Music Synthesis Based on Nonlinear Dynamics
(Proceedings pages 467–470)
Music composition from nonlinear dynamics has been a subject of
thorough research, producing interesting music tracks. Simple chaotic
maps or even more complex iterative schemes have been proposed,
taking advantage of the "structured spontaneity" of nonlinear
dynamics by directly transforming the mathematical objects to musical
entities. In this work we examine the music compositions produced
by two nonlinear systems in terms of complexity, expressed through
the Shannon Information Entropy of their Pitch Class Profiles. We
present a methodology to interpret the information obtained by
the iterative equations to several tonal and rhythmic attributes.
This methodology is implemented in real-time software. A Graphical
User Interface is provided that allows the user to adjust several
variables while listening to and observing the derived results.
