So. In about two weeks I'm going to be stuck without access to a guitar for about 9 months (though I'll have internet access). Instead of crying and moaning about it, I might as well do something I should have done years ago: learn some proper theory. If you had about 30 minutes a day and no access to a guitar, how would you go about teaching yourself music theory so you can emerge a better guitar player 9 months later? Do I just straight up memorize the fretboard and then systematically memorize all the scale shapes and intervals needed for all the chords or what?
