This final exercise is one that began when I heard a student of mine play what she thought was a double stroke roll. She really enjoys playing this pattern, and even though it's not a double stroke roll, it is still useful in helping us with our double strokes.
This exercise works by isolating each hand but does so in a way that is different than the first exercise in this series. And because it works only just one "side" of the doubles, this exercise could've been the second one in the series, but I chose to put it at the end due to it's use of 16th note triplets. This rhythm can be tricky for beginning students to play and read too. Be sure to take it slow, and when you get to the triplets, you can say "evenly" or "trip-o-let" as you play the rhythm to help you with the timing.
As in our second exercise, the first measure has you play the "skeleton" of what you'll be playing in the second measure. Be sure to spend more time practicing your weak hand (for most of us that is our left hand), and though it will be frustrating, you'll find your technique WILL improve as you focus your attention there.
When playing the second measure, the two doubles followed by the one single note should sound like: "digga-duh digga-duh digga-duh digga-duh". Both doubles should sound clear and articulated.
