46 tone equal temperament
The 46 equal temperament, often abbreviated 46-tET, 46-EDO, or 46-ET, is the scale derived by dividing the octave into 46 equally-sized steps. Each step represents a frequency ratio of 26.087 cents, an interval close in size to 66/65, the interval from 13/11 to 6/5.
46et tempers out 507/500, 91/90, 686/675, 2048/2025, 121/120, 245/243, 126/125, 169/168, 176/175, 896/891, 196/195, 1029/1024, 5120/5103, 385/384, and 441/440 among other intervals, with varied consequences it would take a very long article to describe. Rank two temperaments it supports include sensi, valentine, shrutar, rodan, leapday and unidec. The 11-limit minimax tuning for valentine temperament, (11/7)^(1/10), is only 0.01 cents flat of 3/46 octaves. In the opinion of some, 46et is the first equal division to deal adequately with the 13-limit, though others award that distinction to 41edo. In fact, while 41 is a zeta integral edo but not a zeta gap edo, 46 is zeta gap but not zeta integral.
The fifth of 46 equal is 2.39 cents sharp, which some people (eg, Margo Schulter) prefer, sometimes strongly, over both the just fifth and fifths of temperaments with flat fifths, such as meantone. It gives a characteristic bright sound to triads, distinct from the mellowness of a meantone triad.
46edo can be treated as two 23edo's separated by an interval of 26.087 cents.

Shrutar22 as srutis describes a possible use of 46edo for Indian music.

- 15/13 (and its inversion 26/15) appears twice on the list. 9\46edo is closest to 15/13 by a hair; 10\46edo represents the difference between, for instance, 46edo's 15/8 and 13/8, and is more likely to appear in chords actually functioning as 15/13. This discrepancy occurs because 46edo is not consistent in the 15-limit.
Combining ups and downs notation with color notation, qualities can be loosely associated with colors:
| quality | color | monzo format | examples |
|---|---|---|---|
| downminor | zo | {a, b, 0, 1} | 7/6, 7/4 |
| minor | fourthward wa | {a, b}, b < -1 | 32/27, 16/9 |
| upminor | gu | {a, b, -1} | 6/5, 9/5 |
| downmid | ilo | {a, b, 0, 0, 1} | 11/9, 11/6 |
| upmid | lu | {a, b, 0, 0, -1} | 12/11, 18/11 |
| downmajor | yo | {a, b, 1} | 5/4, 5/3 |
| major | fifthward wa | {a, b}, b > 1 | 9/8, 27/16 |
| upmajor | ru | {a, b, 0, -1} | 9/7, 12/7 |
All 46edo chords can be named using ups and downs. Here are the zo, gu, ilo, yo and ru triads:
| color of the 3rd | JI chord | notes as edosteps | notes of C chord | written name | spoken name |
|---|---|---|---|---|---|
| zo | 6:7:9 | 0-10-27 | C Ebv G | C.vm | C downminor |
| gu | 10:12:15 | 0-12-27 | C Eb^ G | C.^m | C upminor |
| ilo | 18:22:27 | 0-13-27 | C Eb^^ G | C.v~ | C downmid |
| yo | 4:5:6 | 0-15-27 | C Ev G | C.v | C downmajor or C dot down |
| ru | 14:18:27 | 0-17-27 | C E^ G | C.^ | C upmajor or C dot up |

Approximation to Mode 8 of the Harmonic Series
46edo represents overtones 8 through 16 (written as JI ratios 8:9:10:11:12:13:14:15:16) with degrees 0, 8, 15, 21, 27, 32, 37, 42, 46. In steps-in-between, that's 8, 7, 6, 6, 5, 5, 5, 4.
8\46edo (208.696¢) stands in for frequency ratio 9:8 (203.910¢).
7\46edo (182.609¢) stands in for 10:9 (182.404¢).
6\46edo (156.522¢) stands in for 11:10 (165.004¢) and 12:11 (150.637¢).
5\46edo (130.435¢) stands in for 13:12 (138.573¢), 14:13 (128.298¢) and 15:14 (119.443¢).
4\46edo (104.348¢) stands in for 16:15 (111.731¢).
