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 2421 can be rotated to make 6 other scales. The 1st mode is itself.

2nd mode: Scale 1629 | Synian | ||||

3rd mode: Scale 1431 | Phragian | ||||

4th mode: Scale 2763 | Mela Suvarnangi | ||||

5th mode: Scale 3429 | Marian | ||||

6th mode: Scale 1881 | Katorian | ||||

7th mode: Scale 747 | Lynian | This is the prime mode |

The prime form of this scale is Scale 747

Scale 747 | Lynian |

The heptatonic modal family [2421, 1629, 1431, 2763, 3429, 1881, 747] (Forte: 7-28) is the complement of the pentatonic modal family [333, 837, 1107, 1233, 2601] (Forte: 5-28)

The inverse of a scale is a reflection using the root as its axis. The inverse of 2421 is 1491

Only scales that are chiral will have an enantiomorph. Scale 2421 is chiral, and its enantiomorph is scale 1491
