I dont mean to sound mean, but if you don't have the time / patience to teach him, why are trying to teach him? I think you would be causing more harm than good.
Take a poll. Ask the drummers of the room how many could play the basic 4/4 beat CONSISTENTLY the very FIRST time they sat behind the kit.
I for one couldn't.
I couldn't play a scale on a trumpet the FIRST time I picked it up.
That's why God gives us teachers.
Did you know your ABC's before you learned how to talk? Nope. A teacher taught you that.
If he has the passion and or the desire to learn the drums, and if someone is willing to teach him, He will grow.
Very interesting stuff you had to say ER. But for starters I mentioned that he would need a true teacher. I'm not a TRUE teacher. Everybody is not called to teach. Just like everybody who can sing, and sing very well, cant show others thier skills. This is why so many gospel groups fall apart because people think just because they have the ability to sing well, they can start thier own group. But thats a whole different story.
When I asked did he have the coordination and the basics down packed beforehand, he told me "yes". Well he obviously lied to me. There are drummers who are gifted enough to teach from the clean slate, and I am just not one of them.
When I was 5, I had drum lessons. And I don't know how that man put up with me because I didn't want to play counts, I want to do the rolls and stuff, and I was giving him a hard time. But because he had that "teacher mentality" in him, he put up with me, and got me started on the right path.
So its not that I don't want to impart something into somebody's life, its just that I don't have that ability to successfully impart meaningful lessons in to him.
