Scale 2177, 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

There are no common triads (major, minor, augmented and diminished) that can be formed using notes in this scale.


Modes are the rotational transformation of this scale. Scale 2177 can be rotated to make 2 other scales. The 1st mode is itself.

2nd mode:
Scale 49
Scale 49, Ian Ring Music Theory
3rd mode:
Scale 259
Scale 259, Ian Ring Music Theory


The prime form of this scale is Scale 35

Scale 35Scale 35, Ian Ring Music Theory


The tritonic modal family [2177, 49, 259] (Forte: 3-4) is the complement of the nonatonic modal family [959, 2023, 2527, 3059, 3311, 3577, 3703, 3899, 3997] (Forte: 9-4)


The inverse of a scale is a reflection using the root as its axis. The inverse of 2177 is 35

Only scales that are chiral will have an enantiomorph. Scale 2177 is chiral, and its enantiomorph is scale 35
