'''1445/1444''', the '''aureusma''', is a [[19-limit]] (also 2.5.17.19 [[subgroup]]) [[unnoticeable comma]] measuring about 1.20 [[cent]]s. It is the difference between [[5/4]] and a stack of two [[19/17]]'s. It is also the difference between [[153/152]] and [[171/170]]. | |||
== Commatic relations == | |||
This comma is the difference between the following superparticular pairs: | |||
* [[153/152]] and [[171/170]] | |||
* [[1156/1155]] and [[5776/5775]] | |||
* [[1275/1274]] and [[10830/10829]] | |||
It factors into the following superparticular pairs: | |||
* [[2601/2600]] and [[3250/3249]] | |||
* [[1540/1539]] and [[23409/23408]] | |||
* [[1521/1520]] and [[28900/28899]] | |||
== Temperaments == | |||
Tempering out this comma in the 19-limit leads to the rank-7 '''aureusmic temperament''', or in the 2.5.17.19 subgroup, the rank-3 '''aureus temperament'''. In either case it results in 5/4 being split into two 19/17's, and enables the essentially tempered [[aureusmic chords]]. | |||
== Etymology == | |||
The aureusma was named by [[Flora Canou]] in 2021. It comes from Latin ''[[Wiktionary: aureus #Latin|aureus]]'' ("golden"), for its possible association with [[golden meantone]]. | |||
