In this article, the author focuses on issues concerning musical composition practices in which emergent behavior is used to generate musical material, musical form or both. The author gives special attention to the potential of cellular automata and adaptive imitation games for music-making. The article begins by presenting two case-study systems, followed by an assessment of their role in the composition of a number of pieces. It then continues with a discussion in which the author suggests that adaptive imitation games may hold the key to fostering more effective links between evolutionary computation paradigms and creative musical processes.
