This is the next step from Nine Stroke Lesson 1, where we learned to count a repeating nine-count while accenting the three and seven. I nthis lesson, we’re going to make the exercise to repeat on the right hand by placing a double stroke at the end, on the eighth and ninth quarter notes:

Loop Exercise – R L R L R L R L L
The goal is to be able to play this pattern while keeping a quarter-note count on the pedal hat (the same count as the metronome)
A useful update to this lesson
