Hopefully you know the drill by now: first play the ostinato until it is comfortable and swinging without any snare drum at all; then learn the entire page; then drill the page with the tom moves. The accents written on the plain ostinato are for phrasing; play them lightly, or not at all, when playing the exercises. Notes in parentheses are optional; where they are present, learn the exercise both with and without those notes. If you experience any problems with the rest at the beginning of the pattern, you can play the snare drum lightly on 1 until you get the timing. You may also find it easier to start the exercise playing the ride cymbal on 1, and then playing the pattern as written on the repeats.
