All...
We got together last Saturday for a few hours. I went through some basics with him. I could tell that in some ways I was causing his eyes to gloss over, but in other ways, I could see the light bulb begining to light.

I started small, talking about scales. Worked on the Major and Minor patterns with him. Then, I setup a metronome so he and I could march up and down the patterns in beat. Turned out good. He wants to start doing this every saturday. Not sure that's going to work out with the wife, but, good to see that he's showing an interest in leaning some theory.

I think I'm going to try to get him very familiar with the Major, Minor and Harmonic Minor scales. Key's A, E and probably C. I like A and E because they are on open strings.
