Erhu is a very famous stringed instrument in China. Its history can be traced back to the Tang dynasty from the 7th to 10th century AD. It was welcomed among the ethnic people of the northeastern part of China. Erhu has long been the accompanying instrument in traditional dramas.

The structure is quite simple. There is a slim neck about 80 centimeters, on the surface of which two strings are fixed. In addition, there is a cup-shaped canister and a bow made of horse hair. While performing, the musician is usually seated, with the organ and bow held in the left and right hand respectively. The range consists of three octaves. The tone is close to the human voice. Some people call it the Chinese violin. Because the tone sounds somewhat melancholy, it is good at conveying sad emotions.

The making, renovation and performing skills of erhu have been greatly improved since 1949. It can be used to play solos, accompany opera and traditional dramas. In the ethnic orchestra, erhu even plays the leading role, just as the violin does in western orchestras.

Erhu is highly popular with the Chinese people because of its simple design and low cost. It is welcomed in nearly all Chinese families.
