In many respects, this book picks up where the original Master Studies left off. Some of the material shown here is more difficult than that found in the first book. Like Master Studies, it's a workbook of material to use indeveloping the hands. It is not a drumset or coordination book, although several of the exercises can be played on the drumset. This book can be used by the classical, jazz, rock, or even rudimental drummer, although it does notfocus on the rudiments as such. The exercises in this book should be practiced with a metronome. It will help you to play more rhythmically accurate by teaching you to space the notes correctly. Some of the exercises are verychallenging to play and require slow, sensible, and accurate practice. Please be patient. The results will be more than satisfying. -Joe Morello
