Why does the drummer have a rack of Spock toms

Are you referring to the six little heads off to the top of the kit, looking at it to the left side?

Yeah

And don't they have a different sound than the bigger drums?

Yeah, if you ever listen to marching tenor drums, the really small and high pitched one is a spock

That's very interesting. Have you ever played one?

No, but I've seen people play them, I'm just a part of drumline and front ensemble

I'm sure you'll expand your playing knowledge in time. I'm also sure you'll do great!

Thank you!

You're very welcome! Keep drumming away!

Oh I'm not a drummer I just recognized that
I'm actually a pianist

That's actually very good, that you know how the other instruments and their sounds work. That will help you a lot if you want to compose music, because you will have an idea of the sound you're looking for to go with what you are playing. You'll do great things I'm sure.
