The jaw harp, also known as a mouth harp or Jew’s harp, is a musical instrument that is played by placing it in the mouth and plucking the tongue with one hand while modifying the shape of the oral cavity with the other. The resulting sound is a buzzing or twanging noise that can be varied in pitch and timbre by changing the position of the tongue and mouth.
Jaw harps have been found in archaeological sites dating back to the Bronze Age, and they are still played in many cultures around the world. They are often used in folk and traditional music, and they can also be used to create sound effects in film and television.
