I geeked out real hard on triads about a year and 1/2 ago. I think they very easily can structure a framework for approaching solo guitar playing , whether it's arranging , playing by ear or from a chart.
I'm particularly interested in being able to play from a chart on-the-fly, the way pianists do from fake books etc. I honestly believe triads are probably the most solid basis for getting closer to that goal. Anyway, I started a blog on this, but kind of got distracted from doing it for a few months . Anyway, I appreciate anyone's thoughts. Still working on a lot of these concepts, but I have basic ideas for creating chord scales for each chord type etc.
Here's an example of playing something from a chart I have at church. Didn't really work out so much ahead, other than reading through loads of other tunes:
