Interesting software which analyzes compositions and uses that information to generate new ones with capabilities of combining multiple compositional styles.
Kulitta addresses the task of musical composition in the Western classical sense, which is at the level of a paper score. Kulitta uses generative grammars to create abstract musical structure, which is then progressively refined using mathematical models of harmony called chord spaces. Finally, style-specific foreground algorithms turn those harmonies into a particular type of music, such as a classical chorale or a bossa nova. Kulitta is highly modular, and modules tallKulitta can also learn from existing music, deriving information about its abstract harmonic rules to help build a musical grammar that is representative of the style.
