Re: List of things you have to master to be a good drummer
First off, you have to define what your goal is.
No is a master of everything. Some drummers can play a little of everything, some are great at certain styles but never touch other styles. Some people want to be a working drummer doing whatever gigs they can find, some just want to join a band and never play casuals.
What interests you? Jazz? Country? Extreme metal? Polkas?
Of course, many of us start out thinking we want to do it all, but reality tends to get in the way of that.
Anyhow, once you have a better grasp of where you are trying to go, it's easier to figure out the path to get there.
