Anotations

Scope note:

Percussion instruments known primarily in Africa and New Guinea which employ water as a resonator. The African instruments consist of a half-gourd floating upside down on water within a larger vessel; the floating gourd is struck by spoons, sticks, or the hands. The New Guinea instruments have an hourglass-shaped hollow body open at both ends, sounded by being stamped against the surface of water.
