Scale 549: "Raga Bhavani"

Scale 549: Raga Bhavani, 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).

Common Triads

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

Parsimonious Voice Leading Between Common Triads of Scale 549. Created by Ian Ring ©2019 dm dm F F dm->F

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.



Modes are the rotational transformation of this scale. Scale 549 can be rotated to make 3 other scales. The 1st mode is itself.

2nd mode:
Scale 1161
Scale 1161: Bi Yu, Ian Ring Music TheoryBi Yu
3rd mode:
Scale 657
Scale 657: Epathic, Ian Ring Music TheoryEpathic
4th mode:
Scale 297
Scale 297: Mynic, Ian Ring Music TheoryMynicThis is the prime mode


The prime form of this scale is Scale 297

The tetratonic modal family [549, 1161, 657, 297] (Forte: 4-26) is the complement of the octatonic modal family [1467, 1719, 1773, 1899, 2781, 2907, 2997, 3501] (Forte: 8-26)


The inverse of a scale is a reflection using the root as its axis. The inverse of 549 is 1161
