Below is a great exercise created by our teacher Madi for any of the beginner drummers out there. It focuses on improving accents in a single stroke roll and developing independence between your right and left hand.
Key points to focus on while practicing this exercise:
Maintain even/equal stick height and consistent sounding strokes between both hands
Maintain good technique (stick grip, rebound and control)
Tip: Try playing your non-accented notes a little quieter, this will help to make sure your accents sound more prominent while practicing.
