Scale 307: "Raga Megharanjani"

Scale 307: Raga Megharanjani, 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 307. Created by Ian Ring ©2019 C+ C+ c#m c#m C+->c#m fm fm C+->fm C# C# c#m->C# C#->fm

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

2nd mode:
Scale 2201
Scale 2201: Ionagitonic, Ian Ring Music TheoryIonagitonic
3rd mode:
Scale 787
Scale 787: Aeolapritonic, Ian Ring Music TheoryAeolapritonic
4th mode:
Scale 2441
Scale 2441: Kyritonic, Ian Ring Music TheoryKyritonic
5th mode:
Scale 817
Scale 817: Zothitonic, Ian Ring Music TheoryZothitonic


This is the prime form of this scale.


The pentatonic modal family [307, 2201, 787, 2441, 817] (Forte: 5-21) is the complement of the heptatonic modal family [823, 883, 1843, 2459, 2489, 2969, 3277] (Forte: 7-21)


The inverse of a scale is a reflection using the root as its axis. The inverse of 307 is 2449

Only scales that are chiral will have an enantiomorph. Scale 307 is chiral, and its enantiomorph is scale 2449
