Abstract: Chua's circuit can produce a very rich variety of signals, both periodic and chaotic. We explore some classes of these attractors with respect to their auditory display and musical properties. We discuss the fast control of the circuit through a specially developed computer-controlled electronic resistor and how chaotic control methods might be applied to optimally switch between different attractors. The Chua circuit has parameter regions where noisy frequency and amplitude modulated sounds are generated, each of which is related to a certain transition to chaos. We discovered a period-adding sequence of bassoon-like sounds that produces interesting almost-harmonic pitch changes. Finally we emphasize the importance of transient dynamics, especially in the context of percussion-like sounds.
