21 Anything which has length or pitch.
23 In Lily, everything that can be thought to have a length and a pitch
24 (which has a duration which can be transposed) is considered "music",
26 Music is hierarchical:
31 class Music:public Input {
34 /** The kind of iterator needed to walk this music. This doesn't
35 make sense for simple (ie non-list) music, but it does no harm
36 here. Yes, it did harm Music_sequence: you can forget to copy it.
