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]]. | |||

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]]. | |||
