Brianna Fox spent her free time learning to play the harmonica so she could surprise her husband by playing a favorite song ...

And she goes, I don't care, kicked me out of the car, and they handed a kid each a harmonica. And they go, by the end of the five weeks, you'll learn how to play. And I'm like, great.

Schaman has been running harmonica tutorials at his clinic since 2007. He initially taught patients to play simple, familiar songs such as O Susanna by picking out individual notes.
