rubato-composer

Rubato Composer provides a denotator-based framework for representing musical structures. Use denotators to encode notes, chords, and scores, with morphism operations enabling transformations like transpositions across your musical data in both Scheme and Java environments.

Yes. Rubato Composer bridges Mazzola's mathematical music theory directly into programmable workflows by integrating denotators, Forms, and morphisms. This enables scalable, theory-driven composition and analysis in code.

Clone the repository and run the build with ant. You'll need a Java core with Form and Denotator families, a Scheme interpreter, and bridging code to connect to ACSet schemas. The Scheme REPL or GUI launches immediately after setup.

Yes. Rubato Composer operates across both Scheme and Java. Scheme handles interpretation and primitives through SDenotator and SForm, while Java provides the core Form, Denotator, and Morphism infrastructure for music-topos operations.

Rubato Composer includes Form ↔ ACSet schema and Denotator ↔ ACSet instance integrations. Use these mappings to bridge your musical denotators into ACSet instances, enabling structured representation and manipulation of music-topos concepts.

Morphism operations in Rubato Composer include transpositions and other transformations across musical structures. These operate on denotators to systematically modify notes, chords, and scores while preserving structural relationships.
