Trying to find a folk/ medieval/renaissance instrumental music?

I have this english project on the middle ages, and I want to add music, I have already one song from the middle ages. I want something lively, like the background music of tinkerbells Lost Treasure Theme song (cant find the instrumental). I want any song that gives you the vision of people who dance at renaissance fairs with the harp, and flute, and everything, sounding lively! please help? I want to find one thats also free to download. thankyou!
