'''Augmented''' is a [[regular temperament|temperament]] that sets [[5/4]] to one third of an [[2/1|octave]], [[tempering out]] the diesis, [[128/125]], and has a [[generator]] of a [[3/2|perfect fifth]]. The fifth can be tuned to [[12edo]], but a sharper tuning is often perferred for it to blend with the sharp 5/4. This gives rise to the natural [[7-limit]] [[extension]] (known as '''augene''') that tempers out [[64/63]] and [[126/125]], where the whole tone stands in for [[8/7]][[~]][[9/8]]. | |||
Further extension to the [[11-limit]] is available by noticing 128/125 = ([[56/55]])⋅([[176/175]]), and tempering out both commas means [[14/11]] is equated to the 1/3 octave as well. This does imply more [[damage]] in the 11-limit however, as the [[11/8]] is now conflated with [[7/5]]. | |||

Augmented is a temperament that sets 5/4 to one third of an octave, tempering out the diesis, 128/125, and has a generator of a perfect fifth. The fifth can be tuned to 12edo, but a sharper tuning is often perferred for it to blend with the sharp 5/4. This gives rise to the natural 7-limit extension (known as augene) that tempers out 64/63 and 126/125, where the whole tone stands in for 8/7~9/8.
Further extension to the 11-limit is available by noticing 128/125 = (56/55)⋅(176/175), and tempering out both commas means 14/11 is equated to the 1/3 octave as well. This does imply more damage in the 11-limit however, as the 11/8 is now conflated with 7/5.
The first few augmented mos scales are 3L 3s, 3L 6s, 3L 9s, 12L 3s, … and the first edos that reasonably support it are 12edo, 15edo, and 27edo.
Alternative 7-limit extensions of augmented include august (9 & 12), which tempers out 36/35 and favors a flat-of-just fifth. Therefore the optimal ET sequence of august goes 9, 12, 21, … in constrast to augmented's which goes 12, 15, 27, ….
See Augmented family #Augmented and #Septimal augmented (augene) for technical data. See Augmented extensions for a discussion on 13-limit extensions.
