Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a string instrument piece used for changing the vibration length of each string of a string instrument such as a guitar.
[0002]
[Problems to be solved by the invention]
In general, the guitar produces sounds other than open strings by holding the strings on the frets with fingers and changing the vibration length of the strings to the desired length. For this reason, there is a drawback that it is difficult for children who are weak, for example, to perform.
An object of the present invention is to provide a stringed musical instrument piece that can be set so that even a weak child can play a simple song in an open string state without restraining the string.
[0003]
[Means for Solving the Problems]
In this invention, it has almost the same length as the interval in the arrangement direction of the strings of the guitar, and can be set to a different fret position for each string, and the vibration length of the string is changed by contacting the string at each set position. It proposes a string instrument piece.
By using the stringed instrument piece according to the present invention, it is possible to generate a sound that is not found in an ordinary guitar even in an open string state, that is, without holding the string against the fret with a finger. Accordingly, if the string instrument piece according to the present invention is set to an appropriate fret position and the string is vibrated in an open string state, the target music can be played. Therefore, the child can also practice the guitar.

DETAILED DESCRIPTION OF THE INVENTION
1 and 2 show a stringed instrument piece according to the present invention. In the figure, reference numeral 10 denotes a stringed instrument piece according to the present invention. The present invention proposes a string instrument piece that can freely change the sound of the open string of each string by engaging different fret positions for each string of the string instrument. For this reason, the string instrument piece 10 according to the present invention has a dimension W (see FIGS. 1 and 2) substantially equal to the arrangement pitch P of the strings 20 (see FIG. 3) of the target stringed instrument and a direction orthogonal to the direction in which the dimension W is given. A bottom surface 11 having a dimension L larger than the dimension W, a groove 12 formed at a substantially central portion of the bottom surface 11 in the direction of the dimension L, and a protrusion 13 formed at a position directly above the groove 12. Configured.
[0005]
The bottom surface 11 is placed on the surface of the guitar fingerboard 22 (see FIGS. 3 and 4), the guitar fret 21 is engaged with the groove 12, and the dimension L is arranged in a direction parallel to the string 20. The height of the protrusion 13 from the bottom surface 11 is selected to be larger than the gap G (see FIG. 4) between the surface of the finger plate 22 and the string 20.
The fingerboard 22 is attached to the flat portion of the neck 23 protruding from the guitar body, and is arranged in parallel with the string 20.
[0006]
In this embodiment, a semicircular recess 15A is formed on one end face 15 in the direction in which the dimension W is given, and a semicircular protrusion 16A is formed on the other end face 16 (see FIG. 2). These concave portions 15A and projections 16A are used when connecting adjacent pieces when they are connected to each other as shown in FIG. Further, when one of the pieces 10 is independently arranged by forming the protrusion 16A to protrude, the dimension ΔW of the protrusion 16A is added to the dimension W. Therefore, by forming the protrusion 16A to protrude, The supporting force for the string 20 can be stabilized.
[0007]
In addition, since the projection 16A is formed in this way, when the piece 10 is engaged with the chord 20 at the end, the projection 16A is formed when the piece 10 is arranged in the direction in which the projection 16A protrudes toward the end. The string 20 may be engaged with the groove 14A on the side close to the protrusion 16A so as not to protrude from the finger plate 22.
By engaging and setting the fret 21 in the groove 12 of the piece 10 and placing it on the fingerboard 22, the protrusion 13 is positioned directly above the fret 21. Therefore, the groove 14 </ b> A or 14 </ b> B formed in the protrusion 13 is formed. By engaging the string 20 with the frame 20, the vibration length of the string 20 defined by the piece 10 becomes equivalent to the vibration length defined by the fret engaged with the groove 12. Therefore, by setting the piece 10 to the position of each fret 21, the vibration of the string 20 defined by the piece 10 is changed to a sound determined by the position of the fret 21 where the piece 10 is set. As a result, by setting the piece 10 to the position of an arbitrary fret 21, it is possible to generate a sound that is not found in the open string of a general guitar by playing the open string.
[0008]
FIG. 6 shows another embodiment of the present invention. In this embodiment, a case is shown in which the piece 10 is configured using a triangular prism. By forming the grooves 12 on each surface of the triangular prismatic body, the piece 10 can be placed on the fingerboard 22 without selecting the direction in which it is placed.
FIG. 7 shows still another embodiment of the present invention. This embodiment shows a case where the groove 14 for engaging the string 20 is formed deep and the engagement state between the string 20 and the piece 10 is kept stable.
[0009]
【The invention's effect】
As described above, according to the present invention, the piece 10 can be set at different positions with respect to the strings 20 of the guitar as shown in FIG. Therefore, by setting the piece 10 to the position of the arbitrary fret 21, even if each string is played with an open string, a sound that cannot be obtained with a general guitar can be obtained. As a result, by selecting the set position of the piece 10 appropriately and selecting the order in which the set sounds are played appropriately, it is possible to play a simple tune even with the open string playing method, that is, without suppressing the string to the fret. Can do. The example shown in FIG. 8 is a pentatonic scale (doremisolado) in E major, which is a scale adopted for many songs. By setting to the state of FIG. 8, many melody can be obtained only by playing an open string, without pushing a string. As a result, it is possible to obtain an actual benefit that even a weak child can play the guitar.
