Can you learn to play banjo in open C position? Yes you CAN! I created this lesson as an introductory (but certainly not shallow) guide to get you kickstarted playing in the tremendously fun key of C. We’ll use a 3-level version of “Will the Circle Be Unbroken” as our example, but the point is not to learn the breaks—rather, the actual process behind writing them.

Haa. One step head of you on this 
but thanks!
