Thanks Chris- gives me a lot to think about. I am halfway through Improvisation in a Major Key. Great info. Not what I am used to. I have memorized scale patterns. Never paid much attention to the notes. I also do not know all the notes on the fretboard so this is proving challenging- especially when you change position. I memorize, one pattern starting in one spot- usually the root note on the low (thick) E string. So you are saying to play the notes for each chord to chase the changes. Seems like a lot of work. Not sure I will ever be able to do all of that. Also, many songs are not just A, D, E so chasing chords seems hard. I would like to learn this but playing a minor penta in blues seems more my speed. I can do that pretty easily up and down the neck. Again, I don't know notes when I am playing, just the 5 shapes/patterns. I can however hear the root note in various locations and land on it at the right times usually.
