Doh! Yes indeed. This is all part of an ongoing discussion about how stuff should be represented in the Music:: namespace, once I get around to writing Music::Chord and Music::Keysignature etc. I'd so far been going with ISO format for input/output, just because it looked nicer :)

Thinking just a little into the future though (I *must* get into the habit of doing that :) ), it'd make a lot more sense if eveything dealt with Music::Note objects - I then get to do all the cool functions like $note->transpose(), $note->enharmonic_equivalent('natural') and $note->is_jazz_accidental_and_not_a_mistake().

Thanks all - I knew that posting would save me days of re-coding :)
