Description

The present invention relates to playing musical instruments.

  1. Playing a violin string with a bow is called bowling. When playing a song with a violin, a beautiful tone can be produced by bowing the F-shaped hole formed on the violin at right angles to the string. However, since the bow is held by the performer and bowed, it moves in a free state and cannot maintain a right angle or deviates from the top of the F-shaped hole.

2. In order to increase or decrease the strength according to the instructions of the score, it is required to adjust the pressure of the left hand bow against the strings.

3. Besides the one problem, the gripped bow may bend up and down regardless of the player's intention, and the bow may hit a string that is not about to be played.

Until now, there was something that could be attached directly to the violin as a bowing practice tool. For example, in Japanese Patent Application Laid-Open No. 2002-268627, the bow can be guided at right angles to the strings, so that there was a temporary practice effect. However, since the training device is directly attached to the violin and configured to practice with the violin, when practicing bowing, it bows at various angles or is heavier than the bow (for example, a metal rod). ) Couldn't practice Boeing. In addition, since the bow is not surrounded, even if it can cope with the lateral pressure, it was not possible to practice with increasing the pressure. Also, when practicing bowing with a violin and a bow, the rotation around the axis of the bow is stopped and the right finger can not be applied to improve the flexibility, so effective bowing practice is performed. There was a difficult problem.
JP 2002-268627 A

  In the present invention, when the performer bows, the trajectory of the bow is always experienced so as to pass through a predetermined position, the muscles are strengthened, the performer's bowing is corrected, the right wrist The aim is to provide a bowing practice tool for musical instruments that aims for flexibility of fingers and the right hand.

A bowing practice tool for a musical instrument of the present invention comprises a main body imitating a violin, a rotatable rotating body mounted on the main body, and a bow guiding body on the rotating body, and the bow guiding body guides the bow. Practice.
Also, a main body imitating a violin, a rotating body placed on the main body, and a bow guide body rotatably supported by the rotating body, adjusting the angle of the rotating body and the bow guide body, The bow guide is practiced by guiding the bow.

  Alternatively, a pair of bow guide bodies B7 are erected on the main body 9 in a parallel state, and the wheels 8 are disposed between the pair of bow guide bodies B7. Playing on the wheel 8 with a bow 18 practiced bowing of the instrument.

In the present invention, since the bow guide body is provided on the rotating body, the bowing training can be performed by changing the angle of the bow.
Also, since the bow guide provided on the rotating body can rotate, the bowing training can be performed by changing the angle of the bow in the vertical direction.
When practicing with the Boeing training device of this instrument, the bow guide 12 that guides the bow 18 when bowing is attached to the main body 9, so that the bow 18 can be prevented from moving from a predetermined place during practice. Can be kept at right angles to. Further, since the bow guide body 12 is surrounded, the movement of the bow can be restricted not only in the lateral direction but also in the upward direction, so that it is possible to perform training for lifting up and strengthening when playing the violin.

Further, since the rotation of the bow guide body 12 can be locked, the hand cannot bend in any direction, and the bowing always goes straight through a predetermined position. Further, since the rotation of the bow shaft can be stopped in the through hole of the bow guide body A12 in the locked state, there is also a right hand stretching effect.
If you practice with this practice device, you can learn the exact Boeing in your body.

  Also, since there is almost no sound, you can practice without hesitation even at night.

    Embodiments of the present invention will be described below with reference to the drawings.

    As shown in FIG. 1, a main body 4 imitating the shape of a violin is formed by attaching a top plate 2 </ b> A, a front plate bottom 2 </ b> B, and a back plate 3 to an intermediate plate 1.

  A hook-and-loop fastener 6 is attached between the position where the bow passes, that is, between the upper and lower surfaces 2 and 3, and further, the hook-and-loop fastener 6 is also attached to the rotating portion B 5 (rotating body) and rotated to the center of the middle plate 1 Attach part B5. Since rotation part B5 is joined by hook-and-loop fastener 6, it can be attached or detached.

  As shown in FIG. 3, the rotating part B5 is provided with a bow guide B7 and wheels 8 on a circular base plate.

As shown in FIG. 4, a bow is inserted into the bow guide B7, and performance is practiced while the bow 18 is guided to the bow guide B7. You can practice using sticks of various weights such as wood and metal instead of bows.
When the performer bows, the bow 18 can be kept at right angles to the string in the correct position, and the bow 18 is led to the wheel 8 so that the practice of passing the violin bow perpendicular to the string can be practiced. Is possible.
FIG. 5 shows an exploded view of the rotating part B, which is composed of two bow guide bodies B 7 and wheels 8.

  Examples will be described below with reference to FIGS. As Example 2, as shown in FIG. 6, the bow 18 shown in FIG. 8 is placed at a position crossing the main body 9 imitating the violin shown in FIG. The rotating part A10 is provided with a structure in which a rotating part 11 supported by a shaft 15 and rotatable in the vertical direction is provided.

  7 is a cross-sectional view taken along the line AA of FIG. The lower part of the rotating part 11 is removed, and the rotating part 11 can rotate around the shaft 15 in the direction perpendicular to the main body 9. As shown in FIG. 6, assuming that the main body 9 is the main body A1 on the right side of the rotating portion and the main body B1 is on the left side, the main body A and the main body B are spanned and integrated with the joint member 16.

    In order to keep the rotating part A10 (rotating body) placed on the main body 9 mounted during the practice of the bowing, a hook-and-loop fastener is provided on each of the joint surfaces on the main body 9 side and the rotating part A10 side. After the joining member such as 13 is provided and the rotation portion A10 is rotated to a predetermined position, it can be detachably fixed.

  A through-hole-shaped bow guide A12 that is in contact with or integrated with the rotating portion 11 is provided, and a bow 18 is inserted into the bow guide A12 to practice bowing. The bow guide A12 has a shape that allows the bow 18 to rotate following the movement of the right hand when the bow 18 is inserted and bowed (circular is generally used).

Next, the operation will be described. The performer rotates and fixes the rotation portion A10 to a predetermined position, inserts the bow 18 into the bow guide A12, sets the rotation portion 11 at a predetermined angle, and then attaches the bow 18 to the bow guide A12. Guided by the hole, training with bowing back and forth. Thus, as shown in FIG. 8, when the performer inserts the bow 18 into the bow guide 12 and bows, the bow 18 is kept in the correct position and can be kept substantially perpendicular to the string. .
The rotating unit 11 can also perform bowing in a rotatable state.

    Further, in the embodiment shown in FIG. 6, the rotating part A10 is arranged so that the bow is perpendicular to the string. However, as shown in FIG. It can be adjusted to any angle according to the performer or performance method for the purpose of correcting habits or stretching.

  By providing the convex part 17 in the rotating part A10 and disposing a member having a pressing action between the convex part 17 and the rotating part 11, the rotation of the rotating part 11 is brought into a locked state. As a result, the hand cannot bend in any direction, and Boeing always goes straight through a predetermined position.

  A third embodiment is shown in FIG. As shown in FIG. 10, when the bow guide body A12 has a through hole formed into a square or the like and bowed with the bow 18 reduced in a similar shape to the through hole, it is impossible to follow the movement of the right hand and to rotate the bow 18. The through hole having a shape (generally other than circular) is formed.

  If the lock | rock state of the rotation part 11 is cancelled | released, it has the structure which act | operates freely and can perform normal practice.
