Description
sackground of the Invention Field of the Invention My invention relates to geometric form and tone pattern aspects of a keyboard for a musical instrument, and to a new musical instrument employing my keyboard.
Description of_the Prior Art Conventional keyboards for instruments such as pianos, accordians, organs, and the like include a linear series or row of white and black keys representing a progression of tones arranged left to right in an ascending order. The white keys correspond to the natural diatonic scale. The black keys represent the accidentals or sharps and flats.
Several disadvantages of the conventional keyboard are discussed in U.S. Patent No. 3,342,094, granted September 19, 1967, to ~rvin r-i. Wilson. This patent presents a keyboard which is composed of a plurality of vertically extending rows of vertically elongated push-button type keys. As discussed in the patent, the keyboard disclosed by the patent was designed to overcome several of the disadvantages of the conven-tional keyboard.
The patentee states that he has provided a keyboard in which: (1) _~ .
the pitch span of a single hand is vastly increased, so that octaves, tenths and the like are easily played by a musician even with physically small hands; (2) the position of the various keys of the keyboard is such that they will fall under the more natural physiological positions of a player's fingers when his fingers ~k : :~
and hands are in a relaxed position; and (3) the placement and fingering on the keys is identical when transposing a tune from one tonic to a different tonic.
It is an object of my invention to overcome these same disadvantages of a conventional keyboard. My keyboard is also better adapted to the human hand and fingers and the place-ment of the fingers on the keys is identical when transposing a tune from one key to a different key. However, it is with these common objectives that any close similarity between my keyboard and the keyboard disclosed by U.S. Patent No. 3,342,094 stops.
My keyboard is particularly well adapted for use with tone generating equipment of the type found in "synthesizers".
However, the tone generating apparatus is not a part of my invention. For this reason, and also because the technology involved is both well developed and readily available I have omitted disclosing any particular type of tone generating equip-ment. Examples of readily available publications which disclose tone generators in considerable depth are: Electronic Musi-cal Instruments, Third Edition, by Richard A. Dorf, Mahony & Roese, Inc., 67 - 31316 (1968); and The Electrical Reproduction of Music, by Alan Douglas, Philosophical Library, J. Y. (1957).
~ The following additional patents, relating to keyboards for musical instruments (and some also disclosing tone generating equipment), should be consulted for the purpose of properly evaluating the subject invention and putting it into proper perspective: No. 2,250,522, granted July 29, 1941, to Saturnino T.
10745~7 Bonilla; ~lo. 3,012,460, granted December 12, 1961 to Ervin M.
Wilson; No. 3,067,645, granted December 11, 1962, to Mario Moschino; .~o. 3,417,648, granted December 24, 1968 to Arnold Honig and No. 3,468,209, granted September 23, 1969 to Clodovo G. G. Barreto.
Summary of the Invention My keyboard is basically characterized by a two-dimen-sional pattern of at least six horizontal rows of keys and at least six perpendicular vertical rows of keys. The tones repre-sented by the keys are arranged horizontally from left to rightin ascending half-steps or microtones and are stacked vertically in ascending perfect fourths. The center-to-center spacing of the keys, both horizontally and vertically, is no greater than about one inch.
~1~y keyboard is more technically and musically facile than the standard piano keyboard. Wide intervals involve no stretching or awkward positioning of the hands. It has an expandible range, while offering compactness and symmetry. Its use makes music more readable, accessible and transposable. In preferred form, my ]ceyboard is constructed to have a range of seven and one-half octaves and the tones are divided horizontally in half-steps. This range can be varied by r.~erely adding or ~ ~ r substracting vertical and/or horizontal rows of keys. The key-board remains relatively compact even if expanded beyond the range of the human ear.
My keyboard presents a symmetrical grid pattern of advantageously sized and spaced keys. It facilitates uniform 1079~597 scale and chord patterns, transposition and improvisation. The scales and chords involve the same pattern from key to key.
Transposition involves merely a symmetric shift of pattern, with identical fingering. The symmetrical grid pattern, by its nature, results in note duplication, making possible the playing of unisons and employment of alternate fingering.
My keyboard permits use of a ten finger technique in which either hand may function in any register. One hand can span from about three to about seven and one-half octaves, depending on the selected size of the key areas. Thus, two and three part counterpoint and four and five part harmony are one hand possibilities.
All standard piano and organ literature is playble on my keyboard. My keyboard, because of its grid pattern, permits the use of tablature, as employed in medieval guitar and lute literature. The grid pattern of my keyboard also permits the study of music as geometric patterns and makes possible the composition of music from geometric patterns, i.e. two dimensional diagrams.
Another important object of my invention is to provide a keyboard which has a direct relationship to a guitar or other strin~ed and fretted instrument that is tuned to correspond to similarly adjacent horizontal rows of keys on the keyboard. The common note arrangement facilitates both cross-learning and a -free exchange of musical ideas.
These and other features, objects and advantages of my keyboard, and of an electronic tone generator type musical instrument, or the like, utilizing such keyboard, will be apparent from the following detailed description of certain preferred embodiments of the invention.
Brief Description of the Drawing FIG. 1 is a fragmentary plan view of the keyboard portion of a musical instrument incorporating my invention, such view showing both a geometric arrangement of the keys into perpenclicular horizontal and vertical rows, and the tone pattern of the keys, such view including the written range of the entire keyboard, the range of a portion of the keyboard corres-ponding to the fingerboard of a guitar tuned in fourths, and that section which approximates the required range of academic four-part writing;
FIG. 2 is a view like FIG. l, but including tone notations on only keys corresponding to two different key patterns of a single major scale, G sharp major;

107459~
FIG. 8 is another fragmentary view of the keyboard showing the keys which are identified in FIGS. 5 - 7 super-imposed in a single view;
FIG. 9 is a view like FI&. 1, but with tone iZentifi-cation for only those keys corresponding to the note C and theother keys situated in the first vertical row and the bottom horizontal row, such view illustrating the symmetry of the keys corresponding to any given note;
FIG. 10 illustrates three different ways of writing the same two measures of music for use in playing a musical instrument embodying my keyboard; ana FIG. 11 is a view like FIG. 1, but of a keyboard with the tones represented by the lceys being arranged horizontally from left to right in quarter steps, and stacked vertically in perfect fourths.
Description of the Preferred Embodiments As shown by FIG. 1, a keyboard 10 constructed in accordance with the present invention may occupy a corner portion of a musical instrument 12. Instrument 12 also includes apparatus for producing musical tones when the keys 14 (only some of which are referenced in the drawing) are touched and a suitable amplification system, neither one of which forms a part _, .
of the present invention.
The housing of instrument 12 may comprise a flat upper panel 16 having a plurality of holes formed therein through which the keys 14 project. Panel 16 may be horizontal or may slope downwardly towards the user.
The keyboard 10 is basically characterized by a plurality of horizontal and vertical rows of keys which are exactly perpendicular to each other. ~ach key 14 is centered within a square or rectangular area that measures no greater than about one inch along each side. Thus, the center-to-center spacing of the keys 14, both horizontally and vertically,is no greater than about one inch. In the illustrated e~bodi-ment the keys 14 are square and are constructed in a manner quite similar to the way that the push buttons of a push button type dial phone (i.e. a touch tone phone) are constructed. Of course, in other embodiments, the keys 14 may have a different shape, e.g. round. Keys 14 may be adapted to produce tones electronically by touch, light, heat sensitivity, etc. As previously explained, this aspect of the instrument 12 is not a part of the invention.
According to my invention, the tones represented by the keys 14 are arranged horizontally from left to right in either ascending half-steps or microtones. In preferred form the tones are arranged horizontally in half-steps, the smallest interval in ~Jestern music. Also according to my invention, the tones represented by the keys 14 are stacked vertically in ascending perfect fourths, the strongest interval in ~estern music.
The illustrated embodiment comprises sixteen horizontal rows of keys and sixteen vertical rows of keys. A subcontra G
_sharp tone is selected for the lower left corner key 14. This results in the upper right corner key representing a five-line d tone. In FIG. 1, the particular tone represented by each key 14 o~ the keyboard 10 is delineated on the key 14. FIG. 1 includes a grand staff positioned above the keyboard 10 which shows the full written range of the keyboard 10. This range extends from a half-step below the range of a standard eighty-eight key piano ]ceyboa:rd to a whole step above such piano keyboard. ~he logic of the grid arrangement of my keyboard is illustrated in the lower central portion of FIG. 1 by a chromatic scale 18 ~commencing with the fifth horizontal key in the lowermost vertical row), which is compact, easy to see, and easily fingered with one hand.
The grid form of my keyboard makes both melody and harmony symmetric and geometric. Each note falls uniformly on vertical, horizontal and diagonal lines. This note pattern is shown by FIG. 3 in which the note C has been selected by way of example. Thus, melody and harmony form patterns on the keyboard and these patterns retain their quality (viz. major, minor, dim- ;
inished --- ) no matter where placed. Transposition involves only a simple e~uiparallel pattern shift, as is shown by FIGS. 3 and 4. Comparing FIG. 3 with FIG. 1, the note C at the lower end of the scale is designated 20 in each of these figures. The note d~ at the lower end of the D sharp major scale shown by FIG. 4 is designated 22 in both FIG. 4 and FIG. 1. FIGS. 3 and 4 clearly illustrate identical scale patterns, differing only with respect to their position on the keyboard.
Improvisation is aided by the fact that chord and scale patterns do not vary. By way of example, reference is made to FIGS. 5 - 8 which relate to the chord and scale patterns of basic blues music. FIGS. 5 - 7 illustrate that the primary ~chords and scale patterns of any key are vertically adjacent patterns. ~IG. 8 shows the keys which are identified in FIGS. 5 -7 together in a single view. ~his feature of constant chord and scale patterns makes possible the study of music as geometric patterns and the composition of music from geometric patterns, i.e., two dimensional diagrams.
1~:)74597 ~ 11 standard piano and organ literature is readable and playable on my keyboard. Because of its grid pattern, my keyboard also permits the use of tablature, as employed in medieval auitar and lute literature. By way of example, FIG. 8 shows two measures of Bach Chorale No. 233, in standard staff and note form, and also two different ways of tablating the same ~us ic .
A ten-finger technlque may be employecl for playing my keyboard, with either hand functioning in any register. One hand can span from about three to about seven and one-half octaves or any five note harmonic figuration in between, depending on the size of the key areas. Two and three part counterpoint as well as four and five part harmony is playable with one hand. This makes it possible to play most beginning and intermediate piano literature single handed.
One very important advantage of my keyboard is that there is a note duplication which allows for unisons and alternate fingering. Unisons make possible opposing colorings, as found in organ literature or voice and instrument arranging. ~y way of example, FIG. 2 illustrates two different patterns for the - same scale, made possible by the note duplication. This allows for total right ancl left hand freedom.
Referring back to FIG. 1, a portion of the keyboard that corresponds to the strings of a guitar (or other stringed _and fretted instrument having at least six strings) tuned in perfect fourths is designated 24. Thus, a musical instrument employing my keyboard, and including keys representing at least tnose tones included in the rectangular space 2~, would share all scale and chord patterns with a stringed instrument which is tunecl in fourtlls. This identity would make it easier for 107459~
tne student of one of these instruments to learn how to play the other. Also, music written for an instrument employing my key-board can be played on a stringed and fretted instrument tuned in fourths, and vice versa. The electric fretted bass, being tuned 5 in fourths, already corresponds to my keyboard. The mandolin is a logical additional instrument that could be tuned in fourths so that it would have a direct correspondence to an instrument employing my keyboard.
Referring again to FIG. 1, the portion oi keyboard 10 10 contained within the area 26 encompasses the range requirements Y
of soprano, alto, tenor and bass (SATB) writing. An electronic tone generator type musical instrument involving an eight key by eight key keyboard, corresponding to the tones represented within area 26 of FIG. 1, would meet the technical and musical 15 demands of academic theory and at the same tirne would offer compactness and portability. A musical instrument of this charac-ter would enable a student to utilize existing piano pedagogy and its size would make it ideal for classroom teaching and use where conventional piano practice facilities are limited.
The range of my keyboard can be extended or contracted without creating any technical problems, merely by adding or subtracting horizontal and/or vertical rows of keys to or from the grid.
As stated above, a keyboard measuring sixteen keys by ~ixteen keys approximates the range of the piano, whereas a board measuring thirty-two keys by thirty-two keys would exceed the range of the human ear, but at the same time would be quite small and compact.
According to an aspect of the present invention, the pitch difference between horizontal keys can be subdivided so that the tones are arranged horizontally in evenly spaced microtones. A quarter tone scale could easily be produced by adding a note between each horizontal note in the keyboard of FIG. 1. A portion of such a keyboard, and the smooth ten-finger quarter tone pattern that would be involved, is shown by FIG. 11.

A quarter tone scale could easily be produced by adding a note between each horizontal note in the keyboard of FIG. 1. A portion of such a keyboard, and the smooth ten-finger quarter tone pattern that would be involved, is shown by FIG. 11.
