Got a harp, now what?

Hey guys,
So I'm an Elf Hunter, and I got a harp from a character as a reward in the Epic book quest line. Which is nice and all...but it says I don't have a certain skill that I'd need to play it. I think it would be fun to play it sometime, but I'm unsure of how to go about doing that. What do you guys know about that?

Thanks!
