I've had my fiddle for 30 years and never played it until last year when I took about 6 months of lessons. I really enjoyed it but still have a ways to go!

I bought several videos here, http://www.onlinelessonvideos.com/home.php?cat=273 . This guys is really good. And I did a 3 month membership here http://www.academyofbluegrass.com/publicfiddle

As for how-to books I really like http://www.amazon.com/Complete-Idiots-Guide-Playing-Fiddle/dp/1592577687 and http://www.amazon.com/Old-Time-Fiddle-Complete-Ignoramus-Book/dp/1883206480

And finally, I have found YouTube can sometimes offer up a gem amidst the ocean of rough!

Good luck and enjoy your fiddle!!!
