Oh man, I would be all over learning to play a medieval instrument; I used to play viola and classical guitar, and still noodle at keyboard, (although am out of practice) so I expect I could pick up the basics without too much difficulty, and I still play soprano recorder (albeit mostly to play anime or computer game tunes by ear, probably not what the SCA has in mind). But hey, I am not picky about what kind of cool thing I'd learn to do--I just think it sounds like a lot of fun, and would like to hang out with people. I should probably look up the local group and email their contact person and ask how people usually go about joining...
