you too! your site is so cute

how moo-citing! ... ... all seriousness aside, somehow I never knew about the hurdy gurdy. I always thought that was the violin i was hearing

It's a pretty forgotten instrument, falling out of style after the baroque period I believe. But it's going through a real revival! The giveaway is the clacking of keys, and the continuous sound which isn't possible witha violin. But they are quite similar, yes!
