The Exciting Universe Of Music Theory

more than you ever wanted to know about...

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 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 2271 can be rotated to make 7 other scales. The 1st mode is itself.

2nd mode: Scale 3183 | Mixonyllic | ||||

3rd mode: Scale 3639 | Paptyllic | ||||

4th mode: Scale 3867 | Storyllic | ||||

5th mode: Scale 3981 | Phrycryllic | ||||

6th mode: Scale 2019 | Palyllic | ||||

7th mode: Scale 3057 | Phroryllic | ||||

8th mode: Scale 447 | Thyphyllic | This is the prime mode |

The prime form of this scale is Scale 447

Scale 447 | Thyphyllic |

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

The inverse of a scale is a reflection using the root as its axis. The inverse of 2271 is 3939

Scale 3939 | Dogyllic |

Only scales that are chiral will have an enantiomorph. Scale 2271 is chiral, and its enantiomorph is scale 3939
