Exploring Musical mappings and Generating Accompaniment with Chaotic Systems

Chaotic systems can exhibit a complex evolution that is well-suited to musical control. By modelling one such system, known as Chua’s circuit, a number of chaotic attractors that oscillate in rhythmic fashion were discovered, similar to traditional wave oscillators used in sound synthesis. This led to an exploration of the sonification of the system and an investigation of musical mappings such as filter control, spatial rendering, and note generation. A method of controlling musical accompaniment was also developed, where the chaotic system is used to generate melodies that conform to a key and scale specified by the user. Finally, an immersive virtual interface was designed that allows a performer to play along with the accompaniment, while controlling various high-level parameters.
