Tremolo-Chimes

The Tremolo-Chimes is an interactive performance system that consists of a set of tubular metallic wind chimes that have been modified by removing the striker and wind catcher. MIDI-controlled vibration motors suspended in each chime produce continuous, tremolo-like sounds where the dynamic shape can be controlled over time. This system is inspired by acoustic wind chimes and explores questions about performative agency in automated instruments. The Tremolo-Chimes interactive installation employs multiple control methods, including synthesized wind and sensors that detect the proximity of participants to the chimes. Both synthesized wind and sensor input are fed through a mass-link physical model, evoking the movements of a wind-driven clapper bouncing off traditional wind chimes. Synthesized wind represents the default control mode of the installation when participants are not interacting with the sensors. When a participant enters the sensing field, their body will actuate the chimes similarly to how a percussionist uses their hand to sweep across a set of chimes.
