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.

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 1645 can be rotated to make 6 other scales. The 1st mode is itself.

2nd mode: Scale 1435 | Makam Huzzam | ||||

3rd mode: Scale 2765 | Lydian Diminished | ||||

4th mode: Scale 1715 | Harmonic Minor Inverse | ||||

5th mode: Scale 2905 | Aeolian Flat 1 | ||||

6th mode: Scale 875 | Locrian Double-flat 7 | ||||

7th mode: Scale 2485 | Harmonic Major |

The prime form of this scale is Scale 859

Scale 859 | Ultralocrian |

The heptatonic modal family [1645, 1435, 2765, 1715, 2905, 875, 2485] (Forte: 7-32) is the complement of the pentatonic modal family [595, 665, 805, 1225, 2345] (Forte: 5-32)

The inverse of a scale is a reflection using the root as its axis. The inverse of 1645 is 1741

Scale 1741 | Lydian Diminished |

Only scales that are chiral will have an enantiomorph. Scale 1645 is chiral, and its enantiomorph is scale 1741
