The ''aurora'' temperament ({{nowrap| 13 & 21 }}) is very strongly related to the [[Logarithmic phi|golden oneirotonic tuning]] (generator: {{nowrap| (3 - sqrt(5))/2 }} octave = 458.3592135001 cents). It has a temperament structure superficially similar to [[father]], with extremely flat fourths (sub-fourths/ultra-major third) or sharp fifths (super-fifths/ultra-minor sixths). However, unlike father, 12 of these bad fourths reach a more in tune fifth, which is useful for creating resolutions when using a large enough gamut, such as the [[13L 8s]] mos which has two good major & minor chords.

This is a list showing technical temperament data. For an explanation of what information is shown here, you may look at the technical data guide for regular temperaments.

This is a collection of rank-2 keegic temperaments, which temper out the keega (ratio: 1029/1000, monzo: [-3 1 -3 3⟩), the difference a stack of three 10/7's and the 3rd harmonic.

Temperaments discussed elsewhere include antitonic, kangaroo, keemun, liese, progress, subklei, triton, trisected, and xenia.

Quinkee

Quinkee has a period of 1/5 octave and tempers out the keega (1029/1000), from which it derives its name. It may be described as the 15 & 55 temperament. It was named by Xenllium in 2021.

Aurora

For the 5-limit version, see Diaschismic–gothmic equivalence continuum #Goldis.

The aurora temperament (13 & 21) is very strongly related to the golden oneirotonic tuning (generator: (3 - sqrt(5))/2 octave = 458.3592135001 cents). It has a temperament structure superficially similar to father, with extremely flat fourths (subfourths/ultramajor third) or sharp fifths (superfifths/ultraminor sixths). However, unlike father, 12 of these bad fourths reach a more in-tune fifth, which is useful for creating resolutions when using a large enough gamut, such as the 13L 8s mos which has two good major & minor chords.
