Lead: Yueqin, a plucked instrument of the Han nationality, originated in the Han Dynasty. The speaker is full of circles and the neck is short. The following is an introduction to the knowledge of Qin Yue structure that I have carefully arranged for you. Welcome to refer to!
The structure of the piano is similar to that of Ruan, but the difference is that the piano body has sound beams and columns, and the neck is short. Yueqin consists of a piano head, a piano neck, a piano body, a piano shaft, strings and strings.
The head and neck of a piano are made of a whole piece of rosewood or other hardwood. The decoration on the top of the piano head is carved into a faucet or other patterns from wood alone, and then glued on. The upper part of the neck is provided with a chord groove, and the side of the groove is provided with a round hole for installing the chord shaft. There is a square wooden pole at the lower end of the neck.
The piano body is an oblate resonance box, which is made by gluing the face, back and frame plates. The frame plate is made of 6 pieces of wood glue with the same specification to form a round piano frame, and there are holes for putting square wood up and down the neck. Its two sides are adhered to the surface and back plate. The front panel and the back panel are castanets with yueqin pronunciation, made of paulownia, with straight and uniform texture, no scars and consistent wood color. Two sound beams are horizontally arranged between the front and rear plates, and two sound columns are supported in the middle.
The string is boxwood, the outer surface is engraved with oblique petals, and the twisted end is also embedded with ivory or bone ornaments.
The strings are made of silk, nylon strings or steel strings wrapped in nylon. Nylon wire and steel wire have the best effect.
The binding wire is made of mahogany or bamboo and stuck in the middle of the lower part of the panel.
High-quality Qin Yue, accurate scale, pitch deviation less than+15 points, crisp and soft tone, wide and bright voice; The roundness of the piano body is accurate, the width of the frame plate is consistent, and the back plate is flat and clean; The piano head is finely carved; Accurate intervals and orderly arrangement; The neck and the panel are in the same plane, and there is no phenomenon of leaning forward or backward; The chord shaft is closely matched with the shaft hole, and the gear copper shaft is sensitive. All glued parts are firmly spliced and painted evenly and brightly.
Holding the string with the left hand and playing the Qin Yue with the right hand has developed into more than 30 techniques such as playing, plucking, pinching, rolling, sweeping, pressing, trembling, sliding and reciting, among which the unique "scraping" method can be used not only for accompaniment, but also as an excellent solo instrument.
