Strasheela is a highly expressive constraint-based
music composition system. Users declaratively
state a music theory and the computer generates
music which complies with this theory. A theory is
formulated as a constraint satisfaction problem
(CSP) by a set of rules (constraints) applied to
a music representation in which some aspects are
expressed by variables (unknowns). Music
constraint programming is style-independent and is
well-suited for highly complex theories (e.g. a
fully-fledged theory of harmony). Results can be
output into various formats including MIDI,
Lilypond, and Csound.
