đàn gáo is a bowed string instrument a part of the traditional Vietnamese orchestra. The instrument originated from South Viet Nam, and is used in entertainment contexts. It can be played alone, as part of an orchestra, or to accompany cải lương (Vietnamese folk opera). The instrument’s name can be broken down as “đàn” meaning string instrument, and “gáo” literally translated as an aged coconut shell used as a scooper. The đàn gáo is most closely related to the yehu and banhu in Chinese culture, and the fiddle in Anglo-American culture.
