The Exciting Universe Of Music Theory

presents

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).

These are the common triads (major, minor, augmented and diminished) that you can create from members of this scale.

Above is a graph showing opportunities for parsimonious voice leading between triads^{*}. Each line connects two triads that have two common tones, while the third tone changes by one generic scale step.

Modes are the rotational transformation of this scale. Scale 3629 can be rotated to make 6 other scales. The 1st mode is itself.

2nd mode: Scale 1931 | Stogian | ||||

3rd mode: Scale 3013 | Thynian | ||||

4th mode: Scale 1777 | Saptian | ||||

5th mode: Scale 367 | Aerodian | This is the prime mode | |||

6th mode: Scale 2231 | Macrian | ||||

7th mode: Scale 3163 | Rogian |

The prime form of this scale is Scale 367

Scale 367 | Aerodian |

The heptatonic modal family [3629, 1931, 3013, 1777, 367, 2231, 3163] (Forte: 7-Z36) is the complement of the pentatonic modal family [151, 737, 1801, 2123, 3109] (Forte: 5-Z36)

The inverse of a scale is a reflection using the root as its axis. The inverse of 3629 is 1679

Scale 1679 | Kydian |

Only scales that are chiral will have an enantiomorph. Scale 3629 is chiral, and its enantiomorph is scale 1679
