There are a few things you need to do for fast (and smooth) single stroke rolls. A lot of younger players think that if you just blast the sticks down on to the playing surface as fast as you can. Wrong. That will sound like you barfed all over your drum. Gross. We definitely don’t want that.
The secret is this: 1) staying loose; 2) knowing when to switch your mechanics up (wrist vs. fingers, etc). and 3) keeping your check hand in time with whatever tempo you are playing at, whether just in your head or within an ensemble.
This exercise below will help you do all three things. Watch the video below for more explanation.
