-A [[19-limit]] comma splitting [[5/4]] into a [[19/17]] half.
+'''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 ==
-[[Category:Superparticular]]
+This comma is the difference between the following superparticular pairs:
-[[Category:Unnoticeable comma]]
+* [[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]].
