The ''jing erhu'' is a Chinese two-stringed bowed instrument in the ''huqin'' family of instruments, similar to the ''erhu''. It is so named because it is used in ''jing xi'', or Beijing opera. It is lower in pitch than the ''jinghu'', which is the leading melodic instrument in the Beijing opera orchestra, and is considered a supporting instrument to the ''jinghu''.
The ''jing erhu'' has a wooden body and neck. It is played vertically, with the body resting on the player's left thigh and the horsehair of the bow passing between the two strings. It previously used silk strings, but since the 1960s has more commonly used steel strings.
The ''jing erhu'' was popularized in the 1920s by Wang Shaoqing , a musician in the troupe of Mei Lanfang.
