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.

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).

The pentatonic modal family [1377, 171, 2133, 1557, 1413] (Forte: 5-24) is the complement of the heptatonic modal family [687, 1401, 1509, 1941, 2391, 3243, 3669] (Forte: 7-24)


The inverse of a scale is a reflection using the root as its axis. The inverse of 1377 is 213

Scale 213Scale 213, Ian Ring Music Theory


Only scales that are chiral will have an enantiomorph. Scale 1377 is chiral, and its enantiomorph is scale 213
