I am not totally sure that the Transpose and Stem are valid on both the Clef and the Voice definitions - the abc standard doesn't seem too clear and some of the examples appear to contain extra clauses which are not in the definition text.

Also, I don't imagine they are needed in BOTH places, but it is easier and safer to code that than try and work out if already used.

Does anyone want the rest of this in abc? (another 16 bars). I haven't programmed it yet, but could if there was a demand.
