I didn't bother with the messy beginning part, but it's not hard
to fake it or figure out an easy chord progression for it, like something
in key of D.

Anyways, this tab is to focus on the piano chords 
for the second part of the song.

If you're playing this on piano, for the A chord add in the B note
right next to the root A, this will help make some of that strange
resonance of the chords he's playing. If you want to do a melody type
riff just use the notes naturally in these chords/scale. It's easy to figure
out the back-and-forth part (try-ey-ey-ey) at the end of verses.

ASo, (x02220@1)you say there are spaces,
EOpen (022100@1)and wide.
ABelieve (x02220@1)me there's days,
ELonger (022100@1)than nights.
A (x02220@1)                         EAnd (022100@1)you will be happy, the minute you try...
DBut (xx0232@1)you don't try.
ENo (022100@1)you don't try.

And you speak of a fever,
That burns you inside.
As you explain to your mother,
How you wanted to die.
So she kisses your fingers,
Says "My Darling but why?
DWhen (xx0232@1)there is so much more...
EThere (022100@1)is so much more..."

Do you know there are spaces,
Open and wide.
Oh believe me, there's days,
Longer than nights.
And you will be happy,
If only you'd try. 
DOh (xx0232@1)won't you try,
E~
Oh won't you try...

Play some ugly dissonant chord here, an F#m with some wrong notes or whatever, and 
leave it open without resolving

The end. beautifully sad song.
