Joel Rothman Publications
The Holy Grail for Total Independence at the Drum Set

Ambidexterity is a rare gift—very few people are born with it, but Joel’s book puts you on the road to achieving ambidexterity even though it may not be inborn. The exercises are extremely easy to read—there’s only one staff line with notes above for the right hand, and notes below for the left hand.
Rhythmic notation includes just eighth and sixteenth notes, and what you do with your two hands is one of 11 different ways to apply the exercises between your four limbs.
Actually, you don’t even have to be a drummer to play this book—anyone who can read rhythm can do it. In a real sense it’s a game book, and fun to play.
