I just read an interesting article on COPD and Harmonicas. Did you know that some COPD support groups utilize harmonicas as part of their rehabilitation?

I think this sounds like a FUN and creative way to work on better breathing.
What do you think? Furthermore, are you a musician? What instruments do you play and what if any therapeutic relief do you get from your creative outlet?
