Harmonica

I bought a cheap set of harmonicas a year or two ago but never did anything with them.  Got them out yesterday and messed around with them (in a holder; I don't know what you call those things that go around your neck) while playing uke.  I probably won't ever be able to do much more on one than breath in and out and modulate it up and down a little bit, but it was pretty fun and adds a bit of depth to a jam.
