Triangulation is the result of a desire to map timbral properties to spatial relations. The piece consists of a self-contained triangular prism, 2 ft on a side and 8 inches deep. On its sides are embedded 16 IR sensors, and 2 speakers which serve as the inputs and outputs of the piece. Distance from each IR sensor is calculated using high-speed analog-to-digital converters (ADCs) which feed into a Raspberry Pi running PureData. The PureData patch interprets the sensor data as the amplitudes of a chorus of voices, which together form a sonic space that is neither major nor minor, but complex enough to expressively sculpt in the space between your hands.
