Notes:  During the riff, harmonics are picked at random and at various places.
During the chorus, a second guitar plays a heavily palm-muted A chord 
        (-5-7-7-x-x-x-) while the bass plays an A pedal tone.  When the riff is 
        noted without a number, the guitars are playing various endings, all of 
        which follow the basic figures transcribed above.
