Sabbath Bloody Sabbath is the opening song of the self titled album released by Black Sabbath in 1973. It's a perfect example of how Tony blends open chords and single note palm muting to create a "dual instrument" effect that sounds like there's a bass and palm muted guitar to fill out the rest of the space. He does something unique that he doesn't do very often, playing 4 and 5 string chords in place of the power chords he typically plays. In this case, he has an acoustic approach, using chord strumming that is atypical to his normal playing, exemplifying his versatility. The solo uses double stops which is also atypical because he usually exclusively uses pentatonic shapes and positions. There is a repeated phrase that revolves around double stops and long quarter note triplets that further shows off his versatility and will give you a lot to practice.
