The basic structure of the erhu:
The piano tube is an important part of the erhu. Through the push and pull movement of the bow, the strings are rubbed and the piano skin is vibrated to produce the sound. The texture and shape of the piano barrel have a direct impact on the volume and sound quality. Generally made of rosewood or mahogany. The shapes include hexagon, octagon, circle, front octagon and back circle, etc. The most commonly used is hexagon. There is a sound window (usually a carved wood window) inlaid behind the piano tube, which not only decorates the piano tube, but also has certain benefits for pronunciation, sound transmission and sound filtering. Qintong is the main sounding tube of Erhu.
Generally made of ebony, mahogany (red sandalwood is rare), and also made of rosewood or bamboo. In the 1970s, low-foaming (ABS) materials began to be used for molding. Its shape is mainly hexagonal, 13 cm long, and 8.8 cm in diameter at the front opening (opposite side). In some areas, it is made into a round or octagonal shape. The waist of the tube is slightly thin, and the rear mouth of the tube is open or equipped with a sound window with various patterns of holes. The piano tube plays a role in amplifying and exaggerating the vibration of the strings.
