Amuc is a light-weight tool for composing and playing music. 'Light-weight' in
the sense of not needing graphical or other toolkits. It is very fast and
offers useful features to help the inexperienced composer. Now it also
incorporates a pitch extractor, translating a wave file to notes. Listen to a
fast solo by John Coltrane on saxophone, followed by the extracted tune with
a simple accompaniment, and then with a synthetic bass gitar and sampled drums:
