The Bistable Resonator Cymbal: An Actuated Acoustic Instrument Displaying Physical Audio Effects

Piepenbrink, Andrew and Wright, Matthew

Proceedings of the International Conference on New Interfaces for Musical Expression

We present the Bistable Resonator Cymbal, a type of actuated acoustic instrument which augments a conventional cymbal with feedback-induced resonance. The system largely employs standard, commercially-available sound reinforcement and signal processing hardware and software, and no permanent modifications to the cymbal are needed. Several types of cymbals may be used, each capable of producing a number of physical audio effects. Cymbal acoustics, implementation, stability issues, interaction behavior, and sonic results are discussed.
