1. Field of the Invention
The present invention relates generally to brass instruments and, more particularly, to brass instruments with improved tonal characteristics.
2. Description of the Related Art
Brass instruments (labrosones) are generally musical instruments in which the tone is produced by vibration of the lips as the player blows into a resonator or mouthpiece. Brass instruments differ from woodwinds in that woodwind instruments are generally those in which sound is produced by blowing through a mouthpiece against an edge or a vibrating reed, and which the pitch is varied by opening or closing holes in the body of the instrument. Brass instruments have various general ways of varying the tone. In one class of brass instruments, the tone is varied only by increasing or decreasing the rate of vibrations of the lips. In such instruments, the only available tones are those in the harmonic series of the instrument. On example of such an instrument is the bugle. In a third class of brass instruments, the tone may be varied by changing the length of the tubing using a slide. One example of such an instrument is the trombone. In yet another class of brass instruments, the tone may be varied by covering and/or uncovering holes along the body of the instrument. One example of such an instrument is the cornetto. Brass instrument may also vary tone by using a combination of the above techniques.
In another class, the tone may be varied by changing the length of the tubing of the instrument using valves. One example of such an instrument is the trumpet. The general configuration of the various instruments categorized as trumpets has not changed since the trumpet's inception. The trumpet generally includes a mouthpiece in fluid communication with a plurality of valves through a series of curved pipes with each valve controllable by a finger button. Air blown through the mouthpiece flows through the valves and exits through the bell. Trumpets can have from one to three valves to produce many different pitches.
Producing a correct pitch in a brass instrument may be difficult. Often when a single note is played, the instrument produces not only the note, but a series of overtones as well. If the overtones do not have frequencies at the proper levels, the overtones reduce the sound quality of the note played. Often in brass instruments, the overtones deviate from the desired frequencies. Brass instruments are often designed such that particular positions of valves, slides, and the like produce different notes. For example, a trumpet is designed such that the tones of a trumpet are played by depressing valves to vary the length of the tubing. This technique is generally called “slotting,” that is, the technique of depressing certain keys to generate a particular tone. A particular note is slotted by depressing the correct valve, or combination of valves. One difficulty in playing a valved brass instrument is that the overtones may not be slotted correctly. That is, though the instrument may be slotted to play the fundamental note correctly, the player may be required to vary the method of buzzing into the instrument to bring the overtones into a correct range, thereby improving the tonal characteristics of the tone played. Thus it remains difficult to play a valved brass instrument because the player is required to correct the pitch due to the overtones deviating from the desired frequencies.
It has been documented that many people, especially those who have been musically trained, are capable of detecting a difference in frequency between two separate sounds which is as little as 2 Hz. Thus, even a slight improvement in one or more of the overtones of a particular note played can have a significant impact on the tonal characteristics of the overall sound of the brass instrument.
Accordingly, attempts have been made to improve, among other things, the tonal characteristics of brass instruments. Various disclosures include brass instruments. For example, U.S. Pat. No. 6,664,456 to Momchilovich discloses resilient material and/or rubber O-rings that are placed at various predetermined locations to reduce unwanted sympathetic vibrations on musical instruments and firearms. This may improve the performance and sound of musical instruments and make them easier to play. The resilient material disclosed in this patent includes rubber O-rings.
Further, U.S. Pat. Nos. 5,965,832 and 5,644,095 to Davidson disclose an improvement to the tone and responsiveness of brass instruments that is achieved by holding pre-shaped pieces of damping material, preferably a waxy, hot-melt adhesive, pressed against surfaces of the instrument tubing sections such as valve casings and tubing sections at particular locations, to reduce sympathetic vibrations of the instrument structure.
U.S. Pat. No. 59,204 to Fiske discloses the interposing of rubber or another suitable elastic substance between the attachments of the main pipe with the bell of a wind instrument.
U.S. Pat. No. 3,635,117 to Nagao discloses a ring fixing structure for a woodwind musical instrument. Rings are fixed around the elongated hollow bodies of the woodwind musical instrument, such as their joints and bell edge for reinforcing and ornamental purposes, grooves are formed, respectively, in opposite portions of the elongated hollow bodies and rings, and an adhesive of hot-melt-type is inserted and disposed in the grooves.
Thus, there exists a need to improve the response (i.e., ease of slotting for achieving a correct tone) of slotted brass instruments. Further, there exists a need to improve the tonal characteristics of brass instruments. In addition, there exists a need to improve tonal consistency and evenness throughout the range of notes playable on a particular brass instrument.
There is also a need to improve the tone quality, focus, clarity, character, warmth, centering and depth of sound produced by a brass instrument.

Turning now to
The tonal material may be any material that alters any of the tonal characteristics. Typically used on keys of brass instruments such as trumpets is mother of pearl. Mother of pearl, also known as nacre or sadaf, is calcium carbonate platelets with elastic biopolymers (such as chitin, lustrin, or the like). Mother of pearl has a Mohs hardness of from about 2.5 to about 4.5. The present invention envisions placing a tonal material on the body of the instrument. In one example, mother of pearl may be placed on the body of the instrument. The tonal materials in another embodiment of the present invention, typically have a Mohs hardness of greater than that of mother of pearl. The tonal materials of the present invention may also be more dense than mother of pearl. Some examples of tonal materials, (and the mohs hardness of some of them) that may be used include semi-precious stones such as garnet (6-7), jasper (6.5-7.5), agate (6.5-7), aventurine (6.5), carnelian (6.5-7), citrine (7), fluorite (4), hematite (5), malachite (3.5-4), obsidian (5-7), onyx (7), tiger's eye (7), turquoise (5-6), unakite (6-7), moonstone (6-6.5), peridot (6.5), jade (6.5-7), alexandrite (7-7.5), amethyst (7), chalcedony (7), quartz (7), aquamarine (7.5-8), lolite (7-7.5), rhodolite (7-7.5), opal (5-6), topaz (8), tourmaline (7-7.5), tanzanite (6.5); and precious stones such as diamond (10), emerald (8), sapphire (9), Ceylon sapphire (9), ruby (9), and the like; and other materials such as pumice (6), tungsten carbide (9), steel (6.5), silicon carbide (9), boron carbide (9), strontium titanate (6), emery (7-9), crystolon (9), corundum (9), and the like. In one embodiment, the tonal material is one with a Mohs hardness of at least 6.
In order to demonstrate the practice of the present invention, the following examples have been prepared. The examples should not, however, be viewed as limiting the scope of the invention. The claims will serve to define the invention.
The addition of stones to the trumpet has a dramatic improvement in the various tonal characteristics of the trumpet. In order to demonstrate the improvements in the sound emanating from a trumpet according to the present invention, several tests were performed. The tests results are summarized in Tables I and II. The testing involved using a 35670A Hewlett Packard Spectrum Analyzer with sound being recorded through calibrated condenser microphones made by ACO, ¼ inch model 7012 and ½ inch model 7017. The frequency range of the Spectrum Analyzer was set at 200 Hz to 6.6 kHz to an octave above that—concert B flat (472 Hz), and then the frequency range was changed from 200 Hz to 13 kHz for concert C (520 Hz). At these frequency ranges, the Spectrum Analyzer could measure and record the fundamental tone and the next 9 overtones or harmonics. Sound was measured in Hz or cycles per second of each fundamental tone and overtones as well as the volume amplitude of each fundamental tones and overtones.
The tests were conducted with the results recorded while playing an ascending scale starting at concert B flat (232 Hz and ending at concert C (520 Hz).
In order to control deviation between tests, each test was conducted using one trumpet by one professional trumpet player and using the same mouthpiece and playing position. Each note was played with a stone (as the tonal material) attached to the trumpet to the return side near the third valve, as illustrated in
As is shown in Table I, the frequency of each overtone, 1st through 9th, is recorded for each of the two trumpet configurations (W meaning with stone, W/O meaning without stone), as well as the difference between the frequency with the stone and the frequency without the stone. At the bottom of Table I, the average difference of the frequencies played for each overtone is provided. All frequencies are in Hz. While the first overtone had virtually no measurable difference, each of the subsequent overtones showed a significant drop in frequency between the trumpet with stone and without, from 4 Hz at the third overtone to 64 Hz at the ninth.
It was further found that the second through sixth overtones actually have a greater amplitude than the fundamental frequency. As such, a change in frequency of one of the first through sixth overtones will have a dramatic affect on the sound of the trumpet. Also, even though the seventh, eighth and ninth overtones have an amplitude that is lower than the fundamental frequency, the measurable shift in frequency (64 Hz for both the eight and ninth overtones) is clearly audible.
As previously discussed, the human ear can detect frequency deviations as little as 2 Hz. As such, the trumpet with even a single stone exhibits a dramatic improvement in sound as each of the second through ninth overtone frequencies are diminished. The result is that the trumpet overtones become less sharp thus dramatically improving the player's ability to slot the desired pitch. It should also be noted, that the higher the overtones, the less effect they may have on the perception of the tonal characteristics. That is, if the 19th overtone deviates by 2 Hz from standard, the tonal characteristics will not be as negatively affected as if the first or second overtones deviate by 2 Hz from standard. Another aspect that affects the tonal characteristics is the relative volume of the overtones. Overtones that are at least as loud as the fundamental note played have more of an effect on tonal characteristics than do overtones that are not as loud as the fundamental note played.
As further illustrated in Table II, the amplitude in dB of each overtone, first through fifth, was recorded. In Table II is recorded the percent difference between the respective overtone and the note played with and without the stone. Further recorded is the difference the results recorded with the stone and those recorded without the stone. For example, when the C was played, the second overtone with the stone recorded a decibel level 111.15% of the note played with a stone. The second overtone decibel level without the stone was 123.76% of the note played. The difference between the two is −12.61%, meaning that the overtone of the note played with the stone exhibited a less substantial increase in decibel level than the overtone of the note played without the stone. In each such overtone, the amplitude of the overtones was decreased when a single stone was used by an average of approximately 4 to 5 percent. Because the actual amplitude of sound of each of these overtones was reduced, the sound of the fundamental note becomes more pronounced. That is, using a stone on the side of the trumpet changes the timbre of the trumpet by lowering the intensity of the overtones causing the fundamental tone to be more present. Listeners stated that this improved the tone and created a more focused and centered sound. From a players perspective, the trumpet becomes easier to slot to the desired pitch. The test data shows that the sound of the trumpet of the present invention has improved tone quality, focus, clarity, character, warmth, centering of sound and depth. Each of these improvements in the tonal characteristics of the trumpet are a result of the overtones being diminished in both frequency and amplitude to cause the trumpet to become more “true” to the note being played making it easier to play and significantly better sounding.
The stone used in the above examples had a Mohs hardness of greater than about 6. It is believed, but not meant to be limiting, that the density of the material over mother of pearl may also have an effect on the resonant properties of the trumpet that produce the results discussed above.
In summary, this application discloses in the present invention a method and design allowing for altering of the tonal characteristics of a brass instrument by attaching a tonal material on the brass instrument. The brass instrument may be any as described above. The location of attachment may be any as described above. The tonal material may be any as described above. The attachment may or may not include a housing and/or an adhesive, as described above.
It is understood that the above-described embodiments are only illustrative of the application of the principles of the present invention. The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiment is to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claim rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
For example, although the figures illustrate that the brass instrument is a trumpet or the like, it is envisioned that any brass instrument is within the bounds of this invention. Some examples of brass instruments upon which this invention may be applied include trumpets, bass trumpets, flumpets, French horns, tubas, Wagner tubas, trombones, superbones, bugles, sousaphones, mellophones, euphoniums, flugelhorns, saxhorns, cornets, cornettos, serpents, sackbuts, bazookas, horns, ophicleides, didgeridoos, shofars, conches, alphorns, cimbassos, and keyed trumpets.
Additionally, although the figures illustrate an oval-shaped tonal material, it is envisioned that any shape of tonal material that may alter any of the tonal characteristics may be used in the present invention. Some examples of shapes that may be used include oval, circular, triangular, rectangular, square, polygonal, egg-shaped, pyramidal, cubic, toroidal, and so forth.
It is also envisioned that the tonal material may be placed anywhere on the brass instrument. The tonal material may be placed where it may affect the tonal characteristics. For example, the tonal material may substantially or completely encircle a tubular member of the brass instrument. Further, the tonal material may replace a portion of the brass instrument. For example, a portion of the return side of a trumpet may be replaced by a tubular portion of tonal material such as semi-precious stone.
It should be noted that in one particular embodiment, the tonal material are naturally-occurring stones, materials and the like. In yet another particular embodiment, the hardness of the naturally occurring tonal materials is greater than that of mother-of-pearl.
Finally, it is envisioned that the components of the brass instrument may be constructed of a variety of materials. It is not necessary that the brass instrument be constructed of brass, as brass identifies a class of instrument, not the material from which it is constructed. Brass instruments may be constructed of a variety of materials, such as plastics, composites, wood, metals, alloys, crystalline structures, stone, fiber, glass, and so forth.
Thus, while the present invention has been fully described above with particularity and detail in connection with what is presently deemed to be the most practical and preferred embodiment of the invention, it will be apparent to those of ordinary skill in the art that numerous modifications, including, but not limited to, variations in size, materials, shape, form, function and manner of operation, assembly and use may be made, without departing from the principles and concepts of the invention as set forth in the claims.
In order to demonstrate the practice of the present invention, the following examples have been prepared. The examples should not, however, be viewed as limiting the scope of the invention. The claims will serve to define the invention.
