Copyright with the author © Copyright 2003Since Pythagoras, music has been a vehicle for the physical realisation of abstract scientific principles. Algorithmic composition is as old as music composition (Jacob 1996), and a more recent development in this field has involved the use of composition methods based on Artificial Life This paper presents a discussion on existing composition systems, exploring both the problems faced by system designers, and how differences in the composer’s philosophy and approach ultimately have an effect on the possibility of creating innovative music. The author’s own system will also be discussed in detail with a focus on the composition of two works; ælife for Orchestra, and Fight or Flight (the prisoner’s dilemma) for percussion ensemble. The two works presented show how the system is modified to answer specific problems which arise when composing different works.enArtificial Life and MusicAlgorithmic CompositionExperimental MusicCellular AutomataThe Prisoner’s DilemmaEvolutionary AlgorithmsConference paper00200927252009102015005337481Harrald, L.
