A second, a minute, and hour, a day goes by.
I'm hopin' just to be by your side.
I'm turnin' the handle
It won't open.
Don't make me wait, cause right now I need your smile.

Knock Knock

F             C             Am           G
When life had locked me out, I turned to you
So open the door.
F                 C                   G
Cuz' you're all I need right now it's true.
G                  F
Nothin' works like you.
F                             C
Little louder, little louder, little louder, knockin'
Am                        G
Little louder, little louder

(verso)
C            C/B           Am          G
A warm bath, a good laugh, an old song that you know by heart.
C            C/B          Am       G
I've tried it but they all leave me cold.
C          C/B            Am
So now I'm here waiting to see you,
G         C              C/B          Am
My remedy for all that's been hurting me.

(refrão)
Dm       Dm/E  F
You seem to    know the way
   C             G
To turn my frown upside down
Dm  Dm/E   F
You always know what to say
G
To make me feel like everything's ok.

F                             C
Little louder, little louder, little louder, knockin'
Am                        G
Little louder, little louder

(refrão 2x)

Little louder (3x) knockin'
Nothin' works like you, oh oh
Little louder (3x) knockin'

(refrão)
