Watch the SECTION 2: Rhythm Studies online guitar lesson by Angus Clark from Hard Rock Survival Guide: Rhythm
I did a bunch of homework for this course to make sure that what I'm covering in "pan-decade", we're covering them all. At the end of the day, what we call hard rock is just as diverse as music itself, so here's a sampling of stuff that you can sink your teeth into. Have fun with it, I know I did! Every exercise is a relatively short, repeated form, which I play through once or twice. Then the form just repeats for you to play over and get into the groove with. There are only two or three sections in each exercise.
