Disappointing - Nothing new, nothing original . This is an example of one of those thousands of guitar books which discusses several subjects in a superficial way and never really nails anything down in a useful way. The author has not put forth a single original idea or even bothered to present the same old stuff in a new and different way. This book is not a guide to the fretboard, it is basic music theory for absolute beginners. If you want rock solid information about the guitar's fretboard skip this and do what everyone else does: get Fretboard Logic. The author has released several books under the same title with pretty much the same stuff in each one. This one is a Mel Bay retread
