here are the names of the piano chords in the original key of Bbm  
verses and chorus: Bbm7 Ebm9 Ab Gb Ab/Gb bass  
 
  
 
Bridge: Db6 Eb Ab Db 
 
  
 
Semisonic plays the song live in the key of Am, mainly because 
Dan only uses the standard tuning of EADGBE for his guitars. 
 
  
 
or you can play the guitar part capo'ed up one fret, using these 
transposed chords (as though the capo first fret were now called 
the 0th fret or open string.) There is a pattern of two notes 
alternating within each chord, open G and A. So each chord has 
three voicings, the first with a G in it, second with A, third with G again.

Secret Smile 
 
Nobody knows it but you've got a secret smile 
And you use it only for me 
Nobody knows it but you've got a secret smile 
And you use it only for me 
 
So use it and prove it 
Remove this whirling sadness 
I'm losing, I'm bluesing 
But you can save me from madness 
 
Nobody knows it but you've got a secret smile 
And you use it only for me 
Nobody knows it but you've got a secret smile 
And you use it only for me 
 
So save me I'm waiting 
I'm needing, hear me pleading 
And soothe me, improve me 
I'm grieving, I'm barely believing now, now 
 
When you are flying around and around the world 
And I'm lying alonely 
I know there's something sacred and free reserved 
And received by me only
