The C#5 is just a slide to the third fret while still 

in the A5 fingering 

       A5                      C#5                     A5     C#5 
I know nothing? about this woman and everything I do is wrong 
    A5                      C#5            A5        C#5 
Sometimes it?s hard to fathom just what day she?s on 
         A5                    C#5                    A5    C#5 
I find a pretty little mood ring at the local five and dime 
           A5                  C#5            A5    C#5 
It?s gonna solve all my problems for a dollar 99 

Chorus: 
            G5                    D5 
If it turns black, I should turn back 
            C5                     D5 
If it turns red, she liked what I said 
            G5                         D5 
If it turns blue, I should leave her alone 
            C5                     D5 
If it turns green, she wants me I know 
               A5     C#5 
She wants me I know 

I followed the instructions, I read them word for word 

I memorized the color charts cause I wanted to be sure 

I told her, Baby it?s the thought that counts, when I slipped it on her hand 

Then I crossed my fingers, with this ring I?ll understand 

Chorus 

Bridge: 
E5           C5 
Whoa all the things she?s not saying  
     E5          C5          D5 
I?ll know as the colors are changing 


Chorus
