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.



[Chorus:]
N.C. or /G
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

VERSE:

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.

[Chorus]

BRIDGE:

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

[Chorus x2]

Little louder x3 knockin'
Nothin' works like you, oh oh
Little louder x3 knockin'
