Modelling Musical Structures with Learn- and Rule-based Approaches
Dominik Hörnel, Karin Höthker, Joachim Langnickel

The research project "Information Structures in Music" applies methods used in computer science to analyze and model musical structures. One research interest concentrates on rule-based techniques (e.g. formal grammars), another uses learn-based approaches, especially artificial neural networks and genetic algorithms. For both approaches we present a system solving the musical task of  chorale harmonization. The resulting music pieces are judged by experts to be of similar quality as those invented by an improvising organist.
