The ancient lyre has wide range of sound, deep timbre and long lingering sound. 11/7/2003, the world heritage committee of the national academy of education announced that the chinese guqin was selected as the world cultural heritage. Listed in the Chinese non-material culture heritage list in 2006.
The guqin is a long and narrow wood stringed instrument, and generally comprises a surface, strings, a hui, a Yueshan, a fly head, a bottom, a dragon pool, a marsh, goose feet, a tuning peg pool, a tuning peg and the like. The ancient lyre style that passes today is just basically stereotyped in the last year of eastern Han, and its style system is: the body is usually about 120 cm long, about 20 cm wide and about 6 cm thick, and is composed of a bottom plate and a face plate, namely Jatropha curcas bottom catalpa. Gouging out the piano surface by tung wood or fir wood, gouging out the piano surface into an arc of about 60 degrees, and gouging out the piano surface into a groove abdomen; then a flat catalpa wood, a mahogany, alder or other miscellaneous trees are used as a base plate, the piano surface and the base plate are glued together to form a resonance box, then various accessories are installed, the resonance box is polished and formed, a layer of hard and heavy lacquer ash is coated, the resonance box is thoroughly dried and polished, and the lacquer coat is a thin lacquer coat, thus obtaining the traditional ancient lyre.
The gamut of the guqin is four octaves and two tones. Seven scattered tones, ninety one overtone and one hundred forty-seven every cent are included. The sound of the guqin is very unique, and a person listening to the guqin can feel the silence of the guqin.
