AboutRelay Rhythms is an interactive tabletop sound sculpture made from salvaged industrial relays and custom circuitry. The relays click in polyrhythmic relationships based on their control knobs, and send corresponding signals to a computer. These signals act as excitation pulses for a set of synthetic waveguides which are controlled by hotkeys on the computer keyboard. In this configuration, the sculpture and computer work together to create an instrument. The sculpture contributes energy to initiate resonance in the waveguides, and the parameters of the waveguides are played in real time.
