Here's an Irish reel in G major. Try to learn it by ear from the slow bit in the video. If you really need to cheat and look at sheet music (frowny face for you) you can find it at thesession.org. But resist.
I learned this from tenor banjo player Dave Cory. He's an amazing player. You can look at some of the projects he's doing here: http://www.bridgetown.ws/bio.htm
