music analysis and algorithmic composition
AthenaCL is a modular, object orientated, interactive command-line environment for music analysis and algorithmic composition. Scores are created in Csound as well as standard MIDI files. The software is open-source, cross-platform, and written in Python and XML.
Musical parts are deployed as textures, layered surface-defining objects containing linked parameter objects to control pitch, tempo, rhythm, amplitude, panning, and Csound synthesis and control parameters. The system includes an integrated library of Csound instruments. Parameter objects provide generators using stochastic, genetic, and various other algorithms. Textures can be combined, edited, cloned, and tuned with algorithmic temperament objects.
The analytic and algorithmic systems use path objects to organize and share pitch data. Based on post-tonal music theory, paths provide simultaneous representations of ordered content groups in set-class, pitch-class, and pitch space. Paths can be modeled with the Straus voice leading system and analyzed with numerous set-class similarity measures. As a reference utility for music theory, pitch groups can be searched, analyzed, and compared with a wide variety of tools.
