Didn't realize the 'force bond' between Rey and Kylo Ren was referred to as a Dyad?!
Another meaning of a dyad is the placing of a (diatonic for now) 3rd, 5th, or Tri-Tone above the bass notes of our Major or Minor scale degrees.
Usually just 3rds gets stacked on top --- but the Rule of the Octave/Partimento version is slightly different and waaaaaaayyy more satisfying!
FYI:
The keyboard version I've been learning starts with 3-note chords right away, so starting with bass notes and then adding a 2nd (then 3rd voice) is part of my attempt at adaptation for the fretboard.
Initially I wasn't sure this was really going to work on the guitar, and assumed I'd go back to happily plunking it out at the piano -- but once I added the 2nd voice (following the 'Rule Of The Octave' per Dr. Mortenson's wonderful online course), I was sold!
Most of these will be diatonic 3rds stacked on top of the bas note/scale degree, except for:
Going up: Scale degree 4 gets a 5th on top, and scale degree 7 gets a Tri-Tone on top
Going down: moving from scale degree 5 to 4, just the bass note moves down (the 2nd voice from scale degree 5 remains)
Root dyads (C) are in GREEN
