Just yesterday I started learning Pretty Baby and thought it would be neat to bring the song down a half-step. I also found that the song was easier to play [and sing to] when I transposed it b/c it has 4 flats; moreover, I've never played anything in Ab before. There's a song [by a another artist] close to my heart that's in Ab, so I was inspired and got the brilliant idea to transpose Pretty Baby down to that key. I never play V's songs exactly like her b/c as an artist myself, so it's fun to put my own interpretation on her music w/o taking anything from it. It's a good thing that Maag transcribed the song the way she did b/c there's much room for inprovisation, although I'm a little disappointed that she didn't throw in the key change that comes near the end. It's okay, b/c there's room to make the song your own. When I went to musicnotes.com a while back I found that you could transpose the song in different keys.
