Playing the Water Gurgle Flute

This is one of a series of Agitation Flutes I’ve made. Agitation Flutes are instruments in which a broad-spectrum noise with no clear frequency is introduced into a flute-like air column. The air column selects for and reinforces its own natural frequency. The ear recognizes the air-column pitch, but the tone is still awash in the surrounding noise. In the Water Gurgle Flute, the turbulence is a bubbling water sound: the player blows through a tube into a reservoir at the bottom of a small enclosed vessel. The open end of the flute extends into the vessel from above. A tiny microphone picks up the resonated tone within the air column.
