Flutes are aerophones. An aerophone (/ËÉÉroÊfoÊn/) is any musical instrument that produces sound primarily by causing a body of air to vibrate, without the use of strings or membranes, and without the vibration of the instrument itself adding considerably to the sound. Aerophones categorically comprise the largest and most complex group of instruments in the Americas.
