Zhonghu

The zhonghu is a low-pitched Chinese bowed string instrument. Together with the erhu and gaohu, it is a member of the huqin family, and was developed in the 20th century as the alto member of the huqin family. The zhonghu is analogous with the erhu, but is slightly larger and lower pitched. Its body is covered on the playing end with snakeskin. The instrument has two strings, which are generally tuned to the interval of a fifth, to A and E or to G and D.
