'''Zeus''' is ~~the~~ [[rank-3 temperament]] tempering out [[121/120]], [[176/175]], and [[385/384]]. Notice 121/120 = (176/175)(385/384)~~, it thus equates the septimal neutral second of [[35/32]] with both [[11/10]] and [[12/11]]~~. That makes 11-limit harmony particularly efficient and deeply entangled with 7-limit harmony. ~~The~~ temperament is, in fact, one of the best ways to further temper on top of tempering out 121/120. That said, 121/120 is such a comma that, on tempering out, will neutralize the distinction between many otonal- and utonal-11 chords, so it might not fit those who wish to explore the subtlety of tones in the 11-limit.

~~See~~ [[~~Porwell family #Zeus~~]] or [[Biyatismic clan #Zeus]] for technical data.

It also has an obvious extension to the 13-limit tempering out [[351/350]] and [[352/351]].
