there's a regular at my local rennissance fair who plays the hammered dulcimer, and he's an expert at it. It's actually his full time job, and he travels internationally doing it (he's in italy at the moment, just got there from greece)
Hammered dulcimers are awesome.
I don't play any instrument, because i don't have a whole lot of manual dexterity, and i'm not very good at carrying a tune, but i would love to play several instruments, like piano, guitar, or really any stringed instrument.
