content: Excellent book. Does not assume any musical training, explains everything starting with the music notation. The exercises are truly gradual: each introduces only a few new hand positions, and future exercises reinforce hand positions introduced earlier. The early exercises are simple yet sound reasonably well not to be hopelessly boring, and one can hear when one plays them incorrectly. Great book for self-study. It was recommended to me independently by two very good classical guitar players; and my technique and sight-reading skills have improved notably since starting to use this book.
