This isn't 100% accurate, but it's well enough. This is the main riff, minus the pinch
at the end; So it's essentially the rythm guitar. The bass during the verses is the same
played on the 4E string aswell. Also, it's in 4/4 signature, listen to the song as you 
it helps. Have fun, and feel free to email me if you have a better version, or if
know the rest of the chorus. blacksabbath5678@aim.com I speak english, spreche deutsch,
