Impro-Visor

Impro-Visor® is a music notation tool for producing monophonic lead sheets, specifically intended to help the improviser. Chord symbols are used to generate backing tracks automatically. Improvisation advice exists in the form of note coloration, database of licks, and automatic lick generation from grammars. Grammars can be learned automatically from transcriptions. Styles can be edited and created by the user. Other features include generation of roadmaps for understanding keys and idiomatic chord progressions, chord voicing keyboard, MIDI and MusicXML export. See http://www.cs.hmc.edu/~keller/jazz/improvisor for general information, including tutorials. Support and additional resources are through the user group https://groups.yahoo.com/neo/groups/impro-visor/info.
