I agree with the fellow who said to angle the drums to facilitate rim shots.
It opens up a whole new library of dynamics and sound from your kit. My
sticks look like a beaver had a field day about mid shaft from all the rim
shots I play.
When I'm live, it's almost a given that I'm hitting the snare and rim on every
hit. I love the sound, crack and overtone.
The same angle also allows for more power to transfer from the stick,
especially on the toms. If you have too much angle, the stick tends to
skip off, and the sound is weak.
Think of a hammer, or a punch hitting a surface: the more square you are
to the target, the better the transfer of energy.
