For the left hand guitarist, introducing a major new feature for print books: sound! Now you can see the chord, then reach for your phone and hear the chord. Using any free QR code reader app (Android, iPhone, Blackberry, Windows) a web site opens automatically and you can listen to the chord as a strum, an arpeggio (each note played separately) and hear it as a piano chord and arpeggio. Of course, Flame Trees straightforward, easy-to-use diagrams make this a fantastic new book for beginners and intermediate players, for home, studio and rehearsal.
