Overtone Scales on Stage
Video 1:[1] Neck of a 10-string E9-pedal steel guitar:

The fret marks guide the player to 12edo intervals, while the intervals between the strings are often tuned differently (i.e. just intervals, meantone tuning, various best-practice tunings)

7 Levels of Jazz Harmony

Neely-intonalism

Adam Neely; The 7 Levels of Jazz Harmony, Intonalism [9:12], Xenharmonic [10:46]

In 2020 music educator Adam Neely picked up the term intonalism and used it in his Seven Levels of Jazz Harmony, with a somewhat different and rather ambiguous intent, where he seemed to describe the use of a tempered scale (often 12edo) for the lead melody of a piece. The current melody note at any given point in time is then treated as a reference pitch, and the current backing chord uses pure just intonation, tuned relative to the current reference pitch. In a sense this is an inverse form of adaptive just intonation where the bass line adjusts to a tempered scale and the melody and harmony notes tune to it.

To distinguish this form of intonalism from the other, you could call it Neely-intonalism.[idiosyncratic term]

Fig.5 shows a comparison of four augmented chords that sound quite different.
Listen to the following audio examples...

Fig.6 shows a comparison of five different diminished chords.

Fig.8 shows four varieties of what I call crossover (x-over) triads, all of which are rooted at 0 cents. Crossover triads are neither diminished nor augmented. From a major perspective, x-over chords incorporate a flattened third and a raised fifth.

Unlike minor or major chords, crossover triads are neither diminished nor augmented and do not incorporate a pure fifth.
