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. This release adds music theoretical concepts. A generalized version of Schoenberg's guidelines on writing good tonal chord progressions have been implemented as constraints. Strasheela now facilitates composition in 31-tone equal temperament (31 ET). For example, various 31 ET chords and scales are provided, and output to Lilypond, as well as Csound is supported. 31 ET MIDI output can be defined by the user, depending on your MIDI setup. Other additions and bugfixes have been made to the system as well.
