Description

[Detailed description of the invention] (Field of industrial application) This invention relates to the arrangement of keys in pianos, organs, accordions (including button type), xylophones, rebars, and other musical instruments.

(Prior Art) Conventional keys are arranged so that the first key row is arranged according to the scale of C major, and the adjacent pitches are whole steps in the scale of C major, so as to play sounds that are different by a semitone. The first key row is a white key on a piano, organ, etc., and the second key row is a black key.

(Problems to be Solved by the Invention) According to the conventional key arrangement described above, the second key row is provided to compensate for the sounds that are insufficient with only the first key row. For this reason, the second key row alone does not constitute a musical scale, and on pianos, etc., the black keys are narrower than the white keys.

In this way, the first key row is the main key row, and the second key row alone does not make up the scale, so the normal major key and the A major key (for example, C major and C major) A completely different fingering is now required when playing the . Also, when performing mainly on the second key row, it is unavoidable to use the first key row (white keys) because the second key row (black keys) does not constitute a complete scale. There have been cases where the fingering has become complicated.

(Means for solving the problem) The keyboard of this invention has a first key row 2 in which the keys are arranged according to the scale of C major, and a major key (B major or C major) that is a semitone different from this. ) and a second key row 4 in which the keys 3 are arranged according to the musical scale. The above-mentioned conventional problems are solved by arranging the keys of both key rows in a staggered manner so as to be shifted by about 1/2 the key width in the direction. In this invention, the term "key" includes not only the keys of a keyboard instrument such as a piano, but also the buttons of a button accordion, a xylophone, and the plates of a reinforcing bar.

In other words, in the conventional key arrangement, the first key row (white keys) simply follows the C major scale.
A second key row (black keys), which was provided only to compensate for the missing notes, was also added for sounds that were common to the first key row, and the second key row constituted a complete musical scale. It is designed to do so.

In this invention, the number of key columns is not limited as long as it is two or more. If there are three rows, a key row that is a semitone different from C major (if the second key row is B major, then C major) is provided in front of the first key row, or a second key row is used. A key row that is a semitone different from the second key row (if the second key row is B major, then B flat major) is provided behind the second key row.

In this way, since the second key row is provided according to the major scale, which is a semitone different from the first key row, all 12 notes included in one octave can be obtained by using two rows. Can be done.

(Function of the invention) In this invention, the second key row also independently constitutes a major scale, so the B major scale, which was previously difficult to play due to the high frequency of use of the black key, was created by using only the second key row. can play songs in C major using the same fingerings as C major. Also, a common sound is included in the first key string and the second key string. Therefore, by appropriately using keys with these matching sounds, the degree of freedom in fingering can be improved.

Hereinafter, embodiments of this invention will be described based on the drawings. Note that although the following embodiment will be described as an example applied to a piano, a similar key arrangement can be implemented for other musical instruments as well.

(Example 1) In Fig. 1, like the conventional white keys, C, D, E, F, G, A, B are played according to the scale of C major.
First, in the back of key row 2, keys 1 corresponding to each note of are arranged, B, C#, B, C#,
A second key row 4 is provided in which keys 3 corresponding to the sounds D#, E, F#, G#, and A# are arranged, and the key for the B sound in the second key row 4 is the key of the title. key row 2
It is located between the B note key and the C note key.

At the back of the second key row 4, there are notes of B♭, C, D, E♭, F, G, and A according to the scale of B flat major, which is a semitone different from the second key row. A third key row 6 is provided in which corresponding keys 5 are arranged, and the B♭ note key in the third key row 6 is connected to the B♭ note key and the B note key in the second key row 4. It is located between.

Furthermore, at the back of the third key row 6, there are A, B, C#, D, E, F#, A, according to the A major scale.
A fourth key row 8 is provided in which the key rows 7 corresponding to each note of ♭ (G#) are arranged.
The A note key is located between the A note key and the B♭ note key in the third key row 6, and the keys in each key row are arranged in a staggered manner.

In addition, circles 9 and other marks are placed on the top surface of the keys corresponding to key notes of the major scale in each key row, so that it is easy to determine what kind of scale each key row corresponds to. It is set as.

Each of the key rows has a step on the top surface of the keys constituting it, making it easier to press keys located at the back (FIG. 3). In each key row, keys corresponding to the same sound are attached to the same stick 10. For example, in FIG. 1, the C note of the first key row 2 and the third key row are both attached to the same striking rod 10, and the C note of the second key row and the fourth key row
Both #sounds are attached to the same striking rod 10a.

In order to arrange the keys in this way, the shape of each key is such that the attachment part to the striking stick 11 is narrow, as shown in Figure 2, so that the striking stick can accommodate all notes within the width of one octave. 10 can be installed with equal width.

Here, the widths of keys 1, 3, 5, and 7 of each key row are the same, and regardless of which key row it is, the keys whose sounds correspond to the sounds of conventional white keys are white. Keys with tones corresponding to conventional black keys are colored black.

According to this embodiment, since the width of the keys in each keyboard row is the same, it is possible to eliminate keystroke errors caused by the narrow width of the keys in conventional black keys.

Also, when playing the C major scale, it is possible to use only the first key row 2, as when using a conventional keyboard, but the chain line a or b
As shown in , it is also possible to use the first to fourth key rows as appropriate to select a fingering that is appropriate for the situation. In addition, the scales of B major, B flat major, and A major other than C major can be played using only one row of keys in the same way as the conventional C major, and the scales of other major keys can also be played using the same key row as the conventional C major. As with the major key, the right hand can play with the following fingerings starting from the C note: thumb, index finger, middle finger, thumb, index finger, middle finger, ring finger, and little finger.

(Embodiment 2) Next, in the embodiment shown in FIG. 4, the width of the keys is changed in order to make it easier to recognize whether the pitch difference between adjacent keys is a whole tone or a semitone.

In other words, if we take the first key row that follows the C major scale as an example, there are keys between E and F, and between B and C.
Since the pitch difference between the notes is a semitone, the right side of the key 11 of the E note and the left side of the key 12 of the F note are cut, and the right side of the key 13 of the B note and the left side of the key 14 of the C note are cut. However, the width of each key is narrowed, and the distance between adjacent keys is made close to each other, so that it is visually clear that the pitch difference between these keys is a semitone.

According to this embodiment, the interval between each key can be visually recognized, so if one understands the rules of scales, one can immediately play the correct scale in any key.

(Reference example) Furthermore, Fig. 6 shows a first key row 15 in which white keys and black keys are arranged horizontally in a row on a conventional piano keyboard.
There is a second key row 16 in which only the conventional black keys are arranged, and further behind it there are various chord constituent tones. Key rows 17, 18, 19, 20, 21, and 22 are provided in which keys corresponding to those shown are arranged. According to this arrangement, an arpeggio can be easily played by using key rows corresponding to various chords. The key rows corresponding to these various chords can be implemented in combination with the key arrangement of this invention or any other key arrangement. Note that the key rows of keys corresponding to the above-mentioned chords can be provided as appropriate to correspond to the desired chords.

Note that the number of key strings may be two or more, and in some cases, it is possible to provide key strings corresponding to all major keys.

(Effects of the invention) According to this invention, the first key row that follows the major scale and the second key row that is composed of the notes of the major scale, which are different from this, are arranged one after the other. Unlike the black keys, only the second key row constitutes one scale. Therefore, by using the second key row, scales other than C major can be played with the same fingering as C major, and the number of fingering patterns can be reduced.

In addition, there are common sounds in the first key row and the second key row, and the keys that correspond to the same sound are shifted to the left and right by about 1/2 the key width, so
By using these, you can select and use the keys of the first key row or second key row as appropriate depending on the arrangement of notes, improving the degree of freedom in fingering and making playing easier. .

Furthermore, by using the first key row as conventional white keys and using them together with the sounds corresponding to conventional black keys in the second key row, it is possible to perform with the same fingering as on a conventional keyboard.
