The piano barrel is an important part of the erhu. Through the push-pull movement of the bow, it vibrates the singing body of the piano skin after wiping the strings. The texture and shape of piano barrel have a direct impact on the volume and sound quality. Generally made of rosewood or mahogany. Shapes are hexagonal, octagonal, round, front octagonal and back round. Hexagons are commonly used.

There is a sound window (usually a carved wooden window) embedded in the back of the barrel, which not only plays a decorative role in the barrel, but also has certain benefits for pronunciation, sound transmission and sound filtering. The violin tube is the * * * sounding tube of erhu, which is generally made of ebony and mahogany (rosewood is rare), and also made of rosewood or bamboo. In the 1970s, low foaming (ABS) materials were used for molding.

Its shape is mainly hexagonal, its length is 13 cm, and its front mouth diameter (opposite side) is 8.8 cm. In some areas, it is round or octagonal. The waist of the barrel is slightly thinner, and the back of the barrel is open or equipped with sound windows with various flower holes. The piano barrel plays the role of amplifying and rendering the vibration of strings.

Sound pad

Under the piano code, a small pad made of flannel or felt must be stuffed between the strings and the leather membrane, which can solve the "wolf sound" of the erhu, eliminate the empty sound of the erhu and make it concentrated and full. The thickness and size of the pad should be moderate, too thick will affect the volume, too thin will not work.

The materials for making sound pads are often white sponge, woolen cloth, cashmere, cotton cloth, suede, flannel and so on. Sponge and woolen cloth are widely used, and the best effect is natural suede, which should not be underestimated. It also has the ability to quickly change the timbre: close to the piano code, the timbre is very moist, and at the same time it will lose some volume; Away from the piano code, the timbre will become bright and bright, and it should be adjusted according to the needs of music.
