Oh no. It's lots more than that. There's performers an attractions, all the fun stuff, which I think includes the peanuts at least for sure. S'just not a carnival without good peanuts.
Well, if you can clap that's just fine it is, and I'd be we can make something off it just the same. As for me, bit of both really. Learned to play mostly by ear now, but I started out having to practice reading and writing music. Most times though I just listen to something a time or two and I can figure out how to turn it over to the violin.
