The kèn is an instrument used in traditional Vietnamese music. It has a double reed and a conical wooden body. It produces a powerful and penetrating high-pitched sound, similar to the Chinese suona, the Korean taepyeongso, and the Persian/Indian shehnai.
The best-known player of the kèn is the award-winning musician Nguyễn Ngọc Khánh (b. 1956), who is acknowledged as a "national treasure" in Vietnam, where he is known as "Khánh of the kèn."
