I have never played a harp. I don’t think I’ve ever even touched a harp, actually. It’s not really the kind of instrument you find lying around in a friend’s basement or an unused corner of a school music room. They’re rather expensive. And big, and presumably heavy though not so heavy that you'd need tow trucks or anything. So not terribly common, basically. Not that I would know where to start, at all, if I did get my hands on one. There are strings, yes, and I play some stringed instruments, but I really don’t think that qualifies me to go anywhere near a harp.
