Hey,
me and a friend are trying to learn goodbye prokpie hat (Charles Mingus, duh!) for a concours. But as I started analyzing it, the first chord already made me say ***. We're doing the version in Fm, but the first chord is an F7... Where does that come from? Is Charles using special scales, or hasn't it got anything to do with music theory, but he put the F7 in it because he thought it would sound better?
Please help.
