Black Sabbath, the title track is named after both the band and their debut album "Black Sabbath" which was released in 1970. This one's interesting because it's very sparse and atmospheric. It incorporates a trill which is basically really fast slurring between two fingers on the same string which gave it a really dark feeling in the diff. Then the song breaks into a double time feel where you'll use a palm muted G Minor chord shape that revolves around the first position, as well as some open string positions that have a great drone-like effect. This song makes for a great chance to practice your musicality and timing.
