This book will take you from beginner to solid rhythm player. It is a true musical trip into rhythm guitar and much more useful than a bunch of chord diagrams. Some chord theory is covered, and the chords are related to scales and positions. Short practice examples stress "basic moves" instead of full tunes, which is the best way to learn. If you can get through this book, you will fit in as a rhythm player in just about any style. I give 4 instead of 5 stars because there is no CD included - you do need to be able to read a bit to get the strumming patterns. This book is an excellent companion to "Chord-Tone Soloing", another great book from MI.
