Yeah, I never figured out how to teach myself Papa. I play by ear and I get confused. Maybe someday, but I don't play that much anymore.
A lot of people keep saying the end of Swindler. I probably play it a lot easier and different than V does, but it sounds the same and I should write down how I play it because how I do it is not that hard. Kinda fast on the top hand but not impossible by any means. Ok I pretty much play the whole thing with the bottom hand just octaves and the top hand the melody bc it's easier that way. I know V does the whole top hand/bottom hand identical thing... but it sounds almost the same this way.
so... the end begins ordinarily, like the chorus, until the part that goes
F# - F# (or Gb, idk music notation...bottom hand chord, repeated between each top hand succession)
E,G (top hand)
G,A (top hand)
G, B (top hand)
G, G^+E, D, Db, B (top hand)
so that part begins at the middle C area, and after two times I just move my top hand up one octave
It's really easy!
