Anotations

Scope note:

Native American duct flutes traditionally made of wood or cane, in which the bore is blocked by a partition which forces the airstream out through a hole where an external block, normally of wood tied on to the tube, channels the air along the exterior of the tube to a second hole where it impinges on the voicing edge; traditionally used as a man's solo courting instrument.
