Abstract:
|
In this paper, I describe three experiments with complex systems concepts and the emergence of music from noise. The first program uses a chemical reaction simulation to create musical interactions between progressions in several musical keys and cellular automata (CA) within the regions containing the chemical elements. The second program is an applet which generates music within a single key and outputs the state of the CA system as a phase state plot and as audio. The third experiment, related to work by Bilotta [1], modifies the transition rules of a CA with genetic algorithms (GA) to allow more sophisticated structures to arise. Keeping the four classes of CA identified by Wolfram [2] in mind, a person is able to observe several compromises between convergence and divergence. These methods of harmonization would be useful in creating accompanying audio in a live performance situation as well as stand alone compositions. By using several applets, animations, and other techniques described by Johnson [3] to visualize CA systems and other music generation tools, I endeavor to share my process for post-modern music generation during live video jockey (VJ) performances as well as through my web site, http://www.rustcycle.com.
