I just figured out a weak point I have. I've been trying to solo over Sweet Georgia Brown but couldn't get it right. I know the chords and I know how to solo over them. However, the chords go E7 for 4 measure, A7 for 4 measures, D7 for 4 measures, G6/9 for 3 measures and B7 for 1 measure. Basically I struggle with playing over chord progression a where it stays on 1 chord for that long. For example minor swing is 2 measure per chord so that's fine. Well, guess I got to practice that.
