Acoustics Based on Volume:
Aluminium
A sphere, a cube and a tetrahedron: three objects made of aluminium, all constructed to contain the same volume. Together they form a new instrument which shows how form changes its acoustic character by using its individual resonance. With the use of electronics, the shapes can be used as instruments or acoustic (reverb) chambers. A work made for both performance and research, with an interest in the language of bodies.
