Jew’s harp
Considered one of the oldest music instruments, the Jew’s Harp, Jaw Harp or Mouth Harp is a pretty strange instrument due to its form and to to the fact that you use your moth to play it but your fingers do all the work.
Originating from the lamellophone category, this music instrument has a difficult past to track, because it has been used from ancient times, by many nations.
Featured in many historical mentions, drawings, or paintings the piece is made out of a flexible metal which is attached to a frame.
The tongue is possible to be made also from bamboo and it’s purpose is to be plucked in order to make music.
The flexible tongue resonates with the mouth and with the positioning of the teeth, making harp like sounds from the vibrations of the reed.
