Huqin [in Mandarin Chinese: 胡琴; pinyin: húqín] is a family of bowed string instruments, more specifically, a spike fiddle popularly used in Chinese music. The instruments consist of a round, hexagonal, or octagonal sound box at the bottom with a neck attached that protrudes upwards. They typically have eight strings except the sihu, which has four strings tuned in pairs.
The huqin resonator or body are typically covered with either snakeskin [most often python] or thin wood such as the banhu. Huqin instruments have either two [or, more rarely, four] tuning pegs, one peg for each string. The pegs are attached horizontally through holes drilled in the instrument’s neck. Most huqin have the bow hair pass in between the strings.
