Can only be THANKFUL it's in my hands NOW...FINALLY!" (5stars) by Retired Redleg "Actually did throw out a myriad of books on the subject..this is my 'go to' resource! After 30 years playing I finally understand what's going on!!" (5stars) by `__´ "An absolutely genious way to learn chords, and not just chords, This method unlocks the pattern / chord-shape-stuck guitarist's thinking and allows one to construct chords, scales and arpeggios easily and in the most logical way possible. It helps one to understand why certain things sound how they do and helps to see how intervals, chord shapes and inversions are connected to each other. Honestly, this method is all you need to learn ANY chord or arpeggio there is. Most importantly, the method is FUN, rewarding and once the method is learnt the system starts feeding itself, so you'll never ever forget what you've learnt with the method, you'll only get deeper in seeing how the fretboard works. Sounds too good to be true, I know, but I learnt the guitar with the predecessor to this, the Only Complete method. Understanding chords, arpeggios and scales through the method has been the biggest "EUREKA"-experience for me in my 15 years as a professional musician. It made me realise that chords or scales aren't hard, they're completely logical and learning them is easy. This method unlocked the fretboard and the how I approach the guitar in general for me, I highly recommend this App to everyone, from beginner to pro player." (5stars) by Pro Music Man.
