Abstract

In this paper we propose an automatic music composition system for dodecaphonic music based on a genetic algorithm. Dodecaphonic music, introduced by A. Schoenberg, departs from the concept of tonality by considering all 12 notes equally important. Dodecaphonic compositions are constructed starting from a 12-note series, which is a sequence of all the 12 notes; the compositional process uses the starting 12-note series as a seed and builds the music creating new fragments of music obtained by transforming the seed series. The algorithm proposed in this paper automates the compositional process taking a seed series as input and automatically creating a dodecaphonic composition. We have implemented the algorithm and we have run several tests to study its behaviour.
