I can do the basic four changes for preaching chords...followed by a quick, simple run and back to the root. BUT I HEAR MUSICIANS DOING MUCH MORE AND I DON'T WANT TO BE LEFT OUT...especially since I play for a church now. Most of the posts I see have the basic 4 changes but I need some "in-between stuff". My preacher never leaves A-flat, B-flat, D-flat, and E-flat (THANK GOD)! SO, any help will be a great asset! Thanks.
