Quena & quenacho

Is the traditional flute of the Andes. Usually made of bamboo, it has 6 finger holes and one thumb hole and 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. It is normally in the key of G, with G being the lowest note (all holes covered)

The Quenacho (also "kenacho" in English) is a larger, lower-toned version of the quena and made the same way. It is in the key of D, a fifth lower than the quena.
