高胡，高音二胡的简称，又叫粤胡，是一种弓弦乐器，于1920年代由司徒梦岩及其学生吕文成创制，取代了二弦的位置，成为广东音乐和粤剧的主要伴奏乐器。

高胡的琴筒比二胡小，皮膜和音窗通常是圆形，定弦是G4到D5，比二胡高四度。高胡是坐着演奏，大腿夹住皮膜和音窗以控制音色、音量，并能减少狼音。演奏时皮膜向右，弓毛置于两弦之间，弓杆置于外侧。高胡的音色比二胡清澈明丽，因此常用于演奏欢快明媚的曲。

高胡原用于广东音乐，为满足模仿管弦乐团的民乐团对高音域弓弦乐器的需求，与二胡、中胡、板胡、大提琴（或革胡）和低音提琴（或低音革胡）组成弓弦乐器组。

The gaohu (高胡; pinyin: gāohú, pronounced [kɑ́ʊ̯xǔ]; Cantonese: gou1 wu4; also called yuehu 粤 胡) is a Chinese bowed string instrument developed from the erhu in the 1920s by the musician and composer Lü Wencheng (1898–1981) and used in Cantonese music and Cantonese opera. It belongs to the huqin family of instruments, together with the zhonghu, erhu, banhu, jinghu, and sihu; its name means "high-pitched huqin". It is the leading instrument of Cantonese music and opera ensembles. Well known pieces for the gaohu include Bu Bu Gao (步步高, Higher Step By Step) and Ping Hu Qiu Yue (平湖秋月, Autumn Moon on Calm Lake).
