I'm trying not to complain too much about this game, I love it. It's just that the guitar chart is completely different than I expected, and no it has nothing to do with the piano.
Listen to the first "life" in "all my life". Now, what it sounds like to me is little guitar triplets, for lack of a better word. Like, quick R-Y-B hammer on triplets. Could someone clarify whether that is a guitar?
