2. Description of the Related Art Conventionally, a musical instrument keyboard is composed of a white key and a black key, but each key is unified in black or white, and there is no indication about the load. Since the fulcrum of the key of the musical instrument keyboard is inside the musical instrument, it is necessary to depress the key with a smaller load toward the outside of the keyboard, and to depress the key with a greater load toward the inside of the keyboard. Since the white key and the black key are provided at different heights and positions, it is difficult to balance the pressing load. Skilled players study the fingering method between white and black keys when playing a song and determine the fingering that the player is most satisfied with. It is very difficult for beginners to play the white and black keys in a well-balanced manner, and they will learn through repeated practice. The balance between the white key and the black key is also important for tone adjustment for adjusting the tone and volume.

[0003]

However, in the conventional keyboard for musical instruments, there is no indication about the load of the white key and the black key. For this reason, there is a problem that it is difficult to play with a balance between the white key and the black key. In other words, even a skilled player decides how to use the white key and the black key, and which part of the key should the finger hold even for beginners to play the white key and the black key in a balanced manner? think of. However, in the conventional keyboard for musical instruments, there is no mark indicating a position where the load required to press down the white key and the black key is equal, so that the experience and feeling have to be relied on.

[0004] Also, when performing sound adjustment, the balance between the white key and the black key is very important. However, with a conventional keyboard for musical instruments,
Even if the key is pressed down with the same load, it is not easy to accurately correspond the position between the white key and the black key. For this reason, there is also a problem that the white key and the black key cannot be tuned in a well-balanced manner unless a person skilled in sound adjustment is used.

The present invention has been made to solve such a problem, and makes it possible to easily play a white key and a black key in a well-balanced manner, and furthermore, to balance sound with the white key and the black key. It is an object of the present invention to provide a musical instrument keyboard capable of easily performing a musical key.

[0006]

The present invention employs the following configuration in order to achieve the above object. That is, the gist of the invention is a keyboard for a musical instrument, characterized in that white and black keys at which the load required to depress them are substantially equal are marked at corresponding positions on the upper surface and / or the side surface.

[0007]

According to the musical instrument keyboard of the present invention, the positions of the upper surface and / or the side surface of the white key and the black key at which the load required for depressing are substantially equal are marked. Therefore, the player can easily know which part of the white key and the black key should be pressed to depress the key with the same load. In addition, when the keys are depressed with the same load during tone adjustment, it is easy to correspond the position between the white key and the black key.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is an explanatory diagram showing a keyboard 1 as one embodiment of the present invention. The keyboard 1 is a well-known keyboard for musical instruments, such as a piano, and includes a white key 3, a black key 5, and the like.

As shown in FIG. 1 (a), marks 31a to 31c and 51a to 51c are provided at corresponding positions on the upper surfaces of the white key 3 and the black key 5, respectively, at which the load required for pressing down is substantially equal.
Is provided. For example, in a grand piano, at the position of the white key upper surface first mark 31a provided on the white key 3, the load required to depress each white key 3 is typically about 50 g. A small circle is used as the mark on the first mark 31a of the white key upper surface. Similarly, at the position of the second mark 31b on the white key upper surface, about 6
A load of about 90 g is required to depress the white key 3 at 0 g and the white key upper surface third mark 31c. The white key upper surface second mark 31b is triangular, and the white key upper surface third mark 31c is x.

[0010] Correspondingly, marks 51a to 51c are provided at corresponding positions on the upper surface of the black key 5, respectively. For example, in a grand piano, a load of about 50 g is typically applied at the position of the first mark 51a of the black key upper surface, about 60 g at the position of the second mark 51b of the black key upper surface, and about 90 g at the position of the third mark 51c of the black key upper surface. Is required to depress the black key 5.
The mark provided on the black key 5 also corresponds to the white key 3, and the black key upper surface first mark 51a has a small circle, the black key upper surface second mark 51b has a triangle,
In the third mark 51c of the upper surface of the black key, x is provided as a mark. Since the fulcrum of the keyboard 1 is inside the musical instrument, the key can be pressed down with a smaller load toward the outside of the keyboard 1, and the key needs to be pressed down with a larger load toward the inside of the keyboard 1.

The keyboard 1 also has marks 33a-33 on the sides of the white key 3 and the black key 5, respectively, as shown in FIG.
c, 53a to 53c are provided. The white key side surface first mark 33a is provided on the side surface corresponding to the white key upper surface first mark 31a. For example, in a grand piano, as a standard, the white key 3 is pressed down at the position of the white key side first mark 33a. The required load is about 50 g. Also the white key side 1
The mark 33a is also a small circle like the white key upper surface first mark 31a. Similarly, the white key side face second mark 33b corresponds to the white key upper face second mark 31b, and the white key side face third mark 33c is the white key upper face third mark.
Each corresponds to the mark 31c.

Marks 53a to 53 provided on the side surface of the black key 5
c is the same as in the case of the white key 3 and the black key side first
The mark 53a corresponds to the black mark upper surface first mark 51a, the black key side surface second mark 53b corresponds to the black key upper surface second mark 51b, and the black key side surface third mark 53c corresponds to the black key upper surface third mark 51c. doing.

FIG. 2 is a graph showing the relationship between the displacement of pressing down the white key 3 and the load required for the displacement.
As shown in FIG. 1B, the displacement d to push down indicates a displacement to push down the white key 3. FIG. 2A shows a load required when the white key 3 of the grand piano is pressed down at the position of the first mark 31a on the white key upper surface. This is the same as the load displacement required to depress the black key upper surface first mark 51a of the black key 5. As shown in the drawing, first, about 50 g is required to push down from the displacement a1 to the displacement a2. In the keyboard 1 shown in FIG. 1, the load required to press down is the load required between the displacements a1 and a2. When the displacement reaches a2, a large load is applied. This is because when the white key 3 is pushed down to the displacement a2, the tip portion provided at the back of the fulcrum hits the damper lever, so that a larger load is applied. When the pushdown is further advanced and reaches the displacement a3, Jack starts to push up the sailor. A larger load is required from here to the displacement a4. Displacement a
When it reaches 4, the hammer strikes the string and reaches the displacement a5.
At the same time, the load suddenly decreases, and the load increases again as it approaches the limit of pressing down the white key 3.

FIG. 2B shows the load required when the same white key 3 is pressed down at the position of the third mark 31c on the white key upper surface. This is the same load displacement as pushing down the black key 5 at the position of the third mark 51c on the black key upper surface. The displacements a1 to a5 in FIG. 2A correspond to the displacements b1 to b5, respectively. As is clear from the figure, the white key upper surface third mark 31
At the position c, the displacement is small, but the first mark 31
The load required to push down is larger than the position a. For example, the load required to push down to the displacement b1 to the displacement b2 is about 90 g. Even thereafter, a large load is required as a whole. As described above, even with the same white key 3 or black key 5, the load greatly differs depending on the pressed position.

When performing using the keyboard 1, the player can play the black key upper surface first mark 51a of the black key 5 with the load used for the white key upper surface first mark 31a of the white key 3, for example. It is easy to know that sounds of the same intensity can be obtained. Also, from the white key upper surface second mark 31b of the white key 3 to the black key upper surface third
When playing the mark 51c or the like, it is necessary to consider how much force should be applied to play with the same strength.
1a to 31c and 51a to 51c are very helpful. In particular, it is very difficult for a beginner to balance the white key 3 and the black key 5, but such marks 31a to 31c, 51
By providing a to 51c, it is possible to efficiently learn even when practicing fingering.

Further, even in the case of sound adjustment, since the position at which the load required to press down on the upper surface of the white key 3 and the black key 5 becomes almost equal can be known, the white key 3 and the black key 5 are adjusted while being balanced. Makes sound very easy. For this reason, the efficiency of the sound conditioning work is increased, and more pianos can be sounded in a short time.

As described above, in the keyboard 1 of the present embodiment, the marks 31a to 31d are formed on the upper surfaces of the white key 3 and the black key 5 at which the load required for depressing the white key 3 and the black key 5 is substantially equal.
31c, 51a to 51c are provided. Therefore, the player can easily know which part of the white key 3 and the black key 5 the finger can be pressed down with the same load. Also, when the keys are depressed with the same load during tone adjustment, it is easy to correspond the positions between the white key 3 and the black key 5.

In this embodiment, the marks 33a to 33c and 53a to 53c are also provided on the side surfaces of the white key 3 and the black key 5, respectively. In particular, when the player does not like to provide the marks on the upper surface. It is conceivable to provide it on the side surface in this way. In general, the larger the size of a piano, the longer and more expensive the keyboard, but an electronic musical instrument such as an electronic piano cannot have a longer keyboard due to its structure. Therefore, even if the portions of the keyboard that can be touched have the same length, the amount of change in the load required by the position of the finger is greater in an electronic piano or the like than in a grand piano or the like. Particularly in the case of an electronic piano or the like having a large load change amount on the keyboard, the marks 31a to 31c, 51
The effect of providing a to 51c becomes remarkable.

In the keyboard 1 of this embodiment, marks 31a to 31
Although marks such as small circles, triangles, and crosses are used as c, 51a to 51c, they may be made inconspicuous as color marks or their positions may be indicated as lines so as not to impair the appearance. Characters such as numbers may be arranged as the marks.

Further, these marks may be adhered to a sticker or the like, or may be erased by wiping them off. By being able to remove the seal, it is possible to practice with reference to the seal only during the period when a novice or the like learns fingering. The mark can be removed when the learning has progressed to some extent and it is no longer necessary.
