'''140/81''', the '''septimal inframinor seventh''' is a [[7-limit]] [[interseptimal]] ratio of about 947 [[cent]]s. It is flat of a minor seventh [[16/9]] by a septimal quartertone [[36/35]], flat of a subminor seventh [[7/4]] by a syntonic comma [[81/80]], and sharp of a supermajor sixth [[12/7]] by a sensamagic comma [[245/243]]. | '''140/81''', the '''septimal inframinor seventh''' is a [[7-limit]] [[interseptimal]] ratio of about 947 [[cent]]s.

Notice it is also sharp of the just major sixth [[5/3]] by a subminor second [[28/27]]. For this fact it is useful in the [[sensamagic dominant chord]] where it functions as a dissonance yet to be resolved down to the major sixth.

The [[Cathartic family|cathartic temperament]] targets this progression and uses it as one of the generators. | ||
