This is a theme Joe returns to time and time again, throughout the video. If you want to write a passage of jazz stuff ... link it with common note, or a common phrase #gold
Choice of keys
"Do not play more than one or two tunes together in the key of E, A and D ... my theory is that you start getting the drone sound ... and it doesn't matter what you play, how beautiful the chords are... you will put an audience to sleep - and yourself too! ... if you play in the key of A, play the next piece in the key of C or Eb or Bb, even though we all know that those are the prettiest sounding keys on the guitar" [4'45"]
Colour tones and choice of form
If you use colour tones, it's a good idea to follow suit, keep the same form [11'45"]
Never play anything that's hard!
These are things on the guitar that you should know how to do! Easy things! Never play anything that's hard! If it's hard, don't play it! [40:30]
That's great advice. Don't tie yourself up in knots trying to play chord notes you don't need to! Joe has a 'simple' system of chord forms, that he can grab quickly, beneath any given bass line. So, when describing a "7th" (he's actually playing a simplified 6th or 13th). This flexible system prefers the ability to move and flow, in tune with his inner musical ear, over adherence to strict theoretical correctness! Go Joe!
