Scale 369: "Laditonic"

Scale 369: Laditonic, 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.

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 369 can be rotated to make 4 other scales. The 1st mode is itself.

2nd mode:
Scale 279
Scale 279: Poditonic, Ian Ring Music TheoryPoditonicThis is the prime mode
3rd mode:
Scale 2187
Scale 2187: Ionothitonic, Ian Ring Music TheoryIonothitonic
4th mode:
Scale 3141
Scale 3141: Kanitonic, Ian Ring Music TheoryKanitonic
5th mode:
Scale 1809
Scale 1809: Ranitonic, Ian Ring Music TheoryRanitonic


The prime form of this scale is Scale 279

The pentatonic modal family [369, 279, 2187, 3141, 1809] (Forte: 5-13) is the complement of the heptatonic modal family [375, 1815, 1905, 2235, 2955, 3165, 3525] (Forte: 7-13)


The inverse of a scale is a reflection using the root as its axis. The inverse of 369 is 465
