Which guitar book?
Hi,
it really depends on what genre you are looking at,
if classical: i recommend
Hal Leonard Classical method for guitar, pretty up to date and the exercises/lessons are concise and easy. however i think taking lessons is always the best for classical if not picking up bad habits will be costly to undo
contemporary
to be honest, i think there is not one book which is good at all in the market for beginners. they focus too much on the wrong things like learning to read notes when chords should be more important/fun and scales. so in my opinion i think its better to take lessons or go to justin sandercoe (wwww.justinguitar.com i think?). you will know what i mean after a while by wrong focus because in my experience you will waste your money if you buy a book that doesnt cater to what you want. furthermore it goes back to learning bad habits again as theres no one to point out your mistakes.
yes it might cost a 2 or 3 times more but you can just opt and take 4 lessons then go off on your own.
