Music21: A Toolkit for Computer-Aided Musicology and Symbolic Music Data
Michael Scott Cuthbert and Christopher Ariza
ABSTRACT – Music21 is an object-oriented toolkit for analyzing, searching, and transforming music in symbolic (score- based) forms. The modular approach of the project allows musicians and researchers to write simple scripts rapidly and reuse them in other projects. The toolkit aims to pro- vide powerful software tools integrated with sophisticated musical knowledge to both musicians with little pro- gramming experience (especially musicologists) and to programmers with only modest music theory skills.
Music21 looks to be a pretty neat toolkit for analyzing and manipulating symbolic music. It’s like Echo Nest Remix for MIDI. The blog has lots more info: music21 blog. You can get the toolkit here: music21
