I would say some sticks, a couple of practice pads and some lessons. If he sticks with it for a few months then you can think about getting a drum kit.
I was figuring lessons would be the way to go but was hoping it could be self taught easily. I have heard that piano lessons are required at some schools, that makes sense that the best drummer in my grade could play the piano too. ThanksHe’ll hate it, but taking piano lessons helps immensely with coordination. (Not sure if its changed but way back when I was in grade school, you had to take 2 years of piano before you could play percussion in school).
Get him a snare drum to learn the basic rudiments and stick handling. (Practice pad if you want to keep your sanity). Get him some basic lessons. Don’t just get him a drum set and toss him on it, it’ll be a waste of money.
