The quena, also written as "kena" in English, is the traditional flute of Peru and the Andes. Made of bamboo, it has six finger holes and one thumb hole and is open on both ends. To make a sound, the player closes the top end of the pipe with the flesh between the chin and lower lip, and blows a stream of air downward, over a notch cut into the end. It is normally in the key of G major. G is the lowest note when all the holes are covered. It produces a very breathy or airy tone.
