The song is in F minor, but has been transposed here to A minor for piano simplicity.
C
I was just a boy
Am
My father seemed a mountain then
C F
With a voice that could shake the seas
C Am
My mother's ghost hung across his shoulders
E F
And he said she was still watching over me
C
My brother was home
Am
Just returned on army leave
C F
Told his stories with a distant stare
C
And as it snowed
Am
The wind was howling through the trees
E F C
And I spent my night just listening by the fire
C, Am, Em, F, C, Am, E, F, E, Em, E, Em

Em F
My hands move the creases from my brow
C
Soft as a breath
G
It's like a feather
Em F
I dreamed of a lonely voice that night
C
Quiet as death
G
Outside my window
Em F
It sang a sad and lovely tune
C
Clear as a bell
G
Soft as a shiver
Em F
It said, I want you all the time
Fm C
It said, I want you all the time
C, Em, C, Em, C, Em, C, Em
C Em
Goodbye bad thoughts
C Em
I'm safe under covers
C Em
So goodbye bad thoughts
C Em
'Cause I'm safe under covers
C
Now I can see you again
Am, C, F, C, Am, E, F, Am, C, F, C, Am, E, F,
