Idiophones: Instruments made of vibrating materials

The "Glocken-Spiel"!

Once set vibrating, idiophones ("self-playing instruments") independently continue to play themselves. Both the material the instrument is made of and the method of playing exert considerable influence on the sound - from shaking a rattle to rubbing a glass harmonica to striking two stones against each other. "Found objects" that work as self-playing instruments were most likely the first instruments known to mankind.
