ISBN 9781609743628. This book is the perfect aid to help beginning to advanced drummers learn four-way coordination, or limb independence. Chapter One teaches students many eighth note drum set patterns, each one building on the one before. Chapter Two adds sixteenth note bass drum patterns to the eighth note hand patterns learned in Chapter One. The patterns are further reinforced by having the student play them in four-bar phrases. The student should not simply play the pattern written on the page, but should make it groove and come alive with emotion!
