Elevateci Pitch: Automated Grammatical Evolution of Short Compositions

摘要

A system for automatic composition using grammatical evolution is presented. Music is created under the constraints of a generative grammar, and under the bias of an automatic fitness function and evolutionary selection. This combination of two methods is seen to be powerful and flexible. Human evaluation of automatically-evolved pieces shows that a more sophisticated grammar in combination with a naive fitness function gives better results than the reverse.
