This Demonstration uses a simple and novel mapping of elementary cellular automata (CA) to single-voice musical sequences. The mapping is created by evolving a small CA through all its possible initial conditions for a number of generations, converting the cells to decimals and storing them in a table. This table is visualized using Mathematica's built-in function ArrayPlot with starting conditions assigned vertically and generations evolving horizontally.
These example sound pieces were tested on a Mac using the internal default sound sample set; the sounds available will depend on your platform. The change in ArrayPlot size depend on the number of cells and generations specified.
