Guitar book to complement my guitar lessons?
I have recently started guitar lessons. I really love them, but I feel there is something missing. My teacher's approach is "every class, let's learn a new song" but I feel I need some theory, like how to build chords, what note I make if I pulse this or that string, or playing techniques, etc. That is why I thought I could complement my lessons with a "theory guitar book" where how to play the guitar is explained and with progression of exercises. Is there such a thing? Or my teacher's approach is the way to learn to play an instrument (It is the first time I ever attempt to learn to play a musical instrument). Any advice will be welcomed!!
