The subject matter of the present disclosure relates generally to a musical instrument, and more specifically to a percussive idiophone which may be combined with water to produce cymatic effects when struck.
Drums are percussion-based musical instruments that produce sound when struck. The sound elicited from drums and other percussive instruments is often utilized to create or contribute to the rhythmic section of musical compositions. Accordingly, drums are a central feature of many musical groups' and solo artists' musical acts. Traditionally, drums have existed as membranophones, i.e., musical instruments which produce sound primarily by way of vibrating a stretched membrane. As such, many known drums often comprise at least one membrane, commonly referred to as a “drum head” or “skin”, stretched over a hollowed shell. Often times, the drum head is secured in relation to an open end of the shell by way of a tension ring, commonly referred to as a “hoop” or “rim”, that is positioned over the drum head and which may be drawn downwardly toward the shell using one or more tension screws or other tightening mechanisms. By tightening the tension screws the drum head is stretched and the tension of the drum head is increased, thereby producing a higher pitched sound when struck. Conversely, by loosening the tension screws the drum head draws inwardly upon itself such that the tension of the drum head is decreased, thereby producing a lower pitched sound when struck. For some drums, such as djembes, the tension of a drum head may be increased or decreased by other tightening mechanisms, such as rope, however, the pitch of such drums is affected in the same manner as those with tightening screws. Accordingly, for traditional drums, the pitch of the sound emitted from a drumhead when struck is generally dependent upon the extent to which the drum head is stretched over the shell, and thus can only be altered by increasing or decreasing the tension of the drum head. In turn, as the tension of a drum head is generally manipulated by tightening or loosening the tightening mechanism of the drum, the pitch of sound elicited from the drumhead cannot be readily manipulated while the drum is being played.
A variety of non-membranophone drums, such as steel or wooden tongue drums, are known. The pitches of sound exhibited by such instruments, however, generally cannot be manipulated because the tonal elements that produce sound when struck are embedded in a fixed position within the instrument's body. U.S. Pat. No. 3,896,696 to Richard A. Water discloses a tonal percussive instrument, more colloquially referred to as a “waterphone”, that can utilize water movement to affect the pitch of the sounds produced thereby when struck or bowed. Water is generally introduced into waterphones by pouring a desired amount of water in through an elongated neck and into a resonator chamber such that the water pools at the base of the chamber. In waterphones, the resonator chamber is enclosed except for a small aperture that provides passage from the instrument's neck to the resonator chamber. As such, the water contained within the resonator chamber is not generally visible.
Cymatics is the process of making sound waves visible. In cymatics, the visualization of sound may be achieved by vibrating a surface on which a deformable medium, such as water, is disposed. As the surface vibrates, regions of the surface exhibiting maximum and minimum displacement are made visible by the deforming medium. Depending on the nature of the vibration exhibited by the surface, the deformable medium may form visually pleasing designs or patterns which, in some instances, may cause observers thereof to experience feelings of calm. Although the water utilized within waterphones may sometimes be deformed in response to vibrations created during the playing thereof, the patterns and designs resulting from such deformities are not visible due to the generally closed design of the waterphone.
New apparatuses, systems, kits, and methods for a percussive instrument that permits users to view the patterns or designs exhibited by a deformable medium contained therein and that enables users to vary the pitch of sound elicited from the instrument during the playing thereof are described herein.
In one aspect, a percussive instrument is provided. The percussive instrument generally comprises a drum body defined by a base having a peripheral wall extending upwardly therefrom and a plurality of tonal elements which may be struck or plucked to produce sound. The drum body includes an open end opposite the base to permit sound elicited from the tonal elements to escape into the surrounding environment. Each tonal element may be secured proximate to the drum body's open end and extend over the bottom surface of the drum body. To vary the frequency of vibration experienced by, and thus the pitch of sound elicited from, each tonal element when struck or plucked, the length of some or all of the tonal elements may vary. Accordingly, the lengths of the tonal elements may be selected so that each will vibrate at a predetermined frequency so that any desired scale of frequencies may be attained.
In response to being struck or plucked, the tonal elements vibrate to produce audible sound waves. Vibration of the tonal elements may cause vibration within the drum body. Liquids may be introduced into the drum body via its open end to pool on the bottom surface of the drum body. Vibration of the drum body may cause the pooled liquid to deform in accordance with such vibration, thereby producing patterns or designs within the liquid viewable to users via the open end of the drum body. As various tonal elements may vibrate at different frequencies, the vibrations experienced by the drum body, and thus patterns or designs within the pooled liquid, may also vary depending on which tonal elements are struck or plucked.
Liquid may also be introduced into the drum body to provide a secondary medium—in addition to a first medium of air—through which the sound waves emitted from the tonal elements may pass over or through. As the sound waves pass from the first medium of air to or over the second medium of liquid, refraction of the sound waves may occur causing the directional path and wavelength of the sound waves produced by the tonal elements to change. While playing the instrument, users may move the drum body to affect the pooling location of the liquid and alter the pitch of sound elicited from the tonal elements while actively playing the instrument.

Turning now to the drawings,
The instrument 100 includes a drum body 105 and a plurality of tonal elements 140. The drum body 105 is defined by a base 110 and a peripheral wall 120 extending upwardly from the base 110. In an embodiment, the drum body 105 may be integrally formed such that the base 110 and peripheral wall 120 are permanently joined together to form a single component of the instrument 100. In other embodiments, the base 110 and peripheral wall 120 may be separate components that are removably secured together to form the drum body 105. In some embodiments, the base 110 and peripheral wall 120 may each retain a generally annular shape so that the drum body 105 forms a cylinder having an open end 150 and an opposite closed end, as shown best in
As shown best in
In other embodiments, the peripheral wall 120 may be devoid of a curved portion and comprise only a straight portion 120B such that the peripheral wall 120 extends straight up from the base 110. In such embodiments, the first diameter D1 defined by the base 110 and a the second diameter D2 defined by the peripheral wall 120 are substantially equal. In yet another embodiment, the peripheral wall 120 may comprise only a straight portion 120B that extends from the base 110 in a manner such that the base 110 and peripheral wall 120 form an obtuse or acute angle.
In an embodiment, the drum body 105 is constructed, at least partially, of a metal material. In one such embodiment, the drum body 105 is constructed of a noncorrosive or corrosion-resistant material, such as stainless steel, chrome, aluminum, and the like to prevent rust or other deterioration of the drum body 105. In other embodiments, other materials such as wood, plastic, combinations thereof, or any other material suitable for the applications described herein may be utilized in the construction of the drum body 105. In some embodiments, the drum body 105 may be constructed so that the base 110, or at least a portion thereof, is flexible or semiflexible and acts as a diaphragm when the instrument 100 is played.
Each tonal element within the plurality of tonal elements 140 is configured to vibrate at a frequency within the range of audible frequencies for humans when struck or plucked. Each tonal element within the plurality of tonal elements 140 extends over a portion of a bottom surface of the drum body 105 and has a fixed first end 140A and a free second end 140B. As used herein, the “bottom surface of the drum body” may include the interior surface of the base 110A alone or, as shown best in
In one embodiment, the plurality of tonal elements 140 are formed within a single plate 130 such that each tonal element of the plurality of tonal elements 140 represents a portion of the plate 130 that was not cut and subsequently removed during manufacture. In an embodiment, the plate 130 is constructed, at least partially, of a metal material. To prevent rust or other deterioration of the plate 130, the plate 130 may, in some embodiments, be constructed of a noncorrosive or corrosion resistant material, such as stainless steel, chrome, aluminum, and the like. In other embodiments, other materials such as wood, plastic, combinations thereof, or any other material suitable for the applications described herein may be utilized for the plate 130. In some embodiments, the plurality of tonal elements 140 may be formed within the plate 130 via laser cutting or water jet cutting a metal plate. The diameter of the plate 130 is equal to or greater than the diameter of the rim 120C of the peripheral wall 120 so that the plate 130 can be disposed on top of and be secured to the rim 120C of the peripheral wall 120, as shown best in
In other embodiments, each tonal element of the plurality of tonal elements 140 may comprise an individual member that is separate from and unconnected to the other tonal elements. In such embodiments, the first end 140A of each tonal element may be secured to the peripheral wall 120 such that each tonal element is generally perpendicular to the peripheral wall 120 at the point of attachment and extends inwardly towards the center of the drum body 105. In one such embodiment, the first end 140A of each tonal element may be secured to the rim 120C of the peripheral wall 120.
As shown best in
When the instrument 100 is assembled, each tonal element of the plurality of tonal elements 140 is preferably secured proximate to the drum body's 105 open end 150. In some embodiments, the tonal elements may be arranged such that the plurality of tonal elements 140 are disposed along the same horizontal plane so that the plurality of tonal elements 140 are disposed at the same height above the bottom surface of the drum body 105. Alternatively, the tonal elements may be disposed at different heights about the plate 130 or secured at different heights about the peripheral wall 120. As shown by at least tonal elements 140F12 and 140F13 in
Each tonal element has a first side 140C and a second side 140D. As shown in
In some embodiments, the tonal elements within the plurality of tonal elements 140 may be divided into separate sets, where each set is secured at a different locations around the instrument 100. For instance, as shown in
As further shown in
In some embodiments, the instrument 100 may further comprise a protective guard 135. The protective guard 135 may act as a shock absorber to prevent the drum body 105 or plurality of tonal elements 140 from bending or otherwise deforming in instances where the instrument 100 is dropped or is otherwise subjected to strenuous forces. To this end, the protective guard 135 may be constructed, at least partially, of a rubber or plastic material. Alternatively, the protective guard 135 may be constructed, at least partially, of wood or any other suitable material. In some embodiments, the protective guard 135 may be designed to cover the entirety of the instrument's 100 exterior. In other embodiments, as shown in
Prior to playing the instrument 100, liquid 300, such as water, may be introduced into the interior of the drum body 105, as shown in
The drum body 105 may be filled within any volume of liquid 300, though the vibrational effect of the drum body 105, and specifically vibration of the base 110, on the liquid 300 may be most discernable when the volume of liquid 300 is such that the base 110 is partially covered or just barely completely covered. As the various tonal elements may vibrate at different frequencies, the vibrations experienced by the drum body 105, and thus patterns or designs within the liquid 300 contained therein, may also vary depending on which tonal elements are struck or plucked. Accordingly, striking or plucking the various tonal elements 140 may cause some of the liquid 300, as shown in
In addition to providing visual patterns or designs, introducing a liquid 300 into the drum body 105 may serve to provide an additional medium through which the sound waves emitted from the tonal elements may pass. When the instrument 100 is played without liquid 300, the sound waves emitted by the striking or plucking of the tonal elements pass through air alone, whereas the sound waves may pass through two mediums when liquid 300 is present in the drum body 105. Because the refractive index of air and a liquid 300, such as water, are generally different, the sound waves may be refracted such that that directional path and wavelength of the sound waves change as they pass from the air to liquid 300, thereby altering the pitch of the sound wave. Depending on the refractive index of the liquid 300 used, the extent to which the sound waves are refracted may vary. By rotating or tilting the drum body 105, users 400 may influence the location at which the liquid 300 pools within the drum body 105. Accordingly, by moving the drum body 105 users 400 may influence the extent to which sound waves emitted from struck or plucked tonal elements 140 pass through the liquid 300. In this way, users 400 may alter the pitch or otherwise affect the sound elicited from the tonal elements while actively playing the instrument 100.
