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