Spend some time with each line on the snare drum until you're comfortable with the pattern. Then start moving it around the kit. Loop each line multiple times before moving on. I try to run each one for 10 minutes straight with absolutely no variation. It can be very tempting to deviate from the pattern or rhythm and add flams or rolls, but strictly limit yourself to only the one pattern and move it around the kit. You'll be amazed at the combinations you'll come up that you've never thought of before.
I've also found this exercise quite beneficial to the strength of my ears. We've all heard that you can only play as fast as you can hear. I used to struggle with my ears shifting the time by a 16th note or so when soloing at very fast tempos. Take, for example, the second page. Occasionally, when playing a pattern similar to this with accents moving around the drums, if a very strong note, say, an accent on the snare drum, fell on the "e" or "a" of a beat, my ears would shift that note to a downbeat. By working these exercises one line at a time, starting at extremely slow tempos and working my way up I noticed that my ears were getting much faster. In a sense, I was no longer guessing at what I played, or just letting my limbs fall where they may. Rather, I began to feel that I knew exactly where my sticks were going and when. Every note began to have a definite purpose, which, in my mind is the mark of a truly mature drummer.
After you're comfortable with all of these patterns start to mix and match them. At first stay within the same rhythm, but move from one accent pattern to another. Then begin mixing the triplet and 16th note patterns.
In a coming post I'll have a Part II with double stroke combinations.
