Verse one

 Secret heart, what are you made of? What are you so afraid of?

 Could it be three simple words? Or the fear of being overheard?

C fill #2 F G C --> Fill #1

What's wrong? Let her in on your secret heart

Verse two

 Secret heart why so mysterious? Why so sacred why so serious

 Maybe you're just acting tough. maybe you're just not man enough

C fill #2 F G C --> Fill #1

What's wrong? Let her in on your secret heart

Bridge

 This very secret you're trying to conceal

 Is the very same one you're dying to reveal

 Go tell her how you feel

Solo

Verse three

 Secret heart, come out and share it,

 This loneliness, few can bear it,

 Could it have something to do with,

Am Dm G C --> fill #2

Admitting that you just can't go through it alone,

 Let her in on your secret

 What's wrong

 Let her in on

Your secret heart
