The left end of the strings is tied to the rocker through the resonance tube, the strings are about 6 cm away from the piano surface, and the right end passes through the string hole and is wound on the peg at the bottom of the piano. Play with a bamboo stick.

Since the 1960s, the bamboo monochord has been reformed, and the bottom plate and the first and last frame plates have been added to make it a resonance box, and the harmonic position is marked on the surface like a guqin. Some also add a wooden fingerboard on the surface of the piano. There are 16 frets embedded on the fingerboard, which can make the strings emit more real tones, and can play overtones more quickly, which enriches the playing skills of the solo stringed piano.

The solo qin was originally only used to accompany poets to recite poems, and later developed to accompany songs and dances or to accompany other musical instruments (especially with the dongxiao).

In ethnic bands, the lyre is often used as a color instrument. The monochord is an overtone musical instrument with a unique playing technique. It can play two notes on one string at the same time. The tone is soft and beautiful, and it is suitable for expressing long and lyrical melody.

The single-stringed qin is a favorite folk musical instrument of the Jing people. Whether it is a festival or a slack season, people will sing improvised folk songs with its accompaniment. Because its pronunciation is very similar to Jing folk songs, and the decorative sounds are full of singing charm, when accompanying folk songs, the sound of the qin and the singing blend together, and the two are integrated. The solo string is not only a beautiful solo instrument, but also an excellent accompaniment instrument. It can also participate in ensemble or ensemble. In ethnic bands, the solo string is often used as a colorful instrument.
