[0002]

2. Description of the Related Art Conventionally, in the field of Western musical instruments, for example, a harp, a lira, a guitar, a mandolin, a banjo, a ukulele, and a chiter have been used as stringed instruments used to express music by plucking a string with a fingertip or a pick. Known,
The harp is composed of a large number of open strings to form a scale, and plucked strings are used to express music with a beautiful sound. The lyre is arranged so that a rod is placed above a U-shaped or V-shaped frame, and 4 to 7 strings are provided between the frame and the bar so that the plucked string can be played. Guitars, mandolins, banjos, and ukuleles all have 4-8 strings attached to the body of the instrument, which consists of a resonance box made of wood and a rod, and at least 12 frets attached to the rod. It is structured so that it can be played by pressing the strings with the finger of the left hand and plucking the strings with the fingertip of the right hand or a pick. On the flat box-shaped instrument body, the chita is responsible for 5-7 melodic strings and a large number of frets, as well as 10 rhythms and harmonies.
It is equipped with about 40 accompaniment strings. The left and right fingers hold the strings together and the right thumb (with a pick) plucks the melody strings, and the remaining fingers pluck the accompaniment strings. It produces a hard, clear, high-pitched sound, and the accompaniment strings are constructed to give a soft, calm and warm sound.

On the other hand, in the field of Japanese music, Koto, Taisho Koto, Shamisen, Biwa, etc. are known. Koto has 13 strings attached to the upper surface of a hollow cylinder made by sticking long paulownia boards, and a koto pillar and a string. It is tuned by interposing between and, and is configured so that it can be performed by holding down the strings by the finger of the left hand and plucking the strings by the artificial nail attached to the fingertip of the right hand. Taisho koto is a hollow body made of wood, etc. 2
It is a stringed book, equipped with a simple keyboard, and is designed to pluck and play using the prosthesis. Further, the shamisen is constructed such that three strings are stretched on the main body of a musical instrument consisting of a body with a skin of a cat or the like stretched on both sides and a long rod, and the strings are plucked and played. Biwa is usually composed of an eggplant-shaped flat barrel made of wood and has four strings attached to the body of the musical instrument, and four pieces are attached to the handle. It is configured to pluck and play.
