The Jew's harp is thought to be one of the world's oldest musical instruments. Despite its common English name, it has no particular connection with the Jewish people or Judaism. In fact the name "Jew's Harp" is controversial and is avoided by many. This instrument is native to Asia and used in all tribes of Turkish people in Asia where it is variously referred to as a temir komuz, agiz komuzu or gubuz.
The instrument consists of a flexible metal or bamboo tongue (or reed) attached to a frame. The tongue/reed is placed in the performer's mouth and plucked with the finger to produce a note. The frame is held firmly against the performer's parted front teeth, using the jaw and mouth as a resonator. By changing the shape of the mouth and the amount of air contained in it, the performer creates different notes.
