I am on Fundamentals 2 and working on the C Major and A and C minor scales. My question is how important is it to learn/memorize all the different patterns to each scale? I am trying to be patient and really focus on the basics (my goals are really to play some fairly basis guitar, but don't want limits either), but feel like I could spend a LONG time just on Fundamentals if I really commitment to all the scale patterns, chord changes etc?
