Functional Harmonic Analysis and Computational Musicology in Rameau
TLDR
The infrastructure for computational musicology and functional harmonic analysis in Rameau is presented, a framework for experimentation with musicological ideas in software, and can be easily extended to support many other features.
Contour Algorithms Review
TLDR
This paper presents some problems of two Music Contour Relations Theory operations algorithms: the Refinement of Contour Reduction Algorithm and the Equivalence Contour Class Prime Form algorithm, and proposes two alternative algorithms to solve these problems.
