I'm new to drumming. I've looked at a lot of videos about stick gripping, including American Grip, German Grip, Traditional Grip, etc. Nothing I've come across has mentioned holding the sticks with only two fingers.
I find that if I hold the stick with just the thumb and 1st finger I have superior rebound, with a little help from my palm. When holding the sticks "correctly", the other three fingers just get in the way, stifling the bounce.
Can I get away with a 2-finger grip?
