Am                       F
so go ahead and lie to yourself,
                           G
and pretend that you’re a ray of light,
                G
when you’re a broken candle,

Am                             F
  you’re keeping time with yourself,
                              G
when did it all start moving way too fast,
    G
for you to handle,

        Am                   F
you’re short on breath but heavy on time,
     G                        Am      G
you lost the words but you found the rhyme,
      F               G
it’s all just poetry now,


the walls are singing,
Am    F       G
hallelujah amen,

the walls are singing,
Am   F       G
hallelujah amen,

Am                   F
it’s so dark in the room,
                       G
and the ceilings are high,

you know the feeling,
                      Am
you’ve been here before,

Am                      F
But it’s a broken old pew,
                     G
and it’s an echoing cry,
                      Am
don’t sell yourself short,
                 F
on breath and heavy on time,
     G                       Am        G
you lost the words but you found the rhyme,
      F               G
it’s all just poetry now,


the walls are singing,
Am    F      G
hallelujah amen,

the walls are singing,
Am    F      G
hallelujah amen,

Now's the part where it gets all intense and in the latest version Sam does his speech. 
Basically the chords are

Am F G

or something along those lines.

    Am          F
in time you’ll find,
               G                       G
this life’s a painting and you’re the artist,
    Am        F
so open your eyes,
                G                  G
it’s never too late to clear your canvas,

     Am
so paint me jealous,
F
paint me rage,
     G                  Am    G
for God’s sake paint me anything,
      F
just paint,
              G
your brush awaits,

Am   F        G
hallelujah amen,

the walls sing you to sleep,
Am   F        G
hallelujah amen,
                    Am        F       G
one secret meant to keep you safe tonight,
                   Am        F       G
I swear that everything will be alright
