Page "Washtub bass" Paragraph 4

Ethnomusicologists trace the origins of the instrument to the ' ground harp ' - a version that uses a piece of bark or an animal skin stretched over a pit as a resonator.

The ang-bindi made by the Baka people of the Congo is but one example of this instrument found among tribal societies in Africa and Southeast Asia, and it lends its name to the generic term inbindi for all related instruments.

Evolution of design, including the use of more portable resonators, has led to many variations, such as the dan bau ( Vietnam ) and gopichand ( India ), and more recently, the " electric one-string ", which amplifies the sound using a pickup.
