Paradiddle Flow (2009) is a simple warm-up that emphasizes 16th-note timing consistency within different stickings (puh-duh-duh, paradiddle, paradiddle-diddle, slurred six-stroke roll). Practice at a single height (i.e. all taps) will build comfort with the different stickings. Practice at different accent heights will build comfort with the downstrokes involved.
The bass drum part is such that all the written notes could be played as a single unison part.
