A standard arrangement of this classic tune. Check out the licks for some great options. There's plenty of Crosspicking, Bluegrass, and Celtic licks. There's also some options that show how you can play the same phrase in a closed position(no open strings). This is a great exercise for your left hand. These particular licks are in what we call second position. Index finger gets the notes on 2nd fret, middle finger gets the notes on the 3rd fret, ring finger gets notes on 4th fret, and pinky gets the notes on the 5th fret.
