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).

Modes are the rotational transformation of this scale. Scale 1545 can be rotated to make 3 other scales. The 1st mode is itself.

2nd mode:
Scale 705

3rd mode:
Scale 75
Scale 75, Ian Ring Music TheoryThis is the prime mode
4th mode:
Scale 2085
Scale 2085, Ian Ring Music Theory


The prime form of this scale is Scale 75

The tetratonic modal family [1545, 705, 75, 2085] (Forte: 4-13) is the complement of the octatonic modal family [735, 1785, 1995, 2415, 3045, 3255, 3675, 3885] (Forte: 8-13)


The inverse of a scale is a reflection using the root as its axis. The inverse of 1545 is 525
