The Vitrophone is an instrument as well as a sculpture. It consists of strangely shaped glass shards, which are tuned on tone.
Modeled to the broken pond, the shards rest on wooden legs so they can freely resonate. The Vitrophone has a bright sound, somewhat similar to a xylophone.
The arrangement in tune of the shards is not based on the regular order in instruments, but rather composed as a shape.
A special composition, written for two percussionists, is based on note sequences that forces them to move around the instruments, in opposite direction. Thus creating a choreography in sound.
