The dahu (大 胡, pinyin: dàhú) is a large bowed string instrument from China. It has a large soundbox covered on one end with python skin. Like most other members of the huqin family of instruments, it has two strings and is held vertically. The instrument is generally pitched one octave below the erhu, and is considerably larger than the erhu. Its name derives from the Chinese word for "large" (dà), and the word hú (short for huqin). Its bridge is often placed somewhat above the center of the snakeskin to avoid stretching the skin.
