Definitions
- the present invention relates generally to keyboard type musical instruments and more particularly relates to keyboard configurations directed to and offering unified fingering and as a result ergonomic optimization with regard to the human hand.
- the prior art broadly includes the standard piano keyboard configuration developed centuries ago which has become accepted as a practical compromise to the complex problem of interfacing the human hand to a music making device.
- a key disadvantage is the narrow separation currently existing between the black keys for playing the white keys which may pose serious problems for those musicians having large fingers. It is further noted that because of the major differences between black and white keys be it in size, shape, elevation, positioning or distance, it follows that the human hand must be contorted to access different keys thereby making piano playing technique complex.
- each hand digit will relate differently to each one of these areas. For instance, using the thumb or small finger for playing/accessing black keys might require a twisting of the wrist. Since different areas present different playing axis, the fingers must be trained to compensate for different touch due to differences in distance from the key pivot, leverage, relative key mass location, dynamics etc. All of this requires a great deal of arm, hand and finger movement leading to fatigue and pain.
- U.S. Patent Nos. 5,440,071 ; 4,926,734 ; 3,342,094 and 4,031,800 Some prior art known to the applicant is found in U.S. Patent Nos. 5,440,071 ; 4,926,734 ; 3,342,094 and 4,031,800 .
- U.S. Patent No. 5,440,071 would appear to propose the closest device to the applicant's proposed structure disclosed hereinafter in that it offers keys of similar size and shape to the traditional piano-style key, yet there are no black keys in between the white keys.
- the present invention overcomes the above referred to difficulties and problems in a convenient, simple and efficient manner.
- Another object of the present invention is to provide a unified fingering system.
- Yet another object of the present invention is to provide a musical instrument keyboard comprising a plurality of black and white keys, and key responsive means for enabling the generation of tones associated to said keys, respectively, said keys being identically shaped and sized and arranged on a single plane in a parallel and fully adjacent manner relative to one another.
- Figure 1 is a plan view of the keys of a keyboard in accordance with the present invention.
- the finger 'set' in each hand does not change with the circumstances, as described above for the regular keyboard, since all the keys are on the same level.
- the keyboard of the present invention can be played with much less complication and in a more comfortable fashion than a regular keyboard.
- the keyboard retains all the traditional features used on standard keyboards except for the fact that its keys are all of the same size and have the same shape.
- Keyboards produce sounds by activating vibrations in various ways: Striking tensioned steel strings in pianos, blowing air through reeds in accordions and electronically controlled membranes in electronic keyboards.
- the first sequence of key notes considered is the fixed musical scale on the keyboard.
- the second sequence of notes considered is a notional moveable 'solfege' scale used in composing, writing and playing music.
- Do' N is a chromatic scale number.
- the ratio of the sound frequency for any note (N) to that of the tonic (0, Do) is: 2 (N/12)
- the major scale notes are: (0, Do) (2, Ra) (4, Me) (5, Fa) (7, So) (9, La) (11, Ti) (12, Do')
- the minor scale notes are: (0, Do) (2, Ra) (3, Re) (5, Fa) (6, Fi) (9, La) (11, Ti) (12, Do')
- the major chord is: (0, Do) (4, Me) (7, So) (12, Do')
- the minor chord is: (0, Do) (3, Re) (6, Fi) (12, Do')
- Other chords can be defined in a similar way.
- Keyboard key notes for the scales and the keyboard notes for any chord in any key can be determined by superposing the 'solfege' scale over the fixed keyboard scale.

Description
- Not applicable.
- Not applicable.
- Not applicable.
- The present invention relates generally to keyboard type musical instruments and more particularly relates to keyboard configurations directed to and offering unified fingering and as a result ergonomic optimization with regard to the human hand.
- The prior art broadly includes the standard piano keyboard configuration developed centuries ago which has become accepted as a practical compromise to the complex problem of interfacing the human hand to a music making device.
- The musician faces some disadvantages but the main advantages of relative simplicity, universal acceptance, standardization and mass-producibility have made it to date the de facto standard.
- A key disadvantage is the narrow separation currently existing between the black keys for playing the white keys which may pose serious problems for those musicians having large fingers. It is further noted that because of the major differences between black and white keys be it in size, shape, elevation, positioning or distance, it follows that the human hand must be contorted to access different keys thereby making piano playing technique complex.
- There exists three main key playing areas being the full width portion of the white keys, the narrow portion of the white keys between the black keys, and finally the black keys themselves. As a result, each hand digit will relate differently to each one of these areas. For instance, using the thumb or small finger for playing/accessing black keys might require a twisting of the wrist. Since different areas present different playing axis, the fingers must be trained to compensate for different touch due to differences in distance from the key pivot, leverage, relative key mass location, dynamics etc. All of this requires a great deal of arm, hand and finger movement leading to fatigue and pain.
- Some prior art known to the applicant is found in
U.S. Patent Nos. 5,440,071 ;4,926,734 ;3,342,094 and4,031,800 .U.S. Patent No. 5,440,071 would appear to propose the closest device to the applicant's proposed structure disclosed hereinafter in that it offers keys of similar size and shape to the traditional piano-style key, yet there are no black keys in between the white keys. - The present invention overcomes the above referred to difficulties and problems in a convenient, simple and efficient manner.
- Accordingly, it is a primary object of the present invention to provide an ergonomically adapted keyboard overcoming the above mentioned disadvantages of the prior art.
- Another object of the present invention is to provide a unified fingering system.
- Yet another object of the present invention is to provide a musical instrument keyboard comprising a plurality of black and white keys, and key responsive means for enabling the generation of tones associated to said keys, respectively, said keys being identically shaped and sized and arranged on a single plane in a parallel and fully adjacent manner relative to one another. Other objects and advantages will be described hereinafter.
-
Figure 1 is a plan view of the keys of a keyboard in accordance with the present invention. - By way of technical background, when playing the notes of musical scales (major, minor) on a keyboard, the mix of black and white keys, for each scale, depends on the key in which the music is played. Similarly when playing various chords (major, minor, augmented, diminished etc.), the mix of black and white notes, for any one type of chord, varies with the keyboard tonic note for the chord.
- As earlier discussed, having to change the mix of black and white keyboard notes for the same basic pattern of uniquely defined solfege notes and chords involves using complicated different fingering for the two tiered black and white levels of regular keyboards.
- For the keyboard of the present invention the finger 'set' in each hand does not change with the circumstances, as described above for the regular keyboard, since all the keys are on the same level.
- As a result, the keyboard of the present invention can be played with much less complication and in a more comfortable fashion than a regular keyboard.
- Two examples are given of the mix changes between black and white notes for the same musical chord:
- 1) KEY of C and / or Tonic C for chords.
- It is also noted that standard keyboard players would immediately be able to play the keyboard of the present invention with no change required in their playing techniques.
- The keyboard retains all the traditional features used on standard keyboards except for the fact that its keys are all of the same size and have the same shape.
- Keyboards produce sounds by activating vibrations in various ways: Striking tensioned steel strings in pianos, blowing air through reeds in accordions and electronically controlled membranes in electronic keyboards.
- To assist in describing the advantages of the keyboard of the present invention, the musical theory subjects of scales, chords and the Keys for playing music are examined.
- For this the concept of two sequences of notes are used. These sequences are in the form of chromatic scales where the sound frequencies associated with the notes are such that the ratio of the frequency of sound of each note to that of the preceding note is: 2 (1/12)
- The first sequence of key notes considered is the fixed musical scale on the keyboard.
- The second sequence of notes considered is a notional moveable 'solfege' scale used in composing, writing and playing music.
- Music in Western Countries is mostly centered on major scales. The major scale notes on the keyboard associated with any playing key and the notes for any type of chord can be determined by superposing the 'solfege' scale over the keyboard scale.
- This is a chromatic scale. The black notes used on standard keyboards are retained as this enables instant recognition of the keys. The keys are also tuned to the standard frequencies. In a detailed design of an H keyboard there is no requirement for the key surfaces to be flat. The surfaces could be, for example, triangular or semi circular cross sectioned cylinders along their lengths. The number of 'octaves' covered can be typically four for small keyboards up to seven plus for pianos or larger keyboards.

The ratio of the sound frequency for any note (N) to that of the tonic (0, Do) is: 2

The major scale notes are:
(0, Do) (2, Ra) (4, Me) (5, Fa) (7, So) (9, La) (11, Ti) (12, Do')
The minor scale notes are:
(0, Do) (2, Ra) (3, Re) (5, Fa) (6, Fi) (9, La) (11, Ti) (12, Do')
The major chord is: (0, Do) (4, Me) (7, So) (12, Do')
The minor chord is: (0, Do) (3, Re) (6, Fi) (12, Do')
Other chords can be defined in a similar way. - Keyboard key notes for the scales and the keyboard notes for any chord in any key can be determined by superposing the 'solfege' scale over the fixed keyboard scale.

Figure 1 shows a plan view of a musical instrument keyboard 10 having identically shaped andsized keys 11 arranged on asingle plane 12. It is further noted that every key has the exact same shape and is of equal size making it easier as a result to access and play all keys/notes whether they are black 13 orwh ite 14. - It is also apparent that it would be possible to extend the keyboard 10 to the right and/or to the left by adding any number of rows in order to obtain the desired overall range of musical notes.
- As a human hand and fingers are positioned over the keyboard 10 both the black 13 and white 14 keys are equally accessible for play in more natural manner and for a greater number of musicians. There is no requirement for musicians to change their playing style as there would only be a minimal period of adjustment to get accustomed to the new keyboard.
- In operation, a musical instrument, such as a piano for instance, is comprised of a keyboard 10 having a plurality of
keys 11 connected to responsive means for enabling the generation of tones associated to saidkeys 11, respectively, thekeys 11 being arranged in a parallel and fully adjacent manner relative to one another on asingle plane 12. The tone generated by thekeys 11 are substantially within the tonal range of a standard piano. - Other embodiments and uses of the invention will be apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed herein. The specification and examples should be considered exemplary only and do not limit the intended scope of the invention.
