Welcome to the Attack of the Drones........the next Star Wars movie.....OK, back to the lesson, I love drones and use them frequently in my lead playing. They are like little doors, or portals, into a new dimension of guitar world! The open dot-circle means to play that string open...and the closed-circle means to play the note with your finger, and the specific one is written on the extreme left. (The low open string is always played with the thumb) On the ones with 2-3 notes stacked and played together, you'll have to use a partial barre with one finger to make it work. Get these down, they will give your playing a unique quality that few others have!
