The sound sculpture Tuned Volume is a spherical modular wooden structure that reproduces the harmonic frequencies of the acoustic standing waves of the room where the sculpture is exhibited. The massive presence of the sculpture thus transforms the spatial perception of the room, but it is also in harmonious relation with the surrounding space through the sound waves tuned into the room’s frequencies. Sound hence correlates the architectonic and acoustic properties of the room, with the sculpture’s volume and resonant mass.
