Maybe it's part of an A Chord? Who knows, you can't really hear it anyway. Guitar 2, however, gets these parts: /=slide down =slide up Riff 1 ()= only play 2nd time ()= alternative notes Repeat Riff 2 x2 Then just change the rhythm and play for another 2 bars Play the start of Riff 3 again, then go back into the notes from Riff 2 By this point the song has reached its glorious climax, and you should be 'feeling it' so much that it doesn't really matter what notes you play, everyone will (guitaretab.com)
