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 897 can be rotated to make 3 other scales. The 1st mode is itself.

2nd mode:
Scale 39
Scale 39, Ian Ring Music TheoryThis is the prime mode
3rd mode:
Scale 2067
Scale 2067, Ian Ring Music Theory
4th mode:
Scale 3081
Scale 3081, Ian Ring Music Theory


The prime form of this scale is Scale 39

The tetratonic modal family [897, 39, 2067, 3081] (Forte: 4-4) is the complement of the octatonic modal family [447, 2019, 2271, 3057, 3183, 3639, 3867, 3981] (Forte: 8-4)


The inverse of a scale is a reflection using the root as its axis. The inverse of 897 is 57

Scale 57Scale 57, Ian Ring Music Theory


Only scales that are chiral will have an enantiomorph. Scale 897 is chiral, and its enantiomorph is scale 57
