  An embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, a main body 1 imitating a violin is divided, and a guide body sandwiched between a main body 1a of a portion where the violin is applied to the neck and the other main body 1b. A fixture 2 is attached to each of the main bodies 1a and 1b. The main body side guide body 3 is attached between the two guide body attachments 2a and 2b. The main body side guide body 3 is provided in the vertical axis direction with respect to the front plates 1c and 1d of the main bodies 1a and 1b. The main body side guide body 3 is provided between the main bodies 1a and 1b, and the position thereof corresponds to a portion where the string and the bow come into contact with each other when playing the violin. A bow guide body 11 is provided so as to be slidable in contact with the main body side guide body 3, and the bow body 4 is connected to the bow guide body 11. As shown in FIG. 3, the main body side guide body 3 and the bow guide body 11 are constituted by a pair of slide rails, and are slidably guided by the grooves of the slide rails. The bow 4 imitates the shape of a bow when playing a stringed instrument. When the bow 4 is moved in the vertical axis direction (vertical direction), the bow guide 11 integrated with the bow 4 moves while sliding with the main body guide 3. Reference numeral 5 denotes a violin neck which is integrally fixed to the main body 1b and is supported by the left hand during training. FIG. 5 is a plan view showing the relationship between the main body side guide body 3 and the bow body 4 from above. As shown in FIG. 7, the guide body fixtures 2a and 2b are inserted into support body insertion portions 10a and 10b provided in the main bodies 1a and 1b, and are attached to the main bodies 1a and 1b, respectively.

As shown in FIG. 4, nuts 8 are fixed to the main body 1a and the main body 1b. The support 9 can be fixed or released by the fixing tool 7.

Next, the operation will be described. At the time of training, as shown in FIG. 1 or FIG. 6, the front plate 1c of the main body 1a is sandwiched between the neck and chin, and the violin is fixed by holding the neck 5 with the left hand. In this state, the right side portion of the bow 4 is held with the right hand, and the bow 4 is moved in the vertical axis direction, that is, in the vertical direction with respect to the bows 1c and 1d. At this time, the bow 4 moves only in one direction by the guides of the bow guide 11 and the main body side guide 3. It is desirable to select a material having a small frictional force between the bow guide 11 and the main body side guide 3 in order to make a smooth movement. Further, it is desirable that the bow guide body guide 11 and the main body side guide body 3 are configured so that the bow body 4 does not move in the front-rear and left-right directions in FIG. 1 so that the bow body 4 moves only in the vertical direction.

After the trainee determines the angle of the bow guide 11, the training can be performed with the fixing tool 7 locked, or the fixing tool 7 can be unlocked while changing the angle of the bow 4 in a free state. Do. This training stabilizes the angle between the bow and the violin, and training that plays with minimal changes in the placement of the bow hair makes the sound stable.

In order to play with clean sound, it is not enough to play with the bow crossing the string at right angles in two dimensions. In three dimensions, it is also important to apply pressure in the direction of force insertion in the direction perpendicular to the string.

Further, as shown in FIG. 11, the gripping member 14 is provided so as to freely slide on the outer periphery of the bow body 4.

As shown in FIG. 11, the gripping member 14 is held and slid freely along the arch, and is slid by the gripping member 14 in the direction of the movement of the bow. The side guide 3 can be slid to perform training.

Moreover, the cross-sectional shape of the arch body and the gripping member 14 may be a shape other than a perfect circle, such as a polygon, which restricts the rotation of the gripping portion 14.

At least one of the gripping member 14 and the arch 4 is formed of a rail having a slide function, and training can be performed while sliding.

Violin, viola, cello, and contrabass bow hairs consist of multiple hair bundles (horse tails). A string is rubbed with a bunch of hair stretched around a bow. However, when rubbing a string with a bow, it is often the case that force is inserted in an unintended direction, which causes the arrangement of the hair bundle portion to collapse and the tone to become unstable. Therefore, in order to produce a clean sound with the violin, it is desirable that the direction of force insertion when the violin string is rubbed with a bow is always constant in the direction of the vertical axis with respect to the surface plate of the violin. In the present invention, the insertion direction of force is memorized in an arm, a hand, or a finger. In addition, since the support shaft 9 of the guide body fixture 2 is held so as to be capable of rotating, the guide body such as a slide rail is inserted into the string while maintaining the insertion angle of the force at a right angle to the surface plate of the violin. The axis can be rotated around the direction axis, and all strings can be practiced.

FIG. 12 shows a second embodiment. There are split bodies 15a and 15b that can be split. The divided body is provided with divided body openings 16a and 16b.
