Despite the Jew's harp's name, there's no apparent historical connection with Judaism. Many older cultures fashioned it out of bamboo, while metal bow-shaped versions came from throughout Europe and Asia. It's one of the oldest known instruments, and is traditional to cultures around the world.
The instrument is made of a flexible "tongue" attached to a frame. To play it, you place the tongue in your mouth and pluck it with your fingers. It then resonates against your jaw for greater volume. You change the pitch of the note by changing the shape of your mouth as you pluck the tongue.
Also Known As: juice harp, jaw harp, mouth harp, Ozark harp, marranzano pancake
