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} | 3 | 3 | 1.43 |
B | {11,3,6} | 3 | 3 | 1.43 | |
Minor Triads | bm | {11,2,6} | 2 | 3 | 1.57 |
Diminished Triads | c° | {0,3,6} | 2 | 3 | 1.57 |

The hexatonic modal family [2637, 1683, 2889, 873, 621, 1179] (Forte: 6-27) is the complement of the hexatonic modal family [603, 729, 1611, 1737, 2349, 2853] (Forte: 6-27)
The inverse of a scale is a reflection using the root as its axis. The inverse of 2637 is 1611
Scale 1611 | ![]() | Dacrimic |
Only scales that are chiral will have an enantiomorph. Scale 2637 is chiral, and its enantiomorph is scale 1611
