R Basic Start Guitar

I teach to learn, novice player, some professional experience with local or traveling acts, just friends mostly, worked with song and dance man tour for few months. I've only taught casually to curious starter beginners, but they've never returned, because, I told them, I didn't charge, that I would gladly give anyone the information I've acquired. I'm not certified to teach, never won any awards, just amateur/professional nothing big. I will build a study lesson for each beginner from their start, giving them what information, I develop to what I perceive would help them, what's helped me. Mostly beginners chords, simple melody, basic theory.
