Coupled Map Lattices as Musical Instruments

We use one-dimensional coupled lattice maps (CMLs) to generate sounds that reflect spatial organization and temporal evolution of these dynamics started from a random initial configuration corresponding to uncorrelated noise. In many instances, the process approaches an equilibrium, which generates a sustained tone. The pitch of this tone is proportional to the lattice size, so the CML behaves like an instrument that could be tuned. Among exceptional cases, we give an example with a metastable strange attractor, which produces an evolving sound reminiscent of drone music.
