Eye-Height is a choreographic work that activates a scenographic/instrumental object. This object is a ‘stage instrument’ of six metres squared, made from nine wooden modules, with an undulated variable surface, forty to seventy-five centimetres thick. Dancers perform improvised movement within a choreographed structure on the surface of the object, which behaves as a resonance box for sounds that are created by the friction and percussion of moving bodies on its surface. The vibration induced by the dancers activates nine sets of tuned piano strings inside the stage instrument. The structure of the device articulates conceptually the qualities present in the choreography. Eye-Height creates an extensive landscape of performers (dancers and musicians), audience, and space. As suggested by the title, the spectator’s eye is at the same height as the stage-object. The sound produced by the dancers interacts with the live music; Musicians and dancers share the same gestural and sound premisses of the common scores.
