This my attempt to tab out Clarity from the Linkin Park Underground 12.

I feel as if their are octaves being played, this is what I think it is. Either
Standard/Drop D tuning or Drop D, half-step down.

-5(6)---6(7)--8(9)---------------------------------------------|
-x(x)---x(x)--x(x)---------------------------------------------|
-3(4)---4(5)--6(7)---------------------------------------------|

Note: Strum as much as you need to.
Note: The ones surrounded by parenthesis are the ones for drop D, half-step down.
