that is based on a
musical score metaphor, and consists of a hierarchy of notes, phrases, parts and score. jMusic also has a sound synthesis architecture and "instruments" can be created from a chain of "audio objects" (similar to unit generators in other languages). A jMusic score can be rendered with jMusic instruments to an audio file.
Code Sample
Note n = new Note(C4, CROTCHET); // Middle C (quarter note)
Note n2 = new Note(G4, CROTCHET);
Phrase p = new Phrase();
p.addNote(n); // Add C
p.addNote(n2); // Add G#
