i think i understand most of it, but my only trouble area is with finding chords and also scales. like, where do all scales begin? i know where a minor, c major and c minor start, but others i dont know (i dont think theyve been taught so far). Also, i dont understand how you can go back on scales and use notes on the upper strings as chris does in his videos. apart from that, everything is nice and understandable, so what i intend to do is go back and watch some of the more difficult videos a few more times. best of luck !
