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 | G | {7,11,2} | 1 | 1 | 0.5 |
Diminished Triads | g♯° | {8,11,2} | 1 | 1 | 0.5 |
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 [2949, 1761, 183, 2139, 3117, 1803] (Forte: 6-Z11) is the complement of the hexatonic modal family [303, 753, 1929, 2199, 3147, 3621] (Forte: 6-Z40)
The inverse of a scale is a reflection using the root as its axis. The inverse of 2949 is 1083
Scale 1083 | ![]() |
Only scales that are chiral will have an enantiomorph. Scale 2949 is chiral, and its enantiomorph is scale 1083
