Kouxian (Chinese: 口弦; pinyin: kǒuxián; lit. 'mouth string') is a general Chinese term for any variety of jaw harp. The jaw harp is a plucked idiophone in which the lamella is mounted in a small frame, and the player's open mouth serves as a resonance chamber.
Chinese jaw harps may comprise multiple idiophones that are lashed together at one end and spread in a fan formation. They may be made from bamboo or a metal alloy, such as brass. Modern kouxian with three or more idiophones might be tuned to the first few tones of the minor pentatonic scale.
