>With drumming

Drumming, in a band context, is all about remembering certain drum patters, combinating them mentally so they fit the music as well as possible, and then playing them with perfect timing...

... all of this in real time, and as an endless while(song is not over) loop!!

>And who's gonna tell you if you got it right or wrong?

You don't want to make the bassist, the singer, the guitar player, and the keyboard player all get angry at you at the same time for making the group sound bad!
