The jaw harp, also known as a Jew's harp, is one of the oldest musical instruments in the world, with archaeological evidence dating back thousands of years. It is a lamellophone, meaning it produces sound through the vibration of a thin reed or tongue. The instrument is played by placing it against the player's teeth or mouth and plucking the reed, with the player's mouth cavity acting as a resonator to shape the sound.
