This book has been written to teach Joel Rothman's tightly structured "Rhythmic Modulation" approach to practice. This approach has been shown to afford much greater control over the execution of rudiments.
The book is divided into two separate and distinct sections. Part One, "A New Look At Old Rudiments", presents a unique approach to practicing and developing traditional rudiments along with variations. Part Two, "Extended Rudiments", brings a totally different concept to what is usually thought of as a rudiment. An in-depth explanation of Part Two is given on page 34.
