Okay, here's the scene:
We have a bass player, drummer, organist, lead guitar, and me on the piano. Someone stands up to testify and starts to sing a song that doesn't have a definite tempo. The bass player, drummer, and lead guitar obviously can't play with her, so, its up to me and the oranist to back her up. The organist was holdin' it down and doin' his thing, but, how do I add the harminization in with the piano? I mean, I've heard some crazy stuff done, but, how do you do it? It would be very helpful if you had a video or something like that of what to do on a piano that you could show me or tell me where to buy one.
Thanks, be blessed!
