There's only one problem with this arrangement; it had 7 flats. I know that it's in Ab Minor, which synonymous with G# Minor, which has only 5 flats. I notice that certain notes contain double flats, which mean that you go down a half step. It's not that I'm ignorant about key signatures, I'm and expert on it, [but I happen to be to time signatures, but that's a whole 'nother story...] but what about those who don't know as much about them? Someone even said that 'Papa' was in Eb Dorian, which isn't so; it's actually in Eb Minor, b/c that key has 6 flats.
