Matt's approach is innovative, refreshing and focussed on guitar players. I've not worked through the whole book yet but I have looked through it - I believe it will help me and others who wish to improve their knowledge and playing of jazz guitar; actually I think it must work with many guitar styles. It fits in very well with the other eBooks I have purchased from Matt and Dirk's Jazz Guitar site. I am also pleased to make such a purchase because of the amount of free teaching and encouragement I receive from being a member of JazzGuitar Online (membership is free). If one is serious about moving forward with the study of jazz guitar this book should prove to be a significant help.
There are a ton of information in this book presented in the most simplistic fashion! The important one for me is the lessons on key signatures. Recognizing these and associating those to find them in fretboard. And then goes on introducing the arpeggios for each key signature of the common jazz chords and how to play them. And there is a lot more than what I have described as I haven't read the rest yet. This will take me weeks if not months to master and I am looking forward to it. Overall it the most comprehensive materials covered in this book and one of the most important books in my collection and worth every penny! Absolutely great work! Truly appreciate this book in every sense!!! Don't hesitate to buy it.
