Season is open, and we’re on the prowl for some hot licks! Let’s also stalk out some harmony notes in this catchy fiddle tune, and capture a second solo to put on the wall!
What an absolute gem of a lesson! Chock-full of good stuff, and awesome sauce thrown in fer good measure. This is build on a great little melody and catchy B section, there is so much in here for me to practice on…
But… 2 Mandolin harmony? Now you are just plain showin’ off! 
I am printing this lesson right - NOW! 
Thanks for your efforts on bringing us this one, @BanjoBen 
So timely, Ben! I’ve been working on this basic tune for over a month and now wondering how I can flavor it up…you’ve given me the answer! And harmony?
It doesn’t get any better than this! Thanks so much!
