Sure, I'd agree, to some extent. I used to teach with a Solar System concept. Each note has a balance that's related to the oother notes. There's the note, or planet with the strongest gravitational pull towards the Sun, or home key. But chords are 1-3-5 steps of the scales, with several variations. These "Triads" have their own gravitational pulls either towards the Tonic (Sun), the ultimate destination,-- or the Dominant (Jupiter?), being the direct route home to the Tonic/Sun, or Earth if you want. BTW That's actually not a jazz guitar, play I play it as if it's one. It's MY jazz guitar -- Gibson ES 355.
