The '''chrysia''' (~~[[monzo]]:~~ {{monzo| -7 1 0 -3 4 }}, [[ratio]]: 43923/43904) is an [[unnoticeable comma|unnoticeable]] [[11-limit]] (also 2.3.7.11 [[subgroup]]) [[comma]] measuring about 0.749 [[cent]]s. It is the amount by which three intervals of [[11/7]] and [[33/32]] exceed two octaves.

== Temperaments ==

Alongside the [[olympia]] (131072/130977) and [[41503/41472|argyria]] (41503/41472), this comma is tempered in the representation of 2.3.7.11 by [[135edo]]. Among the various 2.3.7.11 micro-commas of 135edo, this comma is notable for having only a single power of 3 in it, allowing 3 to be represented by 2.7.11 subgroup intervals. One notable example is given by [[No-fives subgroup temperaments #Chrysanthemum|chrysanthemum]] temperament, which tempers the chrysia alongside the [[amaranthinisma]] to provide a 2.3.7.11 interpretation of a chain of nearly pure [[7/4]]s with errors less than 0.1 cents.

== Etymology ==

The chrysia was named by [[User:VIxen|VIxen]] in 2025, on the pattern of the [[argyria]], after Chryse Planitia on Mars and the legendary island of Chryse.

It was previously named the "hemigail comma" by an unknown wiki contributor some time before 2025 (the name appeared on the page [[~~unnoticeable~~ commas]]).
