PyChoReLib 0.0.5

PyChoReLib is a Python library which transforms lists of notenames to a chordname. The system uses built-in music theory knowledge to make it easy and quick to add support for new chord types
PyChoReLib, in the current form, accepts a list of note names, and transforms those to a chord.
e.g. [a, c#, e, g] => A7
Inversions are indicated using a slash and the root note.
e.g. [e, g, a, c#] => A7 / E
Main features:
- PyChoReLib can already name and recognize hundreds of chords
- New chords can be taught to the system "by example" e.g. teach the system that [c,e,g] is called C, and using its built-in music knowledge it immediately knows how to recognize and label all major chords in all inversions or (more generally) permutations.
- Once chord recognition definitions have been taught to the system,
- they can be saved to file, allowing for quick initialization of the recognizer
Planned features (planned != promised)
- Extending the chord recognition database with new chord patterns
- Improving the recognition speed for chords with many notes
- Maybe small GUI to allow interactive chord labeling ? Midi keyboard import ?
- Add heuristic rules to recognize more chords, while requiring less teaching
- Add functionality to suggest a scale which can be used to improvise over a chord
Enhancements:
- Dramatic speed-ups in chord teaching and recognition, a new scale recognizer, support for distinguishing modes, a slightly more robust MIDI input demo, and refactoring to avoid code duplication and use Python new-style classes.
- The serialization to XML was removed as it was not useful and didnt work with new-style classes.
- Many bugfixes were made.
