Seeing as Cave In tabs are rather thin on the ground at the moment, I've decided to make my own contribution
(Basically the end lick and the chords that follow it, that's all I can pick up by ear). Perhaps
someone can use this to aid their own tab of this song (if there are any). Anyway, here we go.

Cave In- 'Requiem', off the album Jupiter. (Tabbed by Ashley Webster)

In Standard, I think.

End Descending Lick:

e--12-12-12-11-11-11-9-9-7-7-7-5-5-5-4-4-2-2-2-0-0-0------------------
B----------------------------------------------------4-4-2-2-2-0-0-0--
G--------------------------------------------------------------------1
D---------------------------------------------------------------------
A---------------------------------------------------------------------
E---------------------------------------------------------------------

e---------------------------------------------------------------------
B---------------------------------------------------------------------
G--------6----------------------- 7--7--7/9-x-x-7---------------------
D--------6------------7-----------7--7--7/9-x-x-7---------------------
A--------4------------7-----------5--5--5/7-x-x-5---------------------
E---------------------5-----------------------------------------------

Let both of the initial chords ring out.

Repeat the lick again, then pick around the earlier chords.

For the third and final lick, do this twice quickly then
play the full lick again with the Db powerchord at the end.

e-12-12-12-11-11-11-9-9-7-7-7-5b6b5

Hopefully that wasn't too bad- enjoy!
