Re: Nashville notation as chord symbols

[Amelie Zapf]

Dear Klaus, Stan,

the following code moves the transposition into the
#note-name->international-markup routine, thereby eliminating MIDI
playback problems. Downside: we still cannot pass the tonic to the
routine directly, but have to state it there anew.

And, of course, the rhythmic elements of Nashville notation aren't
implemented yet.

Greetings,

Amy
