Gaohu
From Wiki China org cn
Gaohu, also called High-pitched erhu or yuehu, is especially designed for playing Cantonese folk melodies and operas. Gaohu is often used for performing vivid and brisk rhythms, particularly for higher-pitched tunes that erhu cannot play. In comparison with erhu, Gaohu has louder volume yet brighter tones, and thus it servers both as solo and leading instrument in performing Cantonese operas and folk melodies.
