'''2080/2079''', the '''ibnsinma''', is a [[13-limit]] [[~~unnoticeable~~ comma]] measuring about 0.83 [[cent]]s. It is the amount by which a stack consisting of [[11/10]] and [[14/13]] falls short of Pythagorean minor third, [[32/27]].

~~By tempering it~~ out ~~is defined~~ the '''ibnsinmic ~~temperament~~''', which enables the [[ibnsinmic chords]], the essentially tempered ~~chords~~ in the 21-odd-limit. Another consequence is that it makes ~~[[fifth complement]]s of~~ [[13/11]] and [[80/63]], ~~and of~~ [[40/33]] and [[26/21]]. You may find a list of good equal ~~temperaments~~ that support this temperament below.

~~The ibnsinma~~ was named by [[Margo Schulter]] in 2012, when it went by ''ibn Sina's comma''<ref>[https://yahootuninggroupsultimatebackup.github.io/tuning/topicId_105620.html Yahoo! Tuning List | ''123201/123200 chalmersia, 194481/194480 scintillisma'']</ref>. It was contracted to ''avicennma'' and later changed to ''ibnsinma'', all essentially meaning the same ~~thing, but note~~ that ''avicennma'' refers to Avicenna's enharmonic diesis ([[525/512]]) today.
