46 equal divisions of the octave (abbreviated 46edo or 46ed2), also called 46-tone equal temperament (46tet) or 46 equal temperament (46et) when viewed under a regular temperament perspective, is the tuning system that divides the octave into 46 equal parts of about 26.1 ¢ each. Each step represents a frequency ratio of 2^1/46, or the 46th root of 2.

Theory

In the opinion of some, 46edo is the first equal division to deal adequately with the 13-limit, though others award that distinction to 41edo or 53edo. In fact, while 41 is a zeta peak and zeta integral edo but not a zeta gap edo, 46 is zeta gap but not zeta peak or zeta integral, and 53 is a strict zeta edo. Like 41 and 53, 46 is distinctly consistent in the 9-odd-limit, and it is consistent to the 13-odd-limit or the no-15 no-19 23-odd-limit. 46edo's fifth is slightly sharp of just, which some people (e.g. Margo Schulter) prefer, sometimes strongly, over both the just fifth and fifths of temperaments with flat fifths, such as meantone. Many say that sharp fifths give a characteristic bright sound to 5-limit triads, and consider the sound of meantone triads to be more mellow in comparison.

Rank-2 temperaments it supports include sensi, valentine, shrutar, rodan, leapday and unidec. The 11-odd-limit minimax tuning for valentine, (11/7)^1/10, is only 0.01 cents flat of 3\46 octaves.

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

Interval quality and chord names in color notation

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
dupminor	ilo	{a, b, 0, 0, 1}	11/9, 11/6
dudmajor	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. Alterations are always enclosed in parentheses, additions never are. Ups or downs immediately after the chord root affect the 3rd, 6th, 7th, and/or the 11th (every other note of a stacked-3rds chord 6-1-3-5-7-9-11-13). Here are the zo, gu, ilo, lu, 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 vEb G	Cvm	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^^m	C dupminor
lu	22:27:33	0-14-27	C vvE G	Cvv	C dudmajor or C dud
yo	4:5:6	0-15-27	C vE G	Cv	C downmajor or C down

Notation

Sagittal notation

This notation uses the same sagittal sequence as 39-EDO.

The following table shows sagittal notation accidentals in one apotome for 46edo.

Ups and downs notation

Using Helmholtz–Ellis accidentals, 46edo can also be notated using ups and downs notation:

Step Offset	0	1	2	3	4	5	6	7	8	9	10	11	12
Sharp Symbol
Flat Symbol

Here, a sharp raises by five steps, and a flat lowers by five steps, so single and double arrows can be used to fill in the gap. If the arrows are taken to have their own layer of enharmonic spellings, some notes may be best spelled with three arrows.

• 46et is lower in relative error than any previous equal temperaments in the 17-, 19-, 23-limit, and others. The next equal temperaments doing better in the aforementioned subgroups are 72, 72, 94, respectively. 46et is even more prominent in the no-19 23-limit, and the next equal temperament doing better in this subgroup is 140.
