Computational Counterpoint Worlds ― Mathematical Theory, Software, and Experiments

The mathematical theory of counterpoint was originally aimed at simulating the composition rules described in Johann Joseph Fux’s Gradus ad Parnassum. It soon became apparent that the algebraic apparatus used in this model could also serve to define entirely new systems of rules for composition, generated by new choices of consonances and dissonances, which in turn lead to new restrictions governing the succession of intervals.

This is the first book bringing together recent developments and perspectives on mathematical counterpoint theory in detail. The authors include recent theoretical results on counterpoint worlds, the extension of counterpoint to microtonal pitch systems, the singular homology of counterpoint models, and the software implementation of contrapuntal models.

The book is suitable for graduates and researchers. A good command of algebra is a prerequisite for understanding the construction of the model.

Prof. Dr. Octavio Alberto Agustin Aquino received his Ph.D. in Mathematics from the Universidad Nacional Autonoma de Mexico in 2011. He is a lecturer in Universidad de la Canada, Mexico.

Dr. Julien Junod received his Ph.D. in Mathematics from the University of Zurich in 2010. He has worked as a statistician at the Institut Universitaire de Medecine Sociale et Preventive (IUMSP) of the Universite de Lausanne since 2002. He participated in the development of counterpoint plug-ins for the Rubato platform and a website about scales used at the IRCAM.

Prof. Dr. Guerino Mazzola earned his Ph.D. in Mathematics from Zurich University. He wrote the groundbreaking book The Topos of Music in 2002 — its formal language and models are used by leading researchers in Europe, India, Japan, and North America and have become a foundation of music software design. Prof. Mazzola has an appointment as professor in the School of Music at the College of Liberal Arts, University of Minnesota.
