WEll the melody is:
5._____________|___________|
6.______5b__5b_|____5b__5b~|
7.____5___5___5|___5__5____|
8._~5L_________|~5L________|
:repeat
But I usually add a harmony not in there.
5.________5~5a___5~5a__|______5~5a___5~5a~|
6._____5b_5b~~___5b~~__|___5b_5b~~___5b~~~|
7._____5_______5______5|___5_______5______|
8._~5L_________________|~5L_______________|
:repeat
And also if the Guitar player is playing the melody(Like me and Dale watson used to do)I would play even another harmony up...so you just start one string higher.
Have fun.
