Love is like a never-ending melody
Always have compared it to a symphony
A symphony conducted by the lighting of the moon
But our song of love is slightly out of tune
Once your kisses raised me to a fever pitch
Now the orchestration doesn't seem so rich
Seems to me you've changed the tune we used to sing
Like the bossa nova, love should swing
We used to harmonize, two souls in perfect time
Now the song is different and the words don't even 
rhyme
Cause you forgot the melody our hearts would always 
croon
So what good's a heart that's slightly out of tune
Tune your heart to mine the way it used to be
Join with me in harmony and sing a song of loving
We've got to get in tune again before too long
There'll be no desafinado
When your heart belongs to me completely
Then you won't be slightly out of tune
You'll sing along with me
> (Very jazzy, swingy, and upbeat version)
Translation 2:
Desafinado
If you say my singing is off key, my love
You would hurt my feelings, don't you see, my love
I wish I had an ear like yours, a voice that would 
behave
All I have is feeling and the voice God gave
You insist my music goes against the rules
Yes, but rules were never made for lovesick fools
I wrote this song for you don't care
It's a crooked song, ah, but my heart is there
The thing that you would see if you would play the part
Is even if I'm out of tume I have a gentle heart
I took your picture with my trusty Rolleiflex
And now all I have developed is complex
Possibly in vain, I hope you weaken, oh my love
And forget those rigid rules that undermine my dream of
A life of love and music with someone who'll understand
That even though I may be out of tune when I attempt to 
say
How much I love you all that matters is the message 
that I bring,
Which is, my dear, I love you
