For me, I want to learn theory and how to play by ear.
When you have a beginner like me striving to learn the theory, and to be able to hear and play by ear and at the same time get "THROWN" on the keyboard when it is time for service.
The congregation is struggling to sing the songs because most of them they don't know, and I have yet to see songboooks in some of the apostolic ministries, so they are lookin at you.
Then at practice I try to remind the leader that the team is learnin the song in the wrong key, and that we can use the piano to keep them in the right key,and that is not always allowed. And then you practice, practice, practice, and the songs you practice are not the ones that get sung, because the "spirit has shifted". It wears me out...and no this learning to be a musician is not paid, I don't I just want a pure worship/praise session.
