The quena (quechua: qina, sometimes also written kena in English) is the traditional flute of the Andes. Usually made of bamboo, it has 6 finger holes and one thumb hole and it is open on both ends. To produce sound, the player closes the top end of the pipe with the flesh between his chin and lower lip, and blows a stream of air downward, along the axis of the pipe, over an elliptical notch cut into the end.
