Dave Woods,
I'm now getting around more in your site. It's beginning to look very promising to me as a teaching/learning tool. I read today about the origins of the key structure based on naturally occurring harmonics. This was new to me, and very nice to know.
I'm looking forward to using the basic key positions as jump off points for arps and scales and melodic ideas. I like the way you imbed everything within these key positions. I've heard you many times alluding to this, but now it's getting "up close and personal".
Thank you for all your work and for sharing it with us.
