The zhonghu (中胡, pinyin: zhōnghú) is a low-pitched Chinese bowed string instrument. It is a member of the huqin family together with the erhu and gaohu, and was developed in the 20th century as the alto member of the huqin family (similar to the European viola) to be used in orchestras of Chinese traditional instruments.
The zhonghu is the same as the erhu but is slightly larger and is 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 (this latter tuning equivalent to the violin's lowest two strings).
