Bringing the melody and bass runs out of basic chords.

NOTE: This ISN'T about augmented chords ... wrong term used. Sorry. As requested, some illustrations of my flat-picking rhythm styling with melody and bass lines illustrated. My style is, I believe, pretty simplistic. and there are many far better guitarists than I - it is just something that evolved over many years, but I hope this helps. As I say in the video, don't bother to copy me, or anyone else - just let the music drive you and develop your own style.
