I've noticed that the level pictures here are rudiments, which is pretty cool if you ask me..
So, I have a question for all you drumset players out there...
How many of the rudiments can you play by heart and comfortably? Obviously drum corps people will be better at this but this is for the set players...
Sadly, I can't play more than half of them.. never felt the need really..
