Scale 287: "Gynimic"

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).

Common Triads

These are the common triads (major, minor, augmented and diminished) that you can create from members of this scale.

Modes are the rotational transformation of this scale. Scale 287 can be rotated to make 5 other scales. The 1st mode is itself.

2nd mode:
Scale 2191
Scale 2191: Thydimic, Ian Ring Music TheoryThydimic
3rd mode:
Scale 3143
Scale 3143: Polimic, Ian Ring Music TheoryPolimic
4th mode:
Scale 3619
Scale 3619: Thanimic, Ian Ring Music TheoryThanimic
5th mode:
Scale 3857
Scale 3857: Ponimic, Ian Ring Music TheoryPonimic
6th mode:
Scale 497
Scale 497: Kadimic, Ian Ring Music TheoryKadimic


This is the prime form of this scale.


The hexatonic modal family [287, 2191, 3143, 3619, 3857, 497] (Forte: 6-Z37) is the complement of the hexatonic modal family [119, 1799, 2107, 2947, 3101, 3521] (Forte: 6-Z4)


The inverse of a scale is a reflection using the root as its axis. The inverse of 287 is 3857
