These are the common triads (major, minor, augmented and diminished) that you can create from members of this scale.
* Pitches are shown with C as the root
Triad Type | Triad* | Pitch Classes | Degree | Eccentricity | Closeness Centrality |
---|---|---|---|---|---|
Major Triads | D | {2,6,9} | 2 | 2 | 1 |
Minor Triads | am | {9,0,4} | 1 | 3 | 1.5 |
Augmented Triads | D+ | {2,6,10} | 1 | 3 | 1.5 |
Diminished Triads | f♯° | {6,9,0} | 2 | 2 | 1 |
Above is a graph showing opportunities for parsimonious voice leading between triads*. Each line connects two triads that have two common tones, while the third tone changes by one generic scale step.

The hexatonic modal family [1621, 1429, 1381, 1369, 683, 2389] (Forte: 6-34) is the complement of the hexatonic modal family [683, 1369, 1381, 1429, 1621, 2389] (Forte: 6-34)
The inverse of a scale is a reflection using the root as its axis. The inverse of 1621 is 1357
