Playing Gospel music can be as simple as a 1-4-5 progression, or as complicated as you want it to be with the verse, chorus, verse, bridge, vamps, and so on, I enjoy playing it and I can tell you that a lot of the style comes from the blues (old style) and (the shout) is really a kind of rock and roll groove. (if you know what I mean). Most of the stuff I have played is complicated imo, from the standpoint of making sure everyone is on the same page with the many changes that can happen in just one song, like the breaks, vamps, etc... you can spend hours on learning one song that will only last a few moments, I guess you could say that about any music though. I really like when the music stops and the spirit of God has touched the people through the music that the music has to come back in because the people will not sit down because they want to praise God more. Check out some of Fred Hammonds music, or Mississippi Mass choir, (they have a bass player name Sam Scott) who..excuse my english "aint no joke"
Much peace to all! GOD BLESS!
