Feeling Cross Section D is a compilation of the 16th note patterns from sections A, B, and C. This is a little more difficult (but very fun!), so take it one measure and one line at a time until you get comfortable with it.
The first line is right hand lead, with the patterns from Section A and B.
The second line is left hand lead, finishing the pattern from Section B and going into the larger crosses from Section C.
The last line can be pretty fun once you get used to it, moving around with a para-para-paradiddle pattern.
Now try the whole section. When the pattern is in your hands, turn on the metronome to 80 bpm (or slower!) and begin playing reps in front of a mirror.
As you play, shift your focus every few reps between the following:
-Play on one drum and around, making sure wrist rotation feels the same for both
-Keep crossing hand low -Stay perfectly in time with the metronome
-Keep heights consistent -Rotate through 3”, 6”, 9”, and 12” heights
-Tacet (non-playing) hand is still -Watch playing positions
As you get comfortable and are achieving the goals above, slowly increase the metronome by intervals of 8-10 bpm. Spend at least 30-45 minutes playing continuous reps.
Here are some of my reps at a few different tempos and heights. As you watch, critique my playing (no one is perfect!). Make note of anything you think I could do better. Keep these things in mind as you watch yourself in your mirror.
