My mother played piano and Hammond C3 at church for many years. I can remember going with her when she went to practice and she would let me "play" it. That thing was huge to me; it even SMELLED powerful. Had to learn the startup procedure so I could help my mom. She let me think she couldn't remember how to start it up.
I pretty quickly could pick out simple melodies, like Jesus Loves Me, or In The Garden,and she couldn't understand how a little kid could do that without seeing music notes! She never figured it out. She could play absolutely any music you put in front of her, but literally could not play Happy Birthday without it. She was still playing for church into her 80's.
She bought a piano and later an organ for our house, so it was always there if I wanted to play on it. I tried piano lessons but quit after a few months. Wanted to do it MY WAY. After stints with trumpet, drums and guitar, her plan finally worked and I started playing organ.
Now if I'd grown up in a church where they did that type of Gospel music, I'd probably be the music director today!
We had plenty of churches, but zero black people in our little town. Had lots of Native American friends, but then I've got a lot of Osage in me as well. I remember some of them doing old songs from their ancestors with tom-toms during celebrations. A lot of soul there, but no keyboards.
Seems the old man has rambled way off topic again. I'm going to get my new PA4X out of the bag now and try to play some of those B3 licks.
