The Leqin is composed of the stem, barrel, headstock, peg and bow. The stem, headstock and pegs are all made of hardwood. The headstock of the leiqin is shovel-shaped, the surface of the pegs is engraved with patterns, and the top of the shaft is embedded with bone ornaments. The barrel of the leiqin is relatively short and is made of thin copper plate.

Its bow is longer than that of the erhu, and the ponytail tied to it is wider. In addition, there are two sizes of leiqin, the big leiqin has a steel wire string with a body length of 110 cm; the small leiqin has a 90 cm body length.

The lute is usually tuned in fourths or fifths. The tuning of the grand piano is not uniform, and it is generally determined according to the habit of the performer, and the sound range can reach three and a half octaves. The tuning and range of the violin are the same as those of the violin, except that it is pronounced an octave higher.
