Fomus

A part object represents a written part in the score. they are analogous to tracks in a midi sequencer or staves in any notation program, though a part may actually represent more than one staff for instruments that require it. part objects are containers for note, rest and mark objects (and optionally timesig and keysig object if they only apply to that particular part). each part object also specifies an instr object which contains specific information on how to notate a particular instrument.

part objects are passed to fomus by including them in the parts list.
