Another flam accent/flam drag-oriented snare drum workout, which is a good companion to this one in 6/8 and this one in 2/4— this will be a little difficult if you haven’t mastered those first, actually.
Sticking is alternating, plus the drags and flams, obviously. Do play them starting with either hand. Observe the dynamics carefully— there are some unaccented flams which you’ll need to be careful with; on the accented drags in ex. 17-18, accent the first note of the double only. As with all flam studies, the grace notes need to be very small— around 1″.
