The jew's harp is a small musical instrument that is played by plucking a metal or bamboo tongue with the fingers while holding the frame against the mouth. It produces a unique twanging sound, which can be modified by changing the shape of the mouth and throat. This instrument has been used in various cultures around the world for centuries. Often associated with folk music, the jew's harp is known by different names in different regions, such as jaw harp or mouth harp. It is typically made from materials like brass, steel, or wood, and is popular for its portability and ease of use, making it accessible to musicians of all ages.
