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 2515 can be rotated to make 6 other scales. The 1st mode is itself.

2nd mode: Scale 3305 | Chromatic Hypophrygian | ||||

3rd mode: Scale 925 | Chromatic Hypodorian | ||||

4th mode: Scale 1255 | Chromatic Mixolydian | ||||

5th mode: Scale 2675 | Chromatic Lydian | ||||

6th mode: Scale 3385 | Chromatic Phrygian | ||||

7th mode: Scale 935 | Chromatic Dorian |

The prime form of this scale is Scale 743

Scale 743 | Chromatic Hypophrygian Inverse |

The heptatonic modal family [2515, 3305, 925, 1255, 2675, 3385, 935] (Forte: 7-20) is the complement of the pentatonic modal family [355, 395, 1585, 2225, 2245] (Forte: 5-20)

The inverse of a scale is a reflection using the root as its axis. The inverse of 2515 is 2419

Scale 2419 | Raga Lalita |

Only scales that are chiral will have an enantiomorph. Scale 2515 is chiral, and its enantiomorph is scale 2419
