Scale 367: "Aerodian"

Scale 367: Aerodian, Ian Ring Music Theory

Bracelet Diagram

The bracelet shows tones that are in this scale, starting from the top (12 o'clock), going clockwise in ascending semitones. The "i" icon marks imperfect tones that do not have a tone a fifth above. Dotted lines indicate axes of symmetry.

Tonnetz Diagram

Tonnetz diagrams are popular in Neo-Riemannian theory. Notes are arranged in a lattice where perfect 5th intervals are from left to right, major third are northeast, and major 6th intervals are northwest. Other directions are inverse of their opposite. This diagram helps to visualize common triads (they're triangles) and circle-of-fifth relationships (horizontal lines).

Modes are the rotational transformation of this scale. Scale 367 can be rotated to make 6 other scales. The 1st mode is itself.

2nd mode:
Scale 2231

3rd mode:
Scale 3163
Scale 3163: Rogian, Ian Ring Music TheoryRogian
4th mode:
Scale 3629
Scale 3629: Boptian, Ian Ring Music TheoryBoptian
5th mode:
Scale 1931
Scale 1931: Stogian, Ian Ring Music TheoryStogian
6th mode:
Scale 3013
Scale 3013: Thynian, Ian Ring Music TheoryThynian
7th mode:
Scale 1777
Scale 1777: Saptian, Ian Ring Music TheorySaptian


This is the prime form of this scale.


The heptatonic modal family [367, 2231, 3163, 3629, 1931, 3013, 1777] (Forte: 7-Z36) is the complement of the pentatonic modal family [151, 737, 1801, 2123, 3109] (Forte: 5-Z36)


The inverse of a scale is a reflection using the root as its axis. The inverse of 367 is 3793

Only scales that are chiral will have an enantiomorph. Scale 367 is chiral, and its enantiomorph is scale 3793
