@OmSigDAVID,
Quote:When I was 13, I used to play the radio.
That was my favorite musical instrument.
I got in plenty of practice.
I got to be pretty good at it.
I never took formal lessons for it; no grief.
I was able to turn to my favorite stations quickly.
I continued with it for thru out my teenage years.
I even played it in the car.

- Me too - and I liked the part about being able to play it in the car.
Quote:In time, I grew somewhat bored with it,
tho I listened to talk radio once in a while.
I've never gotten bored with it, and on a more serious note, I actually think that constant exposure to or listening to musicians who were better than me, inspired and spurred me on in terms of applying myself to my own lessons.
Maybe you could show Mo the video of Keith Moon (of the Who) playing the drums on 5:15 (from Quadrophenia). If I were wanting to play the drums, one look at that video would get me practicing.
On the other hand, if he doesn't practice or play the instrument, he's not gonna make progress and paying for him to go sit and play the same thing he played the week before week after week doesn't make sense.
I'd present it to him like this - 'You say you like to play, but I never see you play. If you like to play, and you want to get better, you need to show me that you like to play- and I'll be happy to keep paying for your lessons.'
If he's hit a rough patch and wants to quit - that doesn't have to mean forever. He's eight - that's when most kids START an instrument. As long as you keep the drum set, he can always go back to it- and the lessons will still be there. If he's a musical person, he won't be able to resist it. My daughter quit the violin, and now three years later, she's teaching herself to play the piano - and I'm amazed at how good she is...she's never had one lesson on the piano and she picking out the right and left hand of Fur Elise (just from having heard it). She's working on putting them together now. Three years makes a big difference in maturity and level of commitment to something.
