Approximating JI with temperaments: add this

			== Approximating JI with temperaments ==
			{{Main\|Temperament}}
			There are a lot of JI intervals, and it's difficult to keep track of all of them. As such, people often use simpler systems to approximate JI intervals, known as [[temperament]]s. A popular choice is [[equal temperament]]s; for example the predominant [[12edo\|12et]], which is widely used to approximate [[5-limit]] JI. Other equal temperaments exist, for example [[19edo\|19et]], [[22edo\|22et]], and [[31edo\|31et]]. Besides equal temperaments, other temperaments exist, such as [[regular temperament]]s and [[well temperament]]s.

			Temperaments also create new structures not found in JI; for example, [[meantone]] temperament (which 12et [[support]]s) tempers out the syntonic comma [[81/80]], making [[5/4]] the same as the major third obtained by stacking four fifths, [[81/64]]; this structural feature is often assumed without thinking in western music. There are many temperaments in various limits, including the 5-limit, the [[7-limit]], and beyond, as well as many subgroups.

			[[Microtemperaments]] are very accurate and temper out [[unnoticeable comma]]s, and add minimal damage to the intervals of JI, while also simplifying its structure. For example, [[schismic]] flattens the fifth by around 0.2 cents to equate the [[Pythagorean comma]] with the syntonic comma. Microtemperaments are also very useful in higher prime limits, where JI itself becomes too complex.

	=== 53edo (demonstrated to work) ===		=== 53edo (2 mappings demonstrated to work) ===

	[[Bryan Deister]] has demonstrated ~~a mapping~~ for [[53edo]] ~~in [https://www.youtube.com/shorts/WtSaDQCyfVc ''Waltz in 53edo''] (2026)~~ that functions for [[Kleismic_family#Hemikleismic\|hemikleismic]] ([[7L 1s]] scale with a 7:4 step ratio ~~right and right-up~~ with the small step stretched) and [[~~Porwell_temperaments~~#Semaja\|semaja]] (rotated [[5L 1s]] with a 10:3 step ratio down-right and down); a [[5L 8s (4/1-equivalent)]] scale with a 10:7 step ratio is also available moving right and down-right. The range is a bit over 4⅓ octaves, with no missed notes and just one repeated note in each octave, but the upper left and lower right corners have many additional non-contiguous notes, and the octaves are not in consistent places; on the other hand, classic thirds both minor (two steps right) and major (one step right plus one step down-right) are in very easy reach as long as they do not pass through a vertical wraparound (it may be necessary to adjust note 0 position to avoid this for a particular performance, such as in the linked video which has note 0 where note 3 is here).		[[Bryan Deister]] has demonstrated two mappings for [[53edo]] that functions for [[Kleismic_family#Hemikleismic\|hemikleismic]] ([[7L 1s]] (pine) scale with a 7:4 step ratio with the small step stretched) and [[Gariboh_clan#Semaja\|semaja]] (rotated [[5L 1s]] scale with a 10:3 step ratio); both versions favor hemikleismic over semaja. For hemikleismic, the generator 7\53 is half of a near-just classic minor third ~[[6/5]], which functions as a flat undecimal submajor second ~[[11/10]], a sharp undecimal neutral second ~[[12/11]], a slightly sharp septimal neutral second ~[[35/32]], and a near-just large vicesimotertial neutral second ~[[23/21]]. Four of these make a slightly flat tridecimal diminished fifth ~[[13/9]]; five of them make a somewhat flat Boethius' minor sixth ~[[12/9]]; after octave-reduction, ten of them make a flat flat septimal major second ~[[8/7]], which at 10\53 is the generator for semaja; several undevicesimal ratios are also available. Two of the semaja generator make a slightly flat Barbados third ~[[13/10]]; after octave-reduction, eight of them make a near-just classic major third ~[[5/4]]; several tridecimal ratios are also available.

			==== Reverse chroma ====

			In the reverse-chroma version demonstrated in [https://www.youtube.com/shorts/WtSaDQCyfVc ''Waltz in 53edo''] (2026), the hemikleismic 7L 1s scale is played by moving right and right-up with the small step stretched, and the semaja rotated [[5L 1s]] scale is played by moving down-right and down; a [[5L 8s (4/1-equivalent)]] scale with a 10:7 step ratio is also available moving right and down-right. The range is a bit over 4⅓ octaves, with no missed notes and just one repeated note in each octave, but the upper left and lower right corners have many additional non-contiguous notes, and the octaves are not in consistent places; on the other hand, classic thirds both minor (two steps right) and major (one step right plus one step down-right) are in very easy reach as long as they do not pass through a vertical wraparound (it may be necessary to adjust note 0 position to avoid this for a particular performance, such as in the linked video which has note 0 where note 3 is here).

			==== Forward oversize chroma ====

			In the forward oversize chroma version (very similar to the [[Lumatone_mapping_for_porcupine#Expanded\|expanded Lumatone mapping for porcupine]]), demonstrated in [https://www.youtube.com/shorts/7YfZZ7aMvH8 ''53edo groove''] (2026), the hemikleismic 7L 1s scale is played by moving right and right-down-right with the small step stretched, and the semaja rotated [[5L 1s]] scale is played by moving up and up-left; the 5L 8s (4/1-equivalent) scale is not practical in this version. The range is less than that of the reverse chroma version, at somewhat under three complete octaves, but in exchange, more repeated notes are available to mitigate vertical wraparounds, and the upwards slope of the octaves is less.

			:: If you agree a subgroup extension is canonical s.t there's no ambiguity (meaning it's unique among alternatives) then I believe it should be presented as such (as an extension proper, but with a subheader indicating it's a subgroup extension, as it was before). Furthermore, your reason seems backwards to me; shouldn't a subgroup extension that isn't in the increasing order of primes be prioritised at the very top, as it represents unique information? --[[User:Godtone\|Godtone]] ([[User talk:Godtone\|talk]])

			=== A general Skirmish ===
			Any scale of this form for any cent value 0 < C < 4/3. I declare to be a Skirmish. RH Skirmish have sqrt(4/3) < C < 4/3, and LH 1 < C < sqrt(4/3). This also means that the above scales, Nicepent, Pyth pentic modes, and semiquartal scales are Skirmishes, though... the term is better for C ≈ 13/12, you know, "minor second-ish" intervals.

			Chlorine (named after the 17th element) tempers out the [[septendecima]] in the 5-limit, and {{monzo\| -49 4 22 -3 }} as well as the ragisma in the 7-limit. It has a 1/17-octave period, and can be described as {{nowrap\| 289 & 323 }} temperament. Not only the semitwelfth, but also the ~5/4 can be used as a generator.
