Like most of its relatives, the jinghu has 2 strings that are customarily tuned to the interval of a 5th which the hair of the non-detachable bow passes in between. The strings were formerly made of silk, but in modern times are increasingly made of steel or nylon. Unlike other huqin instruments (erhu, gaohu, zhonghu, etc.) it is made of bamboo. Its cylindrical soundbox is covered with snakeskin on the front (playing) end, which forms a taut drum on which the bridge rests, sandwiched between the drum and the strings, which are connected to a peg at the bottom of the soundbox.
