This is the intro riff that is played throughout the song, a very sexy riff if I might 
and very simple to boot.

Tuning: Standard

Distortion
e|-------------------------------------------------------------------------|
B|-----15^(16)---15--15-13-12-10---------12-15^(16)---15--15-13-10---------|
G|--------------------------------12-14------------------------------------|
D|-------------------------------------------------------------------------|
A|-------------------------------------------------------------------------|
E|-------------------------------------------------------------------------|

I think there might be a pull off somewhere in there, but I haven't figured it out yet.
