In [[31-limit]] [[just intonation]], '''31/24''' is either the '''tricesimoprimal ultramajor third''' or '''tricesimoprimal subfourth'''. It is sharp of the [[81/64|Pythagorean major third (81/64)]] by [[248/243]], and flat of the [[4/3|perfect fourth (4/3)]] by [[32/31]]. It can be used as a [[generator]] tuning for the [[sensi]] temperament, and more accurate interpretations of the extended harmony of the [[5-limit]] [[sensipent]] temperament. In this context, it is equated to its complement relative to [[5/3]], that is, [[40/31]].

~~'''31/24'''~~, ~~the '''sensi~~ supermajor third~~'''~~, ~~can be used as a generator tuning for~~ [[~~Sensipent family#Sensi|sensi temperament~~]], ~~especially~~ for ~~the~~ [[~~5-limit~~]] ~~sensipent temperament~~. It is ~~very~~ close to ~~the 24\~~[[65edo|65]] ~~generator~~.

In general, it can serve as an alternative sharp [[major third (interval region)|supermajor third]] to [[9/7]], which is flat of it by [[217/216]], for greater flexibility in [[otonal]] chords containing intervals that do not have a 7 in their denominator.

== Approximation ==

31/24 is approximated by [[19edo|7\19]], and is extremely close to [[65edo|24\65]] (being just 0.0036{{c}} sharp of it).
