A musical instrument known as a mouth harp, jaw harp, juice harp, or Jew's harp. Made of copper alloy shaped with a circular end and two parallel sticks. The 'tongue' piece is missing.
The mouth harp is a type of instrument called a 'lamellophone' which produces music by flicking the small 'tongue' that is unfortunately missing in this example. Variations can be found across the world like the Cambodian angkouch, the Sicilian marranzanu, and the Nepalese murchunga.
