One main issue in the field of algorithmic composition is the relationship between the algorithm and the final musical structure. This article investigates that relationship further and presents a method of algorithmic thinking in which the musical form is the starting point. Kimon, an object-oriented programming environment for computer-aided composition in which one creates abstractions of musical form, will be introduced. The aim is to take algorithmic composition closer to the musical output in order to work systematically with form and dramaturgy. An electroacoustic piece that has been conceived and generated in its entirety by the system will also be presented.
