I'm pretty sure the Intro is Just a progression of G5 - F#5 - B5

But I'm not sure about this, just improvise.

D5                 B5
Stick and stones, a few clam living bones
G5                      B5
Salt and water melt my skin
D5                       B5
If you don't set sail, you'll end up in the belly of a whale
G5                               B5
No swallow saint will mock your grave

G5                     B5
Every light of every day
G5                B5
It's a way into decay
            G5     F#5     B5
But I won't cry myself to sleep
            G5      F#5    B5
'Cause my soul no longer weeps
       G5                 F#5         B5
But my body lies in the heart of the sea

Darkness breaks and we heard the morning wakes
She marks us weary as we drown
Show no remorse as you will make a beautiful course
Let's do the one you love the most

Every light of every day
It's a way into decay

Don't fornicate
With the one you love to hate
You'll wind up dead before she vows

But I won't cry myself to sleep
'Cause my soul no longer weeps
While my body lies in the heart of the sea

G5         F#5     B5
Another useless confrontation
G5         F#5     B5
Leaves any A-class confirmation
G5            F#5
Now the end appears
B5                          
And my eyes are filled with fear

B5
I am blind, I am blind, take me up before I die
             G5               F#5        B5
Don't wanna end up in the heart of the sea
B5
Oh, I am blind, I am blind, take me up before I die
            G5               F#5        B5
I don't wanna end up in the heart of the sea

Now the lesson is lesson is learnt
Don't you remember the fire from your burns
Walk, it's better even truly feel

But I won't cry myself to sleep
'Cause my soul no longer weeps
While my body lies in the heart

But I won't cry myself to sleep
'Cause my soul no longer weeps
While my body lies in the heart of the sea
Heart of the sea
