To make the right stick pattern clearer, I’ve broken some notation rules below. The X noteheads represent the right stick strokes. You can see that they fall on all of the 8th notes, just like in the main beat. Notice that the right stick pattern plays: low, high, low, low, high, low, low, high.
Step 2
Step 2 builds upon step 1 by moving two of the left-stick strokes. The snare strokes on beats 2 and 4 (i.e. the backbeats) remain on the snare, but the other two snare strokes from the main beat are moved to the high tom. I’ve used more improper notation to show what the left stick does. The diamond noteheads represent the left stick, and the X noteheads represent the right stick. It can be helpful to first learn the hand part, adding in the bass drum later.
