Hi Johnny, I got the sheet music transcribed to the proper key for this song of Michael Bolton’s version of “When a Man loves a Woman.” Playing it now, the difference is like night and day. Listening to the backtrack, it seems like the Key of this backtrack changes towards the middle of the song for a few measures and then goes back to the original key towards the end of the song. It sounds like it goes up a pitch or so from the middle of the song towards the end of it. There’s nothing in the Key Signature that shows that anything changes, but sure sounds like something happens when listening to it. Should make a beautiful song on the Saxophone.
