Scale 73

Scale 73, 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.

Since there is only one common triad in this scale, there are no opportunities for parsimonious voice leading between triads.


Modes are the rotational transformation of this scale. Scale 73 can be rotated to make 2 other scales. The 1st mode is itself.

2nd mode:
Scale 521
Scale 521, Ian Ring Music Theory
3rd mode:
Scale 577
Scale 577, Ian Ring Music Theory


This is the prime form of this scale.


The tritonic modal family [73, 521, 577] (Forte: 3-10) is the complement of the nonatonic modal family [1759, 1787, 2011, 2927, 2941, 3053, 3511, 3803, 3949] (Forte: 9-10)


The inverse of a scale is a reflection using the root as its axis. The inverse of 73 is 577
