Scale 143

Scale 143, 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 143 can be rotated to make 4 other scales. The 1st mode is itself.

2nd mode:
Scale 2119
Scale 2119, Ian Ring Music Theory
3rd mode:
Scale 3107
Scale 3107, Ian Ring Music Theory
4th mode:
Scale 3601
Scale 3601, Ian Ring Music Theory
5th mode:
Scale 481
Scale 481, Ian Ring Music Theory


This is the prime form of this scale.


The pentatonic modal family [143, 2119, 3107, 3601, 481] (Forte: 5-5) is the complement of the heptatonic modal family [239, 1927, 2167, 3011, 3131, 3553, 3613] (Forte: 7-5)


The inverse of a scale is a reflection using the root as its axis. The inverse of 143 is 3617

Only scales that are chiral will have an enantiomorph. Scale 143 is chiral, and its enantiomorph is scale 3617
