Scale 403: "Raga Reva"

Scale 403: Raga Reva, 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 403 can be rotated to make 4 other scales. The 1st mode is itself.

2nd mode:
Scale 2249
Scale 2249: Raga Multani, Ian Ring Music TheoryRaga Multani
3rd mode:
Scale 793
Scale 793: Mocritonic, Ian Ring Music TheoryMocritonic
4th mode:
Scale 611
Scale 611: Anchihoye, Ian Ring Music TheoryAnchihoye
5th mode:
Scale 2353
Scale 2353: Raga Girija, Ian Ring Music TheoryRaga Girija


This is the prime form of this scale.


The pentatonic modal family [403, 2249, 793, 611, 2353] (Forte: 5-22) is the complement of the heptatonic modal family [871, 923, 1651, 2483, 2509, 2873, 3289] (Forte: 7-22)


The inverse of a scale is a reflection using the root as its axis. The inverse of 403 is 2353
