== Metric == | |||
Metric tempers out the [[meter]], and splits the [[syntonic comma]] into three equal parts, one for the marvel comma, [[225/224]], and two for the starling comma, [[126/125]]. It is therefore [[support]]ed by third-comma equal temperaments, and [[171edo]] shows an excellent example of this. 11-limit extensions of this temperament include [[Moctdelismic clan #Mendel|mendel]] and [[Lehmerismic temperaments #Skadi|skadi]]. | |||

== Greenwoodmic == | |||
Greenwoodmic tempers out the [[greenwoodma]] in the 7-limit. It equates [[5/2]] with a stack of two [[14/9]]'s. This implies [[prime interval|primes]] [[3/1|3]] and [[5/1|5]] should be tuned flat, and [[7/1|7]] should be tuned sharp. A rank-2 temperament that does that is [[injera]], which introduces little extra [[damage]] over greenwoodmic. | |||
In contrast to [[sensamagic]], where two [[9/7]]'s stack to [[5/3]], here two 9/7's stack to [[8/5]]. As such, greenwoodmic induces [[essentially tempered chord]]s in the [[9-odd-limit]]. An obvious 11-limit extension then equates [[5/4]] with [[11/9]] and equates 9/7 with [[14/11]], tempering out [[45/44]] as well as [[99/98]] using the identity 405/392 = (45/44)⋅(99/98). | |||

== Avicennmic == | |||
Avicennmic tempers out the [[avicennma]] in the 7-limit. It equates [[32/21]] with a stack of two [[5/4]]'s, and [[12/7]] with a stack of two [[15/8]]'s octave reduced. This implies [[prime interval|primes]] [[3/1|3]], [[5/1|5]] and [[7/1|7]] should all be tuned flat. A rank-2 temperament that does that is [[flattone]], which introduces little extra [[damage]] over avicennmic. | |||
One possible extension of avicennmic to the 11-limit is via [[45/44]] and [[385/384]], using the identity 525/512 = (45/44)⋅(385/384), but the result is somewhat less accurate. Instead, it is more natural to extend it to the [[2.3.5.7.13 subgroup]] by tempering out [[65/64]] and [[105/104]], using the identity 525/512 = (65/64)⋅(105/104). | |||

Quasiorwellismic tempers out the [[quasiorwellisma]] in the 7-limit, and finds [[7/6]] by a stack of ten [[5/4]]'s octave reduced. A natural 11-limit extension thus arises from mapping [[11/9]] to a stack of four [[5/4]]'s octave reduced, leading to [[ganesha]], which tempers out [[3025/3024]] and [[5632/5625]]. | |||

Parahemif tempers out the [[parahemif comma]] in the 7-limit, equating a [[Pythagorean apotome]] with a stack of two septimal third-tones of [[28/27]], and splits the fifth in two. It also equates the large septimal diesis of [[49/48]] with the [[Pythagorean comma]]. This means the fifth should be tuned sharp and the septimal third-tone should be flattened to a somewhat large quartertone which can be used as the undecimal quartertone of [[33/32]], leading to a natural 11-limit extension where [[243/242]] and [[896/891]] are tempered out. | |||
