Q sent me sheet music for "La varsoviana," and I transcribed it to a MIDI which you can play here (click)
The pattern for the dance is here (click).
Trouble is, I can't quite figure how the song goes. If somebody wants to help, I can e-mail you the sheet music and maybe you can advise me if it's correct.

I think the pattern is AAB AAB - but all I've been able to get Noteworthy to do is the AAB part once. I think that's enough for you to get the idea of it.
