- abstract = "Music evolves as composers, performers, and consumers favour some musical variants over others. To investigate the role of consumer selection, we constructed a Darwinian music engine consisting of a population of short audio loops that sexually reproduce and mutate. This population evolved for 2513 generations under the selective influence of 6931 consumers who rated the loop aesthetic qualities. We found that the loops quickly evolved into music attributable, in part, to the evolution of aesthetically pleasing chords and rhythms. Later, however, evolution slowed. Applying the Price equation \cite{price:nature}, a general description of evolutionary processes, we found that this stasis was mostly attributable to a decrease in the fidelity of [genetic] transmission. Our experiment shows how cultural dynamics can be explained in terms of competing evolutionary forces.",
