Abstract
NEUROGEN has been designed with a view to producing small
diatonic, western-type, four-part harmony compositions using the
knowledge extracted from a set of example musical fragments provided by
the user. The aim has been to produce a piece of coherent music that
resembles that typically found in traditional hymns. A set of neural
networks are used to capture the conceptual ideas that build `good'
music and this knowledge is then used to direct a search for the
ultimate composition. Genetic algorithms hold many member states
representing partial musical fragments. The neural networks cooperate to
produce a heuristic value that represents the worth of each of these
musical fragments. This value is then used to evolve better compositions
based on fragments with high fitness values. The use of Neural Networks
as an evaluation function has proved successful in the guidance of
genetic algorithms. This success is evident in the type of composition
produced by NEUROGEN
