Ever heard of the “Flying Fingers Technique”? It’s another way to hit the drums that involves using only your finger power on the sticks. It’s more common among the speed metal genre, but has a lot of use outside of metal. The technique is utilized typically for fast tempo single strokes. The wrist/arm energy you’d normally use for something like this can be conserved by using this fingers only method (not to say it takes no energy, but uses a lot less).
Why is this useful? Endurance. Plain and simple. Whether you’re performing a live show, recording at a studio, or just practicing by yourself, stamina is crucial to playing music. But don’t get me wrong, this doesn’t mean you get rid of all other arm/wrist techniques. This is simply a useful tool to have in certain situations.
I’m hoping to perfect this technique soon and then teach it to my students. I have a lot of work to do with it still, but that’s what practicing is for!
