Oops, I forgot my first-year theory.  In this case, he'd need to
write a scheme function.  Actually, it wouldn't be hard at all...
this is a perfect intro-level scheme tweak.

I leave it as an exercise for the reader.  Neil, Trevor, Valentin:
please don't give the answer.  :)

Then omit it.

melody = {a b c d e f g}

{ \melody \\ { \transpose c' g \melody }}
