On the Stylistic Evolution of a Society of Virtual Melody Composers

. In the field of computational creativity, the area of automatic
music generation deals with techniques that are able to automatically
compose human-enjoyable music. Although investigations in the area
started recently, numerous techniques based on artificial intelligence have
been proposed. Some of them produce pleasant results, but none is able
to effectively evolve the style of the musical pieces generated.
In this paper, we fill this gap by proposing an evolutionary memetic system
that composes melodies, exploiting a society of virtual composers.
An extensive validation, performed by using both quantitative and qualitative
analyses, confirms that the system is able to evolve its compositional
style over time
