[Verse]
G           Am7             C
This is my five string serenade
G           Am7          C
Beneath the water I (we) play
                  (verse 4)
G                  Am7             C
And while (though) I'm playing for you
         (verse 4)
G                Am7          C     
It could (might) be raining there too
       (verse 3+4)

[Chorus]
C                  D
And on my easel I drew
C                       D
While I was thinking of you
C                      D
And on the roof of my head
C                         D
In came my five string serenade

[Ending]
G           C               G (strum)
This is my five string serenade
