Alright, I have a brief background in theory, but am greatly looking to expand my knowledge as far as chords and scales go. Anyways, to do this I am looking at two books, but can not decide on which one to buy. Unfortunately I only have enough for one, so perhaps I can get your opinions on what book I should get for my purposes and why. Also, I do play guitar.
