[Intro]
Dm7 Cmaj7

[Verse]
Dm7
I don’t know what love is
Cmaj7
If I can’t have you here
G                 G6             F
I don’t know what love is
Fm                         C
I think that it’s just fear

[Verse]
Dm7
I don’t know the tempo
Cmaj7
Of my heart’s concerto
G
It all seems like a dream
G6                 F
It’s not, I know
Fm                                                 C
There’s something real out there for me

[Bridge]
Dm7
I swear I’ve seen an angel
Cmaj7
A paradise in blue
Cmaj7
Every color I choose
G                 G6                 F
But I don’t know what love is
Fm                                 C
But I think it might be you

[Verse]
Dm7
If I had the courage
Cmaj7
I’d know just what to do
G
Sometimes I have to crawl
G6                         F
And everyday I fall
Fm                                 C
Tryin’ just to stand by you

[Bridge]
Dm7
I swear I’ve seen an angel
Cmaj7
A paradise in blue
Cmaj7
Every color I choose
G                 G6                         F
But I don’t know what love is
Fm                         C
But I think it might be you
