Abstract:

We present in this paper our recent developments dealing with computer-assisted music analysis. Our focus is in a new syntax that extends the patternmatching part of our constraint-based system called PWConstraints. PWConstraints can be used both to generate musical material or to analyze existing scores. The syntax allows to refer to more high-level entities in a score than before, resulting in compact analysis rules that use only a minimal set of primitives. Rules can return expression objects which can be used to visualize analytical information directly in a score. The compiler can be extended to support new score accessor keywords by special compiler methods. The new syntax and visualization of analysis data is explained and demonstrated with the help of several analysis examples.
