If you’re serious about classical or fingerstyle guitar (or any other style, for that matter), you stand to gain a lot from reading
The Natural Classical Guitar. Ryan brilliantly combines a lifetime of guitar experience with his understanding of Transcendental Mediation and Daoist philosophy, creating a masterpiece of guitar pedagogy.
I wouldn’t recommend this one to a total beginner, but anyone else can use this book to push themselves to the next level. Ryan covers everything from effective practice to proper technique to performance preparation. If you’re like me, you’ll treasure it and return to it often. You can find this valuable book
