Native American flutes differ greatly from other types of flutes because they use two air chambers to achieve their signature sound. A wall inside the flute creates a top and bottom air chambers. The bottom air chamber provides the bulk of the sound and tone due to its direct connection with the whistle and finger holes. The special top chamber serves as a resonator.
Native American flutes were originally played without accompaniment for a variety of tribal rituals. In modern times, it is not uncommon for Native American flutes to be played with other instruments and vocals as a part of a variety of musical genres.
