Descant
I don't know if their guitar is just longer than mine, or if they just tuned
up the 1st string, but I don't the exact fingerings. Maybe just bend it to
get it higher? Regardless, it's a tritone (augmented 4th/diminished 5th), so
wherever you choose to move it it's seven frets (three whole steps) apart.

Verse is just: 
rhythm on the sixteenth notes

|---10-12-12-12-12-12-12-12-12-12-12-12-12-12-12-12-------------------|

Then at the end of the verse,

|---------------------------------------------------------------------|
|---------------------------------------------------------------------|
|---------------------------------------------------------------------|
|----1-1-1-3-4-4-4-4--------------------------------------------------|
|----1-1-1-3-4-4-4-4--------------------------------------------------|
|----1-1-1-3-4-4-4-4--------------------------------------------------|

That's the basic jist of the song. After that, it fades into this piano bit
that I won't bother with here, and returns to the central riff. Which 
admittedly, just feels good in the base of my spine when I play it.
