The [[generator]] for the gravity temperament is a grave fifth of [[~]][[40/27]], and hence the name. However, the functional generator is the acute fourth of ~[[27/20]], six of which reach the [[6/1|6th harmonic]]; ~~its~~ [[ploidacot]] is beta-hexacot. It is part of the [[syntonic–chromatic equivalence continuum]] with {{nowrap| ''n'' {{=}} 6 }}, so it equates a [[2187/2048|Pythagorean apotome]] with a stack of six [[81/80|syntonic commas]].
