Main intro rift, Trey changes it around sometimes, but it is generally like this:
e|-------------------------------------------------------------------------|
B|-----------9--------11--/12---11----9---9-------/12-11---9-----9---------|
G|-6-7-8-9------9-----------------------8---8-----------------7-----7------|
D|-------------------------------------------------------------------------|
A|-------------------------------------------------------------------------|
E|-------------------------------------------------------------------------|

e|-------------------------------------------------------------------------|
B|----------9--------------------------------------------------------------|
G|--6-7-8-9---6------------------------------------------------------------|
D|-------------------------------------------------------------------------|
A|-------------------------------------------------------------------------|
E|-------------------------------------------------------------------------|
Then where the 6 ends, that tranisitions into the six that starts the song, and the 
continues similarlly to that. The second time round, it is played like this
e|-------------------------------------------------------------------------|
B|-----------9--------11--/12---11----9---9-------/12-11---9-----9---------|
G|-6-7-8-9------9-----------------------8---8-----------------7-----7------|
D|-------------------------------------------------------------------------|
A|-------------------------------------------------------------------------|
E|-------------------------------------------------------------------------|

e|-------------------------------------------------------------------------|
B|---11--/12----11---------------------------------------------------------|
G|------------------6------------------------------------------------------|
D|-------------------------------------------------------------------------|
A|-------------------------------------------------------------------------|
E|-------------------------------------------------------------------------|
