determination during the instrument function step of the orchestration sub-process, within the overall automated music composition process of the present invention. While subsystem B31 will make instrument function assignments un-front during the orchestration process, it is noted that the subsystem B31 will use its System and Master Analyzers discussed above to automatically analyze the entire orchestration of music when completed and determine whether or not if it makes sense to make new instrument function assignments and re-generate orchestrated music for certain instruments, based on the lead sheet music representation of the piece of music composed by the system of the present invention. Depending on how particular probabilistic or stochastic decisions are made by the subsystem B31, it may require several complete cycles through the process represented in FIGS. 27KK1 through 27KK9, before an acceptable music orchestration is produced for the piece of music composed by the automated music composition system of the present invention. This and other aspects of the present invention will become more readily apparent hereinafter.
As shown in the process diagram of FIGS. 27KK1 through 27KK9, once the function of each instrument is determined, then the Subsystem B31 proceeds to load instrument-function-specific function tables (e.g. piano hand function tables) to support (i) determining the manner in which the instrument plays or performs its function, based on the nature of each instrument and how it can be conventionally played, and (ii) generating music (e.g. single notes, diads, melodies and chords) derived from each note represented in the lead sheet musical score for the composed piece of music, so as to create an orchestrated piece of music for the instrument performing its selected instrument function. In the example shown in FIG. 27KK2, the probability-based piano hand function table is loaded for the selected instrument function in the case example, namely: secondary melody. While only the probability-based piano hand function (parameter) table is shown in FIG. 27KK2, for clarity of exposition, it is understood that the Instrument Orchestration Subsystem B31 will have access to probability-based piano hand function table for each of the other instrument functions, namely: primary melody; primary harmony; secondary harmony; and accompaniment. Also, it is understood that the Instrument Orchestration Subsystem B31 will have access to a set of probability-based instrument function tables programmed for each possible instrument function selectable by the Subsystem B31 for each instrument involved in the orchestration process.
Consider, for example, a piano instrument typically played with a left hand and a right hand. In this case, a piano accompaniment in a Waltz (in a ¾ time signature) might have the Left Hand play every downbeat and the Right Hand play every second and third beat of a piece of music orchestrated for the piano. Such instrument-specific function assignment for the piano is carried out by the Instrument Orchestration Subsystem B31 (i) processing each note in the lead sheet of the piece of composed music (represented on the first and staves of the music score representation in FIG. 27KK6), and (ii) generating orchestrated music for both the right hand (RH) and left hand (LH) instruments of the piano, and representing this orchestrated music in the piano hand function table shown in FIGS. 27KK1 and 27KK3. Using the piano hand function table, and a random number generator as described hereinabove, the Subsystem B31 processes each note in the lead sheet musical score and generates music for the right hand and left hand instruments of the piano.
For the piano instrument, the orchestrated music generation process that occurs is carried out by subsystem B31 as follows. For the first note in the lead sheet musical score, the subsystem B31 (i) refers to the probabilities indicated in the RH part of the piano hand function table and, using a random number generator (or other parameter selection mechanism) selects either a melody, single note or chord from the RH function table, to be generated and added to the stave of the RH instrument of the piano, as indicated as the fourth stave shown in FIG. 27KK6; and immediately thereafter (ii) refers to the probabilities indicated in the LH part of the piano hand function table and, using a random number generator (or other parameter selection mechanism) selects from the selected column in the RH function table, either a melody, single note (non-melodic), a diad, or chord, to be generated and added to the stave of the LH instrument of the piano, as indicated as the fifth stave shown in FIG. 27KK6. Notably, a dyad (or diad) is a set of two notes or pitches, whereas a chord has three or more notes, but in certain contexts a musician might consider a dyad a chord—or as acting in place of a chord. A very common two-note “chord” is the interval of a perfect fifth. Since an interval is the distance between two pitches, a dyad can be classified by the interval it represents. When the pitches of a dyad occur in succession, they form a melodic interval. When they occur simultaneously, they form a harmonic interval.
As shown in FIGS. 27KK1 and 27KK2, the Instrument Orchestration Subsystem 31 determines which of the previously generated notes are possible notes for the right hand and left hand parts of the piano, based on the piece of music composed thus far. This function is achieved the subsystem B31 using the Piano Note Analyzer to analyze the pitch members (notes) of a chord, and the selected function of each hand of the piano, and then determines what pitches on the piano (i.e. notes associated with the piano keys) are within the scope of possible playable notes by each hand (i.e. left hand has access to lower frequency notes on the piano, whereas the right hand has access to higher frequency notes on the piano) both in relation to any previous notes played by the piano and any possible future notes that might be played by the piano. Those notes that are not typically playable by a particular human hand (RH or LH) on the piano, are filtered out or removed from the piece music orchestrated for the piano, while notes that are playable should remain in the data structures associated with the piano music orchestration.
Once the notes are generated for each piano hand, as shown in FIGS. 27KK3 and 27KK4, the subsystem B31 then performs piano voicing which is a process that influences the vertical spacing and ordering of the notes (i.e. pitches) in the orchestrated piece of music for the piano. For example, the instrument voicing influences which notes are on the top or in the middle of a chord, which notes are doubled, and which octave each note is in. Piano voicing is achieved by the Subsystem B31 accessing a piano voicing table, schematically illustrated in FIGS. 27KK1 and 27KK2 as a simplistic two column table, when in reality, it will be a complex table involving many columns and rows holding parameters representing the various ways in which a piano can play each musical event (e.g. single note (non-melodic), chord, diad or melody) present in the orchestrated music for the piano at this stage of the instrument orchestration process. As shown in the piano, voicing table, following conventional, each of the twelve notes or pitches on the musical scale is represented as a number from 0 through 11, where musical note C is assigned number 0, C sharp is assigned 1, and so forth. While the exemplary piano voicing table of FIG. 27KK3 only shows the possible LH and RH combination for single-note (non-melodic) events that might occur within a piece of orchestrated music, it is understood that this piano voicing table in practice will contain voicing parameters for many other possible musical events (e.g. chords, diads, and melodies) that are likely to occur within the orchestrated music for the piano, as is well known in the art.
Once the manner in which an instrument is going to play generated notes in the piano orchestrated music has been determined as described above, the subsystem B31 determines the specifics, including the note lengths or duration (i.e. note rhythms) using the piano rhythm tables shown in FIGS. 27KK4 and 27KK5, and continues to specify the note durations for the orchestrated piece of music until piano orchestration is filled. As shown in FIG. 27KK5, the piano note rhythm (i.e. note length) specification process is carried out using as many stages as memory and data processing will allow within the system of the present invention. In the illustrative embodiment, three stages are supported within subsystem B31 for sequentially processing an initial (first) note, a second (sequential) note and a third (sequential) note using (i) the probabilistic-based initial piano rhythm (note length) table having left hand and right hand components, (ii) the second piano rhythm (note length) table having left hand and right hand components, and (iii) the third piano rhythm (note length) table having left hand and right hand components, as shown in FIGS. 27KK4 and 27KK5. Notably, for this 3rd-order stochastic model, the probability values contained in the right-hand second piano rhythm (note length) table are dependent upon the initial notes that might be played by the right hand instrument of the piano and observed by the subsystem B31, and the probability values the probability values contained in the right-hand third piano rhythm (note length) table are dependent in the initial notes that might be played by the right hand instrument of the piano and observed by the subsystem B31. Likewise, the probability values contained in the left-hand second piano rhythm (note length) table are dependent upon the initial notes that might be played by the left hand instrument of the piano and observed by the subsystem B31, and the probability values the probability values contained in the left-hand third piano rhythm (note length) table are dependent in the initial notes that might be played by the left hand instrument of the piano and observed by the subsystem B31.
If a higher order stochastic model where used for piano note rhythm (i.e. note length) control, then a fourth order and perhaps higher order piano (note) rhythm (note length) tables will be used to carry out the orchestration process supported within the subsystem B31. The result from this stage of note processing are notes of specified note length or duration in the orchestrated piece of music for the piano, as illustrated in musical score representation shown in FIG. 27KK6.
Regardless of the order of the stochastic model used, the Instrument Orchestration Subsystem B31 will need to determine the proper note lengths (i.e. note rhythms) in each piece of orchestrated music for a given instrument. So, for example, continuing the previous example, if the left hand instrument of the piano plays a few notes on the downbeat, it might play some notes for an eighth note or a half note duration. Each note length is dependent upon the note lengths of all previous notes; the note lengths of the other notes in the same measure, phrase, and sub-phrase; and the note lengths of the notes that might occur in the future. Each preceding note length determination factors into the decision for a certain note's length, so that the second note's length is influenced by the first note's length, the third note's length is influenced by the first and second notes' lengths, and so on.
Having determined the note lengths for the piano orchestration, the next step performed by the subsystem B31 is to determine the “dynamics” for the piano instrument as represented by the piano dynamics table indicated in the process diagram shown in FIG. 27KK6. In general, the dynamics refers to the loudness or softness of a musical composition, and piano or instrument dynamics relates to how the piano or instrument is played to impart particular dynamic characteristics to the intensity of sound generated by the instrument while playing a piece of orchestrated music. Such dynamic characteristic will include loudness and softness, and the rate at which sound volume from the instrument increases or decreases over time as the composition is being performed. As reflected in the piano dynamics table set forth in the process diagram of FIG. 27KK7, several traditional classes of “dynamics” have been developed for the piano over the past several hundred years or so, namely: (i) piano (soft); mezzo piano; mezzo forte. In each case, instrument dynamics relates to how the instrument is played or performed by the automated music composition and generation system of the present invention, or any resultant system, in which the system may be integrated and requested to compose, generate and perform music in accordance with the principles of the present invention.
As shown in FIG. 27KK6, dynamics for the piano instrument are determined using the piano dynamics table shown in FIGS. 28R1, 28R2 and 28R3 and the random number generator (or other parameter selection mechanism) to select a piano dynamic for the first note played by the right hand instrument of the piano, and then the left hand instrument of the piano. While the piano dynamics table shown in FIG. 27KK6 is shown as a first-order stochastic model for purposes of simplicity and clarity of exposition, it is understood that in practice the piano dynamics table (as well as most instrument dynamics tables) will be modeled and implemented as an n-th order stochastic process, where each note dynamics is dependent upon the note dynamic of all previous notes; the note dynamics of the other notes in the same measure, phrase, and sub-phrase; and the note dynamics of the notes that might occur in the future. Each preceding note dynamics determination factors into the decision for a certain note's dynamics, so that the second note's dynamics is influenced by the first note's dynamics, the third note's dynamics is influenced by the first and second notes' dynamics, and so on. In some cases, the piano dynamics table will be programmed so that there is a gradual increase or decrease in volume over a specific measure or measures, or melodic phrase or phrases, or sub-phrase or sub-phrase, or over an entire melodic piece, in some instances. In other instances, the piano dynamics table will be programmed so that the piano note dynamics will vary from one specific measure to another measure, or from melodic phrase to another melodic phrase, or from one sub-phrase or another sub-phrases, or over from one melodic piece to another melodic phrase, in other instances. In general, the dynamics of the instrument's performance will be ever changing, but are often determined by guiding indications that follow the classical music theory cannon. How such piano dynamics tables might be designed for any particular application at hand will occur to those skilled in the art having had the benefit of the teachings of the present invention disclosure.
This piano dynamics process repeats, operating on the next note in the orchestrated piano music represented in the fourth stave of the music score representation in FIG. 27KK7 for the right hand instrument of the piano, and on the next note in the orchestrated piano music represented in the fifth stave of the music score representation in FIG. 27KK7 for the left hand instrument of the piano. The dynamics process is repeated and operates on all notes in the piano orchestration until all piano dynamics have been selected and imparted for all piano notes in each part of the piece assigned to the piano. As shown, the resulting musical score representation, with dynamics markings (e.g. p, mf, f) for the piano is illustrated in the top of
As indicated in FIG. 27KK7, the entire Subsystem B31 repeats the above instrument orchestration process for the next instrument (e.g. electric bass 1) so that orchestrated music for the electric bass is generated and stored within the memory of the system, as represented in the sixth stave of the musical score representation shown in FIG. 27KK8.
As shown in FIGS. 27KK7 and 27KK8, while orchestrating the electric bass instrument, the subsystem B31 uses the System Analyzer to automatically check for conflicts between previously orchestrated instruments. As shown, the System Analyzer adjusts probabilities in the various tables used in subsystem B31 so as to remove possible conflicts between orchestrated instruments. Examples of possible conflicts between orchestrated instrument might include, for example: when an instrument is orchestrated into a pitch range that conflicts with a previous instrument (i.e. an instrument plays the exact same pitch/frequency as another instrument that makes the orchestration of poor quality); where an instrument is orchestrated into a dynamic that conflicts with a previous instrument (i.e. all instruments are playing quietly and one instrument is now playing very loudly); and where an instrument is orchestrated to do something that is not physically possible by a real musician in light of previous orchestrations (i.e. a single percussionist cannot play 8 drum kits at once). FIG. 27KK8 shows the musical score representation for the corrected musical instrumentation played by the electric bass (E.B) instrument.
As shown at the bottom of FIG. 27KK8, the Subsystem B31 repeats the above orchestration process for next instrument (i.e. violin) in the instrument group of the music composition. The musical score representation for the orchestrated music played by the violin is set forth in the third stave shown in the topmost music score representation set froth in the process diagram of FIG. 27KK9.
As shown in FIG. 27KK9, once the orchestration is complete, the Orchestration Generation Subsystem B13 uses the Master Orchestration Analyzer to modify and improve the resulting orchestration and corrects any musical or non-musical errors and/or inefficiencies. In this example, the octave notes in the second and third base clef staves of the piano orchestration in FIG. 27KK9 have been removed, as shown in the final musical score representation set forth in the lower part of the process diagram set forth in FIG. 27KK9, produced at the end of this stage of the orchestration process.
The instruments and other musical sounds selected for the instrumentation of the musical piece are used during the automated music composition and generation process of the present invention so as to generate a part of the piece of music being composed, as illustrated in the musical score representation illustrated at the bottom of FIG. 27KK9.
The Controller Code Generation Subsystem B32 determines the controller code and/or similar information of each note that will be used in the piece of music being composed and generated. This Subsystem B32 determines and generates the “controller code” information for the notes and chords of the musical being composed. This information is based on either system user inputs (if given), computationally-determined value(s), or a combination of both.
As shown in
Each instrument, instrument group, and piece has specific independent probabilities of different processing effects, controller code data, and/or other audio/midi manipulating tools being selected for use. With each of the selected manipulating tools, the subsystem B32 then determines in what manner the selected tools will affect and/or change the musical piece, section, phrase, or other structure(s); how the musical structures will affect each other; and how to create a manipulation landscape that improves the musical material that the controller code tools are manipulating.
The Parameter Transformation Engine Subsystem B51 generates the probability-weighted data set of possible controller code (i.e. parameter) tables for the various musical experience descriptors selected by the system user and provided to the input subsystem B0. In
The Controller Code Generation Subsystem B32 uses the instrument, instrument group and piece-wide controller code parameter tables and data sets loaded from subsystems B1, B37, B38, B39, B40, and/or B41. As shown in
In general, there is a strong relationship between emotion and style descriptors and the controller code information that informs how the music is played. For example, a piece of music orchestrated in a Rock style might have a heavy dose of delay and reverb, whereas a Vocalist might incorporate tremolo into the performance. However, the controller code information used to generate a musical piece may be unrelated to the emotion and style descriptor inputs and solely in existence to effect timing requests. For example, if a piece of music needs to accent a certain moment, regardless of the controller code information thus far, a change in the controller code information, such as moving from a consistent delay to no delay at all, might successfully accomplish this timing request, lending itself to a more musical orchestration in line with the user requests.
The controller code selected for the instrumentation of the musical piece will be used during the automated music composition and generation process of the present invention as described hereinbelow.
The Automatic Music Composition And Generation (i.e. Production) System of the present invention described herein utilizes libraries of digitally-synthesized (i.e. virtual) musical instruments, or virtual-instruments, to produce digital audio samples of individual notes specified in the musical score representation for each piece of composed music. These digitally-synthesized (i.e. virtual) instruments shall be referred to as the Digital Audio Sample Producing Subsystem, regardless of the actual techniques that might be used to produce each digital audio sample that represents an individual note in a composed piece of music.
In general, to generate music from any piece of music composed by the system, Subsystems B33 and B34 need musical instrument libraries for acoustically realizing the musical events (e.g. pitch events such as notes, and rhythm events) played by virtual instruments specified in the musical score representation of the piece of composed music. There are many different techniques available for creating, designing and maintaining music instrument libraries, and musical sound libraries, for use with the automated music composition and generation system of the present invention, namely: Digital Audio Sampling Synthesis Methods; Partial Timbre Synthesis Methods, Frequency Modulation (FM) Synthesis Methods; and other forms of Virtual Instrument Synthesis Technology.
The Digital Audio Sampling Synthesis Method involves recording a sound source (such as a real instrument or other audio event) and organizing these samples in an intelligent manner for use in the system of the present invention. In particular, each audio sample contains a single note, or a chord, or a predefined set of notes. Each note, chord and/or predefined set of notes is recorded at a wide range of different volumes, different velocities, different articulations, and different effects, etc. so that a natural recording of every possible use case is captured and available in the sampled instrument library. Each recording is manipulated into a specific audio file format and named and tagged with meta-data with identifying information. Each recording is then saved and stored, preferably, in a database system maintained within or accessible by the automatic music composition and generation system. For example, on an acoustical piano with 88 keys (i.e. notes), it is not unexpected to have over 10,000 separate digital audio samples which, taken together, constitute the fully digitally-sampled piano instrument. During music production, these digitally sampled notes are accessed in real-time to generate the music composed by the system. Within the system of the present invention, these digital audio samples function as the digital audio files that are retrieved and organized by subsystems B33 and B34, as described in detail below.
Using the Partial Timbre Synthesis Method, popularized by New England Digital's SYNCLAVIER Partial-Timbre Music Synthesizer System in the 1980's, each note along the musical scale that might be played by any given instrument being model (for partial timbre synthesis library) is sampled, and its partial timbre components are stored in digital memory. Then during music production/generation, when the note is played along in a given octave, each partial timbre component is automatically read out from its partial timbre channel and added together, in an analog circuit, with all other channels to synthesize the musical note. The rate at which the partial timbre channels are read out and combined determines the pitch of the produced note. Partial timbre-synthesis techniques are taught in U.S. Pat. Nos. 4,554,855; 4,345,500; and 4,726,067, incorporated by reference.
Using state-of-the-art Virtual Instrument Synthesis Methods, such as supported by MOTU's MachFive 3 Universal Sampler and Virtual Music Instrument Design Tools, musicians can create custom sound libraries for almost any virtual instrument, real or imaginable, to support music production (i.e. generation) in the system of the present invention.
There are other techniques that have been developed for musical note and instrument synthesis, such as FM synthesis, and these technologies can be found employed in various commercial products for virtual instrument design and music production.
FIG. 27OO1 shows the Piece Format Translator Subsystem (B50) used in the Automated Music Composition and Generation Engine (E1) of the present invention. The Piece Format Translator subsystem B50 analyzes the audio and text representation of the digital piece and creates new formats of the piece as requested by the system user or system including. Such new formats may include, but are not limited to, MIDI, Video, Alternate Audio, Image, and/or Alternate Text format. Subsystem B50 translates the completed music piece into desired alterative formats requested during the automated music composition and generation process of the present invention.
FIGS. 27QQ1, 27QQ2 and 27QQ3 show the Feedback Subsystem (B42) used in the Automated Music Composition and Generation Engine of the present invention. As shown the input and output data ports of the Feedback Subsystem B42 is are configured with the data input and output ports shown in
In general, during system operation, the Feedback Subsystem B42 allows for inputs ranging from very specific to very vague and acts on this feedback accordingly. For example, a user might provide information, or the system might determine on its on accord, that the piece that was generated should, for example, be (i) faster (i.e. have increased tempo), (ii) greater emphasize on a certain musical experience descriptor, change timing parameters, and (iii) include a specific instrument. This feedback can be given through a previously populated list of feedback requests, or an open-ended feedback form, and can be accepted as any word, image, or other representation of the feedback.
As shown in FIGS. 27QQ1, 27QQ2 and 27QQ3, the Piece Feedback Subsystem B42 receives various kinds of data from its data input ports, and this data is autonomously analyzed by a Piece Feedback Analyzer supported within Subsystem B42. In general, the Piece Feedback Analyzer considers all available input, including, but not limited to, autonomous or artificially intelligent measures of quality and accuracy and human or human-assisted measures of quality and accuracy, and determines a suitable response to a analyzed piece of composed music. Data outputs from the Piece Feedback Analyzer can be limited to simple binary responses and can be complex, such as dynamic multi-variable and multi-state responses. The analyzer then determines how best to modify a musical piece's rhythmic, harmonic, and other values based on these inputs and analyses. Using the system-feedback architecture of the present invention, the data in any composed musical piece can be transformed after the creation of the entire piece of music, section, phrase, or other structure, or the piece of music can be transformed at the same time as the music is being created.
As shown in FIG. 27QQ1, the Feedback Subsystem B41 performs Autonomous Confirmation Analysis. Autonomous Confirmation Analysis is a quality assurance/self-checking process, whereby the system examines the piece of music that was created, compares it against the original system inputs, and confirms that all attributes of the piece that was requested have been successfully created and delivered and that the resultant piece is unique. For example, if a Happy piece of music ended up in a minor key, the analysis would output an unsuccessful confirmation and the piece would be recreated. This process is important to ensure that all musical pieces that are sent to a user are of sufficient quality and will match or surpass a user's expectations.
As shown in FIG. 27QQ1, the Feedback Subsystem B42 analyzes the digital audio file and additional piece formats to determine and confirm (i) that all attributes of the requested piece are accurately delivered, (ii) that digital audio file and additional piece formats are analyzed to determine and confirm “uniqueness” of the musical piece, and (iii) the system user analyzes the audio file and/or additional piece formats, during the automated music composition and generation process of the present invention. A unique piece is one that is different from all other pieces. Uniqueness can be measured by comparing all attributes of a musical piece to all attributes of all other musical pieces in search of an existing musical piece that nullifies the new piece's uniqueness.
As indicated in FIGS. 27QQ1, 27QQ2 and 27QQ3, if musical piece uniqueness is not successfully confirmed, then the feedback subsystem B42 modifies the inputted musical experience descriptors and/or subsystem music-theoretic parameters, and then restarts the automated music composition and generation process to recreate the piece of music. If musical piece uniqueness is successfully confirmed, then the feedback subsystem B42 performs User Confirmation Analysis. User confirmation analysis is a feedback and editing process, whereby a user receives the musical piece created by the system and determines what to do next: accept the current piece, request a new piece based on the same inputs, or request a new or modified piece based on modified inputs. This is the point in the system that allows for editability of a created piece, equal to providing feedback to a human composer and setting him off to enact the change requests.
Thereafter, as indicated in FIG. 27QQ2, the system user analyzes the audio file and/or additional piece formats and determines whether or not feedback is necessary. To perform this analysis, the system user can (i) listen to the piece(s) or music in part or in whole, (ii) view a score file (represented with standard MIDI conventions), or otherwise (iii) interact with the piece of music, where the music might be conveyed with color, taste, physical sensation, etc., all of which would allow the user to experience the piece of music.
In the event that feedback is not determined to be necessary, then the system user either (i) continues with the current music piece, or (ii) uses the exact same user-supplied input musical experience descriptors and timing/spatial parameters to create a new piece of music using the system. In the event that feedback is determined to be necessary, then the system user provides/supplied desired feedback to the system. Such system user feedback may take on the form of text, linguistics/language, images, speech, menus, audio, video, audio/video (AV), etc.
In the event the system users desires to provide feedback to the system via the GUI of the input output subsystem B0, then a number of feedback options will be made available to the system user through a system menu supporting, for example, five pull-down menus.
As shown in FIGS. 22QQ2 and 27QQ3, the first pull down menus provides the system user with the following menu options: (i) faster speed; (ii) change accent location; (iii) modify descriptor, etc. The system user can make any one of these selections and then request the system to regenerate a new piece of composed music with these new parameters.
As shown in FIGS. 27QQ2 and 27QQ3, the second pull down menu provides the system user with the following menu options: (i) replace a section of the piece with a new section; (ii) when the new section follows existing parameters, modify the input descriptors and/or subsystem parameter tables, then restart the system and recreate a piece or music; and (iii) when the new section follows modified and/or new parameters, modify the input descriptors and/or subsystem parameter tables, then restart the system and recreate a piece or music. The system user can make any one of these selections and then request the system to regenerate a new piece of composed music.
As shown in FIGS. 27QQ2 and 27QQ3, the third pull down menu provides the system user with the following options: (i) combine multiple pieces into fewer pieces; (ii) designate which pieces of music and which parts of each piece should be combined; (iii) system combines the designated sections; and (iv) use the transition point analyzer and recreate transitions between sections and/or pieces to create smoother transitions. The system user can make any one of these selections and then request the system to regenerate a new piece of composed music.
As shown in FIGS. 27QQ2 and 27QQ3, the fourth pull down menu provides the system user with the following options: (i) split piece into multiple pieces; (ii) within existing pieces designate the desired start and stop sections for each piece; (iii) each new piece automatically generated; and (iv) use split piece analyzer and recreate the beginning and end of each new piece so as to create smoother beginning and end. The system user can make any one of these selections and then request the system to regenerate a new piece of composed music.
As shown in FIGS. 27QQ2 and 27QQ3, the fourth pull down menu provides the system user with the following options: (i) compare multiple pieces at once; (ii) select pieces to be compared; (iii) select pieces to be compared; (iv) pieces are lined up in sync with each other; (v) each piece is compared, and (vi) preferred piece is selected. The system user can make any one of these selections and then request the system to regenerate a new piece of composed music.
As shown in
The primary functionality of the Feedback analyzer is to determine an avenue for analysis and improvement of a musical piece, section, phrase, or other structure(s). The Feedback Analyzer considers the melodic, harmonic, and time-based structure(s) as well as user or computer-based input (both musical and non-musical) to determine its output.

In general, the subsystem B45 determines the musical “kernel” of a music piece in terms of (i) melody (sub-phrase melody note selection order), (ii) harmony (i.e. phrase chord progression), (iii) tempo, (iv) volume, and (v) orchestration, so that this music kernel can be used during future automated music composition and generation process of the present invention. This information may be used to replicate, either with complete or incomplete accuracy, the piece of music at a later time.
For example, the Subsystem B45 may save the melody and all related melodic and rhythmic material, of a musical piece so that a user may create a new piece with the saved melody at a later time. It may also analyze and save the information from B32 in order to replicate the production environment and data of the piece.
FIG. 27SUU shows the user taste generation subsystem (B46) used in the Automated Music Composition and Generation Engine of the present invention. The subsystem determines the system user's musical taste based on system user feedback and autonomous piece analysis, and this musical taste information is used to change or modify the musical experience descriptors, parameters and table values, logic order, and/or other elements of the system for a music composition in order or to better reflect the preferences of a user.
In general, the subsystem B46 analyzes the user's personal musical and non-musical taste and modifies the data sets, data tables, and other information used to create a musical piece in order to more accurately and quickly meet a user's request in the future. For example, this subsystem may recognize that a user's request for “Happy” music is most satisfied when sad music is generated, even though this is not what the system believes should be the case. In this case, the system would modify all relevant subsystems and data so that sad music is generated for this user when the “Happy” request is made. These changes and preferences are then saved to a user's individual profile and will be recalled and reused and potentially re-modified as the user continues to use the system.

In response, the subsystem B46 performs its functions and the piece is recreated. The second piece created replaces the strings with an electric guitar. In response, the system user provides feedback to subsystem B46: more romantic. In response, the subsystem B46 performs its functions and the piece is recreated. The third piece created adds a piano to the electric guitar and the system user provides feedback to the subsystem B46: perfect. In response, the subsystem B46 modifies the instrumentation parameter table for this system user with the romantic descriptor so as to increase the probability of electric guitar and piano being used, and decreasing the probability of using strings during the instrumentation process.
For example, this subsystem may recognize that the entire user base's requests for “Happy” music are most satisfied when sad music is generated, even though this is not what the system believes should be the case. In this case, the system would modify all relevant subsystems and data so that sad music is generated for the entire user base when the “Happy” request is made by an individual user. These changes and preferences are then saved on a population level and will be recalled and reused and potentially re-modified as the system's users continue to use the system.

When practicing the systems and methods of the present invention, system designers and engineers will make use of various principles described below when designing, constructing and operating the Parameter Transformation Engine Subsystem B51 in accordance with the principles of the present invention. The essence of the present invention is to enable or empower system users (e.g. human beings as well as advanced computing machines) to specify the emotional, stylistic and timing aspects of music to be composed without requiring any formal knowledge of music or music theory. However, to realize this goal, the systems of the present invention need to employ powerful and rich music theoretic concepts and principles which are practiced strongly within the parameter transformation engine B51, where system user inputs are transformed into probabilistic-weight music-theoretic parameters that are loaded into the system operating parameter (SOP) tables and distributed across and loaded within the various subsystems for which they are specifically intended and required for proper system operation.
Transforming Musical Experience Parameters into Probabilistic-Based System Operating Parameters Maintained in the Parameter Tables of Subsystem B2
If the user provides the piece length, then no length parameter tables are used. If the user does not provide the piece length, then the system parameter table determines the piece length. If the music is being created to accompany existing content, then the length is defaulted to be the length of the existing content. If the music is not being created to accompany existing content, the length is decided based on a probability table with lengths and probabilities based on the musical emotion and style descriptor inputs. For example, a Pop song may have a 50% chance of having a three minute length, 25% chance of a two minute length, and 25% chance of having a four minute length, whereas a Classical song may have a 50% chance of having a six minute length, 25% chance of a five minute length, and 25% chance of having a seven minute length.

In general, there is a strong relationship between Emotion and style descriptors and tempo. For example, music classified as Happy is often played at a moderate to fast tempo, whereas music classified as Sad is often played a slower tempo. The system's tempo tables are reflections of the cultural connection between a musical experience and/or style and the speed at which the material is delivered. Tempo is also agnostic to the medium of the content being delivered, as speech said in a fast manner is often perceived as rushed or frantic and speech said in a slow manner is often perceived as deliberate or calm.
Further, tempo(s) of the musical piece may be unrelated to the emotion and style descriptor inputs and solely in existence to line up the measures and/or beats of the music with certain timing requests. For example, if a piece of music a certain tempo needs to accent a moment in the piece that would otherwise occur somewhere between the fourth beat of a measure and the first beat of the next measure, an increase in the tempo of a measure preceding the desired accent might cause the accent to occur squarely on the first beat of the measure instead, which would then lend itself to a more musical accent in line with the downbeat of the measure.
Transforming Musical Experience Parameters into System Operating Parameter Tables Maintained in the Parameter Tables of Subsystem B4
There is a strong relationship between Emotion and style descriptors and meter. For example, a waltz is often played with a meter of ¾, whereas a march is often played with a meter of 2/4. The system's meter tables are reflections of the cultural connection between a musical experience and/or style and the meter in which the material is delivered.
Further, meter(s) of the musical piece may be unrelated to the emotion and style descriptor inputs and solely in existence to line up the measures and/or beats of the music with certain timing requests. For example, if a piece of music a certain tempo needs to accent a moment in the piece that would otherwise occur on halfway between the fourth beat of a 4/4 measure and the first beat of the next 4/4 measure, an change in the meter of a single measure preceding the desired accent to ⅞ would cause the accent to occur squarely on the first beat of the measure instead, which would then lend itself to a more musical accent in line with the downbeat of the measure.
The above principles and considerations will be used by the system designer(s) when defining or creating “transformational mappings” (i.e. statistical or theoretical relationships) between (i) certain allowable combinations of emotion, style and timing/spatial parameters supplied by the system user(s) to the input output subsystem B0 of the system, and (ii) certain music-theoretic parameters (i.e. values) stored in system operating parameter (SOP) tables that are loaded into subsystem B4 and used during the automated music composition and generation system of the present invention.
Transforming Musical Experience Parameters into Probabilistic-Based System Operating Parameters Maintained in the Parameter Tables of Subsystem B5
There is a strong relationship between Emotion and style descriptors and key. For example, Pop music is often played in keys with none or a few sharps (e.g. C, G, D, A, E), whereas Epic music is often played in keys with a few or more flats (e.g. F, Bb, Eb, Ab). The system's key tables are reflections of the cultural connection between a musical experience and/or style and the key in which the material is delivered.
Further, keys(s) of the musical piece may be unrelated to the emotion and style descriptor inputs and solely in existence to reflect timing requests. For example, if a moment needs to elevate the tension of a piece, modulating the key up a minor third might achieve this result. Additionally, certain instruments perform better in certain keys, and the determination of a key might take into consideration what instruments are likely to play in a certain style. For example, in a classical style where violins are likely to play, it would be much more preferable to create a piece of music in a key with none or few sharps than with any flats.
Taking into consideration all of the system user selected inputs through subsystem B0, the key generation subsystem B5 creates the key(s) of the piece. For example, a piece with an input descriptor of “Happy,” a length of thirty seconds, a tempo of sixty beats per minute, and a meter of 4/4 might have a one third probability of using the key of C (or 1, on a 1-12 scale, or 0 on a 1-11 scale), a one third probability of using the key of G (or 8, on a 1-12 scale, or 7 on a 1-11 scale), or a one third probability of using the key of A (or 10, on a 1-12 scale, or 9 on a 1-11 scale). If there are multiple sections, music timing parameters, and/or starts and stops in the music, multiple keys might be selected.
The above principles and considerations will be used by the system designer(s) when defining or creating “transformational mappings” (i.e. statistical or theoretical relationships) between (i) certain allowable combinations of emotion, style and timing/spatial parameters supplied by the system user(s) to the input output subsystem B0 of the system, and (ii) certain music-theoretic parameters (i.e. values) stored in system operating parameter (SOP) tables that are loaded into subsystem B5 and used during the automated music composition and generation system of the present invention.
Transforming Musical Experience Parameters into Probabilistic-Based System Operating Parameters Maintained in the Parameter Tables of Subsystem B7
There is a strong relationship between Emotion and style descriptors and tonality. For example, Happy music is often played with a Major tonality, whereas Sad music is often played with a Minor tonality. The system's key tables are reflections of the cultural connection between a musical experience and/or style and the tonality in which the material is delivered.
Further, tonality(s) of the musical piece may be unrelated to the emotion and style descriptor inputs and solely in existence to reflect timing requests. For example, if a moment needs to transition from a tense period to a celebratory one, changing the tonality from minor to major might achieve this result.
A user is not required to know or select the tonality of the piece of music to be created. Tonality has a direct connection with the cultural canon, and the parameters and probabilities that populate this table are based on a deep knowledge and understanding of this history. For example, Happy music is often created in a Major tonality, Sad music is often created in a Minor tonality, and Playful music is often created in a Lydian tonality. The user musical emotion and style descriptor inputs are responsible for determining which tonalities are possible options for the piece of music and how likely each possibility will be.
The above principles and considerations will be used by the system designer(s) when defining or creating “transformational mappings” (i.e. statistical or theoretical relationships) between (i) certain allowable combinations of emotion, style and timing/spatial parameters supplied by the system user(s) to the input output subsystem B0 of the system, and (ii) certain music-theoretic parameters (i.e. values) stored in system operating parameter (SOP) tables that are loaded into subsystem B7 and used during the automated music composition and generation system of the present invention.
Transforming Musical Experience Parameters into Probabilistic-Based System Operating Parameters Maintained in the Parameter Tables of Subsystem B9
All music has a form, even if the form is empty, unorganized, or absent. Pop music traditionally has form elements including Intro, Verse, Chorus, Bridge, Solo, Outro, etc. Also, song form phrases can have sub-phrases that provide structure to a song within the phrase itself.
Each style of music has established form structures that are readily associated with the style. Outside of Pop music, a Classical sonata might have a form of Exposition Development Recapitulation (this is simplified, of course), where the Recapitulation is modified presentation of Exposition. This might be represented as ABA′, where the signifies the modified presentation of the original “A” materials.
The song form is also determined by the length of the musical piece. The longer a piece of music, the greater flexibility and options that exist for the form of the piece. In contrast, a 5 second piece of music can only realistically have a few limited form options (often a single A form). Further, timing events might influence a song form. If it is necessary to signify a huge shift in a piece of music, including a chorus or B section might effectively create this shift.
Emotion can also influence song form as well. For example, songs described as a love song, might have a typical forms associated with them, following cultural cannons, whereas songs that are described as Celtic might have very different song forms.
The above principles and considerations will be used by the system designer(s) when defining or creating transformational mappings between (i) certain allowable combinations of emotion, style and timing/spatial parameters supplied by the system user(s) to the input output subsystem B0 of the system, and (ii) certain music-theoretic parameters stored in system operating parameter tables that are loaded into subsystem B9 and used during the automated music composition and generation system of the present invention.
Transforming Musical Experience Parameters into Probabilistic-Based System Operating Parameters Maintained in the Parameter Tables of Subsystem B15
In general, the sub-phrase lengths are determined by (i) the overall length of the phrase (i.e. a phrase of 2 seconds will have many fewer sub-phrase options that a phrase of 200 seconds), (ii) the timing necessities (i.e. parameters) of the piece, and (iii) the style and emotion-type musical experience descriptors.
The amount, length, and probability of Sub-phrase lengths are dependent on the piece length and on the knowledge of which combinations of the previously mentioned characteristics best fit together when creating a piece of music. Sub-phrase lengths are influenced by the Emotion and Style descriptors provided by the system user. For example, Happy types of music might call for shorter sub-phrase lengths whereas Sad types of music might call for longer sub-phrase lengths.
The greater amount of sub-phrases, the less likely each is to have a very large length. And the fewer amount of sub-phrases, the more likely each is to have a very large length.
Sub-phrases also have to fit within the length of a piece of music and a specific phrase, so as certain sub-phrases are decided, future sub-phrase decisions and related parameters might be modified to reflect the remaining length that is available.
Sub-phrases might also be structured around user-requested timing information, so that the music naturally fits the user's request. For example, if a user requests a change in the music that happens to be 2 measures into the piece, the first sub-phrase length might be two measures long, caused by a complete 100% probability of the sub-phrase length being two measures long.
This parameter transformation engine subsystem B51 analyzes all of the system user input parameters and then generates and loads a probability-weighted data set of rhythms and lengths in the SOP tables, based on the input all previous processes in the system. Taking into consideration these inputs, this system creates the sub-phrase lengths of the piece. For example, a 30 second piece of music might have four sub-subsections of 7.5 seconds each, three sub-sections of 10 seconds, or five subsections of 4, 5, 6, 7, and 8 seconds.
The above principles and considerations will be used by the system designer(s) when defining or creating transformational mappings between (i) certain allowable combinations of emotion, style and timing/spatial parameters supplied by the system user(s) to the input output subsystem B0 of the system, and (ii) certain music-theoretic parameters stored in system operating parameter tables that are loaded into subsystem B15 and used during the automated music composition and generation system of the present invention.
Transforming Musical Experience Parameters into Probabilistic-Based System Operating Parameters Maintained in the Parameter Tables of Subsystem B11
There is a strong relationship between emotion and style descriptors and chord length. For example, Frantic music is might likely have very short chord lengths that change frequently, whereas Reflective music might have very long chord lengths that change much less frequently. The system's length tables are reflections of the cultural connection between a musical experience and/or style and the tonality in which the material is delivered.
Further, the length of each chord is dependent upon the lengths of all previous chords; the lengths of the other chords in the same measure, phrase, and sub-phrase; and the lengths of the chords that might occur in the future. Each preceding chord length determination factors into the decision for a certain chord's length, so that the second chord's length is influenced by the first chord's length, the third chord's length is influenced by the first and second chords' lengths, and so on.
The above principles and considerations will be used by the system designer(s) when defining or creating transformational mappings between (i) certain allowable combinations of emotion, style and timing/spatial parameters supplied by the system user(s) to the input output subsystem B0 of the system, and (ii) certain music-theoretic parameters stored in system operating parameter tables that are loaded into subsystem B11 and used during the automated music composition and generation system of the present invention.
Transforming Musical Experience Parameters into Probabilistic-Based System Operating Parameters Maintained in the Parameter Tables of Subsystem B17
There is a strong relationship between Emotion and style descriptors and the initial chord. For example, a traditional piece of music might start with a Root Note equal to the key of the piece of music, whereas a piece of music that is more outside the box might start with a Root Note specifically not equal to the key of the piece.
Once a root note is selected, the function of the chord must be determined. Most often, the function of a chord is that which would occur if a triad was created in a diatonic scale of the key and tonality chosen. For example, a C chord in C Major would often function as a I chord and G chord in C Major would often function as a V chord. Once the function of a chord is determined, the specific chord notes are designated. For example, once a C chord is determined to function as a I chord, then the notes are determined to be C E G, and when a D chord is determined to function as a ii chord, then the notes are determined to be D F A.
The initial chord root note of a piece of music is based on the Emotion and style descriptor inputs to the system. Musical canon has created a cultural expectation for certain initial root notes to appear in different types of music. For example, Pop music often starts with a Root of 0, of in the key of C Major, a root of C. Once an initial root note is selected, the function of the chord that will contain the initial root note must be decided. In the key of C Major, a root note of C might reasonably have either a major or minor triad built upon the root. This would result in either a functionality of an “I” major chord or an “i” minor chord. Further, the “I” major chord might actually function as a “V/V” Major chord, in which, though it sounds identical to an “I” major chord, it functions differently and with different intent. Once this function is decided, the initial chord is now known, as the function of a chord informs the system of the notes that will make up the chord. For example, any “I” major triad will be comprised of the Root, Third, and Fifth notes of the scale, or in the key of C Major, a C major triad would be comprised of the notes C, E, and G.
The above principles and considerations will be used by the system designer(s) when defining or creating transformational mappings between (i) certain allowable combinations of emotion, style and timing/spatial parameters supplied by the system user(s) to the input output subsystem B0 of the system, and (ii) certain music-theoretic parameters stored in system operating parameter tables that are loaded into subsystem B17 and used during the automated music composition and generation system of the present invention.
Transforming Musical Experience Parameters into Probabilistic-Based System Operating Parameters Maintained in the Parameter Tables of Subsystem B19
There is a strong relationship between Emotion and style descriptors and the chord progressions. For example, a Pop piece of music might have a sub-phrase chord progression of C A F G, whereas a Gospel piece of music might have a sub-phrase chord progression of C F C F.
Further, the chord root of the progression is dependent upon the chord roots of all previous chords; the chord roots of the other chords in the same measure, phrase, and sub-phrase; and the chord roots of the chords that might occur in the future. Each preceding chord root determination factors into the decision for a certain chord's root, so that the second chord's root is influenced by the first chord's root, the third chord's root is influenced by the first and second chords' roots, and so on.
Once a chord's root is determined, the function of the chord is determined as described above. The function of a chord will then directly affect the chord root table to alter the default landscape of what chord roots might be selected in the future. For example, a C major chord in the key of C major functioning as a I chord will follow the default landscape, whereas a C major chord in the key of C major functioning as a V/IV chord will follow an altered landscape that guides the next chord to likely be a IV chord (or reasonably substitution or alteration).
Additionally, an upcoming chord's position in the piece of music, phrase, sub-phrase, and measure affects the default landscape of what chord roots might be selected in the future. For example a chord previous to a downbeat at the end of a phrase might ensure that the subsequent chord be a I chord or other chord that accurately resolves the chord progression.
Based on the cultural canon of music heretofore, Emotion and style descriptors may suggest or be well represented by certain connections or progressions of chords in a piece of music. To decide what chord should be selected next, the subsequent chord root is first decided, in a manner similar to that of B17. For each possible originating chord root, probabilities have been established to each possible subsequent chord root, and these probabilities are specifically based on the Emotion and style descriptors selected by the user.
Next, and also in a similar manner to that of B17, the function of a chord is selected. The function of the chord will affect what chords are likely to follow, and so the Chord Function Root Modifier Table provides for changes to the probabilities of the Chord Root Table based on which function is selected. In this manner, the Chord Function will directly affect which Chord Root is selected next.
Next, the position in time and space of a chord is considered, as this factor has a strong relationship with which chord root notes are selected. Based on the upcoming beat in the measure for which a chord will be selected, the chord root note table parameters are further modified. This cycle replays again and again until all chords have been selected for a piece of music.
The above principles and considerations will be used by the system designer(s) when defining or creating transformational mappings between (i) certain allowable combinations of emotion, style and timing/spatial parameters supplied by the system user(s) to the input output subsystem B0 of the system, and (ii) certain music-theoretic parameters stored in system operating parameter tables that are loaded into subsystem B19 and used during the automated music composition and generation system of the present invention.
There is a strong relationship between Emotion and style descriptors and the chord progressions. For example, a Pop piece of music might have a sub-phrase chord progression of C A F G, whereas a Gospel piece of music might have a sub-phrase chord progression of C F C F.
Further, the chord root of the progression is dependent upon the chord roots of all previous chords; the chord roots of the other chords in the same measure, phrase, and sub-phrase; and the chord roots of the chords that might occur in the future. Each preceding chord root determination factors into the decision for a certain chord's root, so that the second chord's root is influenced by the first chord's root, the third chord's root is influenced by the first and second chords' roots, and so on.
Once a chord's root is determined, the function of the chord is determined as described above. The function of a chord will then directly affect the chord root table to alter the default landscape of what chord roots might be selected in the future. For example, a C major chord in the key of C major functioning as a I chord will follow the default landscape, whereas a C major chord in the key of C major functioning as a V/IV chord will follow an altered landscape that guides the next chord to likely be a IV chord (or reasonably substitution or alteration).
Additionally, an upcoming chord's position in the piece of music, phrase, sub-phrase, and measure affects the default landscape of what chord roots might be selected in the future. For example a chord previous to a downbeat at the end of a phrase might ensure that the subsequent chord be a I chord or other chord that accurately resolves the chord progression.
Transforming Musical Experience Parameters into Probabilistic-Based System Operating Parameters Maintained in the Parameter Tables of Subsystem B20
There is a strong relationship between Experience (i.e. Emotion) and Style descriptors and the chord inversions. For example, a Rock piece of music might have chord inversions of predominantly tonics, whereas a Classical piece of music might have chord inversions consisting of much more diverse mix of tonics, first inversions, and second inversions.
The inversion of an initial chord is determined. Moving forward, all previous inversion determinations affect all future ones. An upcoming chord's inversion in the piece of music, phrase, sub-phrase, and measure affects the default landscape of what chord inversions might be selected in the future.
The above principles and considerations will be used by the system designer(s) when defining or creating transformational mappings between (i) certain allowable combinations of emotion, style and timing/spatial parameters supplied by the system user(s) to the input output subsystem B0 of the system, and (ii) certain music-theoretic parameters stored in system operating parameter tables that are loaded into subsystem B20 and used during the automated music composition and generation system of the present invention.
Transforming Musical Experience Parameters into Probabilistic-Based System Operating Parameters Maintained in the Parameter Tables of Subsystem B25
There is a strong relationship between Emotion and style descriptors and melody length. For example, a Classical piece of music might have a long melody length (that is appropriate for the longer forms of classical music), whereas a Pop piece of music might have a shorter melody length (that is appropriate for the shorter forms of pop music). One important consideration for the melody length is determining where in a sub-phrase the melody starts. The later in a sub-phrase that the melody starts, the shorter it has the potential to be.
Further, melody sub-phrase length may be unrelated to the emotion and style descriptor inputs and solely in existence to line up the measures and/or beats of the music with certain timing requests. For example, if a piece of music needs to accent a moment in the piece that would otherwise occur somewhere in the middle of a sub-phrase, beginning the melody at this place might then create more musical accent that otherwise would require additional piece manipulation to create.
Melody Sub-phrase lengths are determined based on the Music Emotion and style descriptors provided by the user. The amount, length, and probability of Melody Sub-phrase lengths are dependent on the Piece length, unique sub-phrases, phrase lengths, and on the knowledge of which combinations of the previously mentioned characteristics best fit together when creating a piece of music.
The greater amount of melody sub-phrases, the less likely each is to have a very large length. And the fewer amount of melody sub-phrases, the more likely each is to have a very large length.
Melody Sub-phrases also have to fit within the length of a piece of music and a specific phrase, so as certain melody sub-phrases are decided, future melody sub-phrase decisions and related parameters might be modified to reflect the remaining length that is available.
Melody Sub-phrases might also be structured around user-requested timing information, so that the music naturally fits the user's request. For example, if a user requests a change in the music that happens to be 3 measures into the piece, the first melody sub-phrase length might be three measures long, caused by a complete 100% probability of the melody sub-phrase length being two measures long.
The above principles and considerations will be used by the system designer(s) when defining or creating transformational mappings between (i) certain allowable combinations of emotion, style and timing/spatial parameters supplied by the system user(s) to the input output subsystem B0 of the system, and (ii) certain music-theoretic parameters stored in system operating parameter tables that are loaded into subsystem B25 and used during the automated music composition and generation system of the present invention.
Transforming Musical Experience Parameters into Probabilistic-Based System Operating Parameters Maintained in Subsystem B26
There is a strong relationship between Emotion and style descriptors and melody note rhythm. For example, Frantic music is likely to have very short melody note rhythms that change frequently, whereas Reflective music might have very long chord lengths that change much less frequently. The system's rhythm tables are reflections of the cultural connection between a musical experience and/or style and the tonality in which the material is delivered.
Further, the rhythm of each melody note is dependent upon the rhythms of all previous melody notes; the rhythms of the other melody notes in the same measure, phrase, and sub-phrase; and the melody rhythms of the melody notes that might occur in the future. Each preceding melody notes rhythm determination factors into the decision for a certain melody note's rhythm, so that the second melody note's rhythm is influenced by the first melody note's rhythm, the third melody note's rhythm is influenced by the first and second melody notes' rhythms, and so on.
Further, the length of each melody note is dependent upon the lengths of all previous melody notes; the lengths of the other melody notes in the same measure, phrase, and sub-phrase; and the lengths of the melody notes that might occur in the future. Each preceding melody note length determination factors into the decision for a certain melody note's length, so that the second melody note's length is influenced by the first melody note's length, the third melody note's length is influenced by the first and second melody notes' lengths, and so on.
The above principles and considerations will be used by the system designer(s) when defining or creating transformational mappings between (i) certain allowable combinations of emotion, style and timing/spatial parameters supplied by the system user(s) to the input output subsystem B0 of the system, and (ii) certain music-theoretic parameters stored in system operating parameter tables that are loaded into subsystem B26 and used during the automated music composition and generation system of the present invention.
Transforming Musical Experience Parameters into Probabilistic-Based System Operating Parameters Maintained in the Parameter Tables of Subsystem B29
There is a strong relationship between Emotion and style descriptors and the pitch. For example, a Pop piece of music might have pitches that are largely diatonic, whereas an Avant-garde piece of music might have pitches that are agnostic to their relationship with the piece's key or even each other.
Each pitch of a sub-phrase is dependent upon the pitches of all previous notes; the pitches of the other notes in the same measure, phrase, and sub-phrase; and the pitches of the notes that might occur in the future. Each preceding pitch determination factors into the decision for a certain note's pitch, so that the second note's pitch is influenced by the first note's pitch, the third note's pitch is influenced by the first and second notes' pitches, and so on.
Additionally, the chord underlying the pitch being selected affects the landscape of possible pitch options. For example, during the time that a C Major chord occurs, consisting of notes C E G, the note pitch would be more likely to select a note from this chord than during the time that a different chord occurs.
Also, the notes' pitches are encourage to change direction, from either ascending or descending paths, and leap from one note to another, rather than continuing in a step-wise manner.
The above principles and considerations will be used by the system designer(s) when defining or creating transformational mappings between (i) certain allowable combinations of emotion, style and timing/spatial parameters supplied by the system user(s) to the input output subsystem B0 of the system, and (ii) certain music-theoretic parameters stored in system operating parameter tables that are loaded into subsystem B29 and used during the automated music composition and generation system of the present invention.

There is a strong relationship between Emotion and style descriptors and the pitch frequency. For example, a Moody piece of music might have pitches that are lower in the frequency range, whereas an Energetic piece of music might have pitches that are higher in the frequency range.
Each pitch frequency of a sub-phrase is dependent upon the pitch frequencies of all previous notes; the pitch frequencies of the other notes in the same measure, phrase, and sub-phrase; and the pitch frequencies of the notes that might occur in the future. Each preceding pitch frequency determination factors into the decision for a certain note's pitch frequency, so that the second note's pitch frequency is influenced by the first note's pitch frequency, the third note's pitch frequency is influenced by the first and second notes' pitch frequencies, and so on.
The above principles and considerations will be used by the system designer(s) when defining or creating transformational mappings between (i) certain allowable combinations of emotion, style and timing/spatial parameters supplied by the system user(s) to the input output subsystem B0 of the system, and (ii) certain music-theoretic parameters stored in system operating parameter tables that are loaded into subsystem B30 and used during the automated music composition and generation system of the present invention.

There is a strong relationship between Emotion and style descriptors and the instruments that play the music. For example, a Rock piece of music might have guitars, drums, and keyboards, whereas a Classical piece of music might have strings, woodwinds, and brass.
There is a strong relationship between Emotion and style descriptors and the instrumentation of a musical piece or a section of a musical piece. For example, Pop music might be likely have Guitars, Basses, Keyboards, and Percussion, whereas Classical music might have Strings, Brass, and Woodwinds. Further different types of Pop music or different Musical Emotion and style descriptors might have different types of instruments within each instrument category, so that Driving Pop music might have electric guitars, whereas Calm Pop music might have acoustic guitars.
Further, while the piece instrumentation will contain all instruments within the piece, all instruments might not always play together all of the time.
The above principles and considerations will be used by the system designer(s) when defining or creating transformational mappings between (i) certain allowable combinations of emotion, style and timing/spatial parameters supplied by the system user(s) to the input output subsystem B0 of the system, and (ii) certain music-theoretic parameters stored in system operating parameter tables that are loaded into subsystem B39 and used during the automated music composition and generation system of the present invention.
Transforming Musical Experience Parameters that Populate System Operating Parameter Tables in the Parameter Tables of Subsystem B31
There is a strong relationship between Emotion and style descriptors and the instruments that play the music. For example, a piece of music orchestrated in a Rock style might have a sound completely different than the same piece of music orchestrated in a Classical style.
Further, the orchestration of the musical piece may be unrelated to the emotion and style descriptor inputs and solely in existence to effect timing requests. For example, if a piece of music needs to accent a certain moment, regardless of the orchestration thus far, a loud crashing percussion instrument such as a cymbal might successfully accomplish this timing request, lending itself to a more musical orchestration in line with the user requests.
It is important in orchestration to create a clear hierarchy of each instrument and instrument groups' function in a piece or section of music, as the orchestration of an instrument functioning as the primary melodic instrument might be very different than if it is functioning as an accompaniment. Once the function of an instrument is determined, the manner in which the instrument plays can be determined. For example, a piano accompaniment in a Waltz (in a ¾ time signature) might have the Left Hand play every downbeat and the Right Hand play every second and third beat. Once the manner in which an instrument is going to play is determined, the specifics, including the note lengths, can be determined. For example, continuing the previous example, if the Left Hand of the piano plays on the downbeat, it might play for an eighth note or a half note.
Each note length is dependent upon the note lengths of all previous notes; the note lengths of the other notes in the same measure, phrase, and sub-phrase; and the note lengths of the notes that might occur in the future. Each preceding note length determination factors into the decision for a certain note's length, so that the second note's length is influenced by the first note's length, the third note's length is influenced by the first and second notes' lengths, and so on.
The dynamics of each instrument should also be determined to create an effective orchestration. The dynamics of an instrument's performance will be ever changing, but are often determined by guiding indications that follow the classical music theory cannon.
The above principles and considerations will be used by the system designer(s) when defining or creating transformational mappings between (i) certain allowable combinations of emotion, style and timing/spatial parameters supplied by the system user(s) to the input output subsystem B0 of the system, and (ii) certain music-theoretic parameters stored in system operating parameter tables that are loaded into subsystem B31 and used during the automated music composition and generation system of the present invention.
Transforming Musical Experience Parameters into Probabilistic-Based System Operating Parameters Maintained in the Parameter Tables of Subsystem B32
There is a strong relationship between Emotion and style descriptors and the controller code information that informs how the music is played. For example, a piece of music orchestrated in a Rock style might have a heavy dose of delay and reverb, whereas a Vocalist might incorporate tremolo into the performance.
Further, the controller code information of the musical piece may be unrelated to the emotion and style descriptor inputs and solely in existence to effect timing requests. For example, if a piece of music needs to accent a certain moment, regardless of the controller code information thus far, a change in the controller code information, such as moving from a consistent delay to no delay at all, might successfully accomplish this timing request, lending itself to a more musical orchestration in line with the user requests.
The above principles and considerations will be used by the system designer(s) when defining or creating transformational mappings between (i) certain allowable combinations of emotion, style and timing/spatial parameters supplied by the system user(s) to the input output subsystem B0 of the system, and (ii) certain music-theoretic parameters stored in system operating parameter tables that are loaded into subsystem B32 and used during the automated music composition and generation system of the present invention.
System Network Tools for Creating and Managing Parameters Configurations within the Parameter Transformation Engine Subsystem B51 of the Automated Music Composition and Generation System of the Present Invention
These parameter mapping configuration tools are used to configure the Parameter Transformation Engine Subsystem B52 during the system design stage, and thereby program define or set probability parameters in the sets of parameter tables of the system for various possible combinations of system user inputs described herein. More particularly, these system designer tools enable the system designer(s) to define probabilistic relationships between system user selected sets of emotion/style/timing parameters and the music-theoretic system operating parameters (SOP) in the parameter tables that are ultimately distributed to and loaded into the subsystems, prior to execution of the automated music composition and generation process. Such upfront parameter mapping configurations by the system designer imposes constraints on system operation, and the parameter selection mechanisms employed within each subsystem (e.g. random number generator, or user-supplied lyrical or melodic input data sets) used by each subsystem to make local decisions on how a particular parts of a piece of music will be ultimately composed and generated by the system during the automated music composition and generation process of the present invention.

In general, the number of possible combinations of probability-based SOP tables that will need to be generated for configuring the Parameter Transformation Engine Subsystem B51 with parameter-transformational capacity, will be rather large, and will be dependent on the size of possible emotion-type and style-type musical experience descriptors that may be selected by system users for any given system design deployed in accordance with the principles of the present invention. The scale of such possible combinations has been discussed and modeled hereinabove.

Using Lyrical and/or Musical Input to Influence the Configuration of the Probability-Based System Operating Parameter Tables Generated in the Parameter Transformation Engine Subsystem B51, and Alternative Methods of Selecting Parameter Values from Probability-Based System Operating Parameter Tables Employed in the Various Subsystems Employed in the System of the Present Invention
Throughout the illustrative embodiments, a random number generator is shown being used to select parameter values from the various probability-based music-theoretic system operating parameter tables employed in the various subsystems of the automated music composition and generation system of the present invention. It is understood, however, that non-random parameter value selection mechanisms can be used during the automated music composition and generation process. Such mechanisms can be realized globally within the Parameter Transformation Engine Subsystem B51, or locally within each Subsystem employing probability-based parameter tables.
In the case of global methods, the Parameter Transformation Engine Subsystem B51 (or other dedicated subsystem) can automatically adjust the parameter value weights of certain parameter tables shown in FIGS. 27B3A through 27B3C in response to pitch information automatically extracted from system user supplied lyrical input or musical input (e.g. humming or whistling of a tune) by the pitch and rhythm extraction subsystem B2. In such global methods, a random number generator can be used to select parameter values from the lyrically/musically-skewed parameter tables, or alternative parameter mechanisms such as the lyrical/musical-responsive parameter value section mechanism described below in connection with local methods of implementation.
In the case of local methods, the Real-Time Pitch Event Analyzing Subsystem B52 employed in the system shown in
In either method, global or local, from a set of lyrics and/or other input medium(s) (e.g. humming, whistling, tapping etc.), the system of the present invention may use, for example, the Real-Time Pitch Event Analyzing Subsystem B52 in
It will be helpful to discuss a few types of pitch and rhythmic information which, when extracted from lyrical/musical input by the system user, would typically influence the selection of parameter values in certain parameter tables using a lyrically, or musically, responsive parameter selection mechanism being proposed in this alternative embodiments of the present invention. These case examples will apply to both the global and local methods of implementation discussed above.
For example, in the event that the input material consists of a high frequency of short and fast rhythmic material, then the rhythmic-related subsystems (i.e. B2, B3, B4, B9, B15, B11, B25, and B26 illustrated in FIGS. 27B3A through 27BC) might be more likely to select 16th and 8th note rhythmic values or other values in the parameter tables that the input material might influence. Consider the following rhythm-related examples: (i) a system user singing a melody with fast and short rhythmic material might cause the probabilities in Subsystem B26 to change and heavily emphasize the sixteenth note and eighth note options; (ii) a system user singing a waltz with a repetitive pattern of 3 equal rhythms might cause the probabilities in Subsystem B4 to change and heavily emphasize the ¾ or 6/8 meter options; (iii) a system user singing a song that follows a Verse Chorus Verse form might cause the probabilities in Subsystem B9 to change and heavily emphasize the ABA form option; (iv) a system user singing a melody with a very fast cadence might cause the probabilities in Subsystem B3 to change and heavily emphasize the faster tempo options; and (v) a system user singing a melody with a slowly changing underlying implied harmonic progression might cause the probabilities in Subsystem B11 to change and heavily emphasize the longer chord length options.
In the event that the input material consists of pitches that comprise a minor key, then the pitch-related subsystems (i.e. B5, B7, B17, B19, B20, B27, B29 and B30 illustrated in FIGS. 27B3A, 27B3B and 27B3C) might be more likely to select a minor key(s) and related minor chords and chord progressions or other values that the inputted material might influence. Consider the following pitch-related examples: (i) a system user singing a melody that follows a minor tonality might cause the probabilities in Subsystem B7 to change and heavily emphasize the Minor tonality options; (ii) a system user singing a melody that centers around the pitch D might cause the probabilities in Subsystem B27 to change and heavily emphasize the D pitch option; (iii) a system user singing a melody that follows an underlying implied harmonic progression centered around E might cause the probabilities in Subsystem B17 to change and heavily emphasize the E root note options; (iv) a system user singing a melody that follows a low pitch range might cause the probabilities in the parameter tables in Subsystem B30 to change and heavily emphasize the lower pitch octave options; and (v) a system user singing a melody that follows an underlying implied harmonic progression centered around the pitches D F# and A might cause the probabilities in Subsystem B5 to change and heavily emphasize the key of D option.
In the event that the system user input material follows a particular style or employs particular the controller code options, then the instrumentation subsystems B38 and B39 and controller code subsystem B32 illustrated in FIGS. 27B3A, 27B3B and 27B3C, might be more likely to select certain instruments and/or particular controller code options, respectively. Consider the following examples: (i) a system user singing a melody that follows a Pop style might cause the probabilities in Subsystem B39 to change and heavily emphasize the pop instrument options; and (ii) a system user singing a melody that imitates a delay effect might cause the probabilities in Subsystem B32 to change and heavily emphasis the delay and related controller code options.
Also, in the event that the system user input material follows or imitates particular instruments, and/or methods of playing the same, then the orchestration subsystem B31 illustrated in FIGS. 27B3A, 27B3B and 27B3C might be more likely to select certain orchestration options. Consider the following orchestration-related examples: (i) a system user singing a melody with imitated musical performance(s) of an instrument(s) might cause the probabilities in Subsystem B31 to change and heavily emphasize the orchestration of the piece to reflect the user input; (ii) if a system user is singing an arpeggiated melody, the subsystem B31 might heavily emphasize an arpeggiated or similar orchestration of the piece; (iii) a system user singing a melody with imitated instruments performing different musical functions might cause the probabilities in Subsystem B31 to change and heavily emphasize the musical function selections related to each instrument as imitated by the system user; and (iv) if a system user is alternating between singing a melody in the style of violin and an accompaniment in the style of a guitar, then the Subsystem B31 might heavily emphasize these musical functions for the related or similar instrument(s) of the piece.
In this illustrative embodiment, shown in
As will explained further detail herein, lyrics when applied to particular scenes by the system user will be processed in different ways, depending on whether the lyrics are typed, spoken or sung, so as to extract vowel formants that allow for the automated detection of pitch events, along a time-line, supporting an initial or starting melodic structure. Such pitch events can be used to inform and constrain the musical experience descriptor and timing/spatial parameters which the Parameter Transformation Engine Subsystem B51 uses to generate system operating parameters based on the complete set of the musical experience descriptors, including timing parameters and lyrics, that may be provided to the system interface subsystem B0 as input by the system user.
As illustrated in
In general, the automatic or automated music composition and generation system shown in
For purpose of illustration, the digital circuitry implementation of the system is shown as an architecture of components configured around SOC or like digital integrated circuits. As shown, the system comprises the various components, comprising: a SOC sub-architecture including a multi-core CPU, a multi-core GPU, program memory (DRAM), and a video memory (VRAM); a hard drive (SATA); a LCD/touch-screen display panel; a microphone/speaker; a keyboard; WIFI/Bluetooth network adapters; pitch recognition module/board; and power supply and distribution circuitry; all being integrated around a system bus architecture and supporting controller chips, as shown.
The primary function of the multi-core CPU is to carry out program instructions loaded into program memory (e.g. micro-code), while the multi-core GPU will typically receive and execute graphics instructions from the multi-core CPU, although it is possible for both the multi-core CPU and GPU to be realized as a hybrid multi-core CPU/GPU chip where both program and graphics instructions can be implemented within a single IC device, wherein both computing and graphics pipelines are supported, as well as interface circuitry for the LCD/touch-screen display panel, microphone/speaker, keyboard or keypad device, as well as WIFI/Bluetooth (BT) network adapters and the pitch recognition module/circuitry. The purpose of the LCD/touch-screen display panel, microphone/speaker, keyboard or keypad device, as well as WIFI/Bluetooth (BT) network adapters and the pitch recognition module/circuitry will be to support and implement the functions supported by the system interface subsystem B0, but may be used for implementing other subsystems as well employed in the system shown in

The Automated Music Composition and Generation Engine of the present invention will have use in many application beyond those described this invention disclosure.
For example, consider the use case where the system is used to provide indefinitely lasting music or hold music (i.e. streaming music). In this application, the system will be used to create unique music of definite or indefinite length. The system can be configured to convey a set of musical experiences and styles and can react to real-time audio, visual, or textual inputs to modify the music and, by changing the music, work to bring the audio, visual, or textual inputs in line with the desired programmed musical experiences and styles. For example, the system might be used in Hold Music to calm a customer, in a retail store to induce feelings of urgency and need (to further drive sales), or in contextual advertising to better align the music of the advertising with each individual consumer of the content.
Another use case would be where the system is used to provide live scored music in virtual reality or other social environments, real or imaginary. Here, the system can be configured to convey a set of musical experiences and styles and can react to real-time audio, visual, or textual inputs. In this manner, the system will be able to “live score” content experiences that do well with a certain level of flexibility in the experience constraints. For example, in a video game, where there are often many different manners in which to play the game and courses by which to advance, the system would be able to accurately create music for the game as it is played, instead of (the traditional method of) relying on pre-created music that loops until certain trigger points are met. The system would also serve well in virtual reality and mixed reality simulations and experiences.
The present invention has been described in great detail with reference to the above illustrative embodiments. It is understood, however, that numerous modifications will readily occur to those with ordinary skill in the art having had the benefit of reading the present invention disclosure.
In alternative embodiments, the automatic music composition and generation system of the present invention can be modified to support the input of conventionally notated musical information such as, for example, notes, chords, pitch, melodies, rhythm, tempo and other qualifies of music, into the system input interface for processing and use in conjunction with other musical experience descriptors provided the system user, in accordance with the principles of the present invention.
For example, in alternative embodiments of the present invention described hereinabove, the system can be realized a stand-alone appliances, instruments, embedded systems, enterprise-level systems, distributed systems, and as an application embedded within a social communication network, email communication network, SMS messaging network, telecommunication system, and the like. Such alternative system configurations will depend on particular end-user applications and target markets for products and services using the principles and technologies of the present invention.
While the preferred embodiments disclosed herein have taught the use of virtual-instrument music synthesis to generate acoustically-realized notes, chords, rhythms and other events specified in automated music compositions, in stark contrast with stringing together music loops in a manner characteristic of prior art systems, it is understood that the automated music composition and generation system of the present invention can be modified to adapt the musical score representations generated by the system, and convert this level of system output into MIDI control signals to drive and control one or more groups of MIDI-based musical instruments to produce the automatically composed music for the enjoyment of others. Such automated music composition and generation systems could drive entire groups of MIDI-controlled instruments such as displayed during Pat Metheny's 2010 Orchestrion Project. Such automated music composition and generation systems could be made available in homes and commercial environments as an alternative to commercially available PIANODISC® and YAMAHA® MIDI-based music generation systems. Such alternative embodiments of the present inventions are embraced by the systems and models disclosed herein and fall within the scope and spirit of the present invention.
These and all other such modifications and variations are deemed to be within the scope and spirit of the present invention as defined by the accompanying Claims to Invention.
