Three Piece is a three piece ‘band’ - two guitars and a bass guitar. The sound is generated by moving them around, so the air gently plays the strings of the instruments. The speaker is located on the other end of the installation.
Visitors are encouraged to walk between the instruments (but don’t come too close to the moving arms!). The sound of this installation created by Stephen Cornford can best be described as a haunting soundscape.
