the only chord in question is Gmaj13. It is actually Gmaj13no3no9. Not that that matters 
Here's what does matter to you:
 Gmaj13
---0---- | 
---1---- | 
---0---- | 
---0---- | 
---3---- | 
---2---- | 

basically, after playing a C chord, move your middle finger off the 2nd fret of the D 
and onto the 2nd fret of the E string. not wholly complex.

C      Gmaj13      C              Gmaj13
I will bury you in time when the sea begins to

C       Gmaj13             Em           G
slide into this hole where I am smiling on your shoulder

C        Gmaj13       C            Gmaj13
You have buried my be-liefs where all your sisters

C            Gmaj13          Em                    G
sleep, but I send a pure and evil thing when their youth is over

Em              G        C   Gmaj13
sending in some lost Oct-October

[The rest of the song follows the same pattern]

Lyrics:

I will bury you in time
When the sea begins to slide
Into this hole where I am smiling on your shoulder
You have buried my beliefs
Where all you sisters sleep
That there scent the purity will make
When the youth is over
Standing in some Oct-October

And I am breathing into you
It makes your features move
And they shimmer like balloons that fly above the ocean
All the world is waiting here
You can hear the children cheer
But they'll need you when you're near
The brink of complete implosion
Crown your king when your life is broken

Everything you are I'm tearing through
Everything you want I'm wanting too
I gave you more than I thought I could ever do
But I will never break you down

And if I was the king of all the kids
You'd you hear me singing in my spit
But all you would hear is the shit inside my burnt emotions
I will bury you in time
When the sea begins to slide
Into this hole where you and I will sing our songs unbroken
As the water starts its choking
Dee dee dee dee dee, etc.
