The '''archangelic comma''' ([[monzo]]: {{monzo| 301994 -190537 }}) is the amount by which 190537 [[perfect fifth]]s fall short of 111457 [[octave]]s, in other words 2<sup>111457</sup>/(3/2)<sup>190537</sup>.  This difference is inaudible at roughly 0.0001 [[cents]].

This comma was named by [[User:Aura|Aura]] in direct opposition to the [[satanic comma]] due to [[190537edo]] actually surpassing [[665edo]] in 3-2 telicity k-strength.  However, it is opposite the satanic comma in other ways, such as the fact that tempering this comma results in a stretched fifth rather than a compressed fifth.

Tempering out this comma leads to the [[archangelic family]] of temperaments.  It is tempered out in 190537edo and its multiples ([[571611edo]], [[762148edo]], [[1714833edo]], [[1905370edo]], and [[4191814edo]] just to name a few), with 190537edo itself being a 28-strong 3-2 telic system due to tempering this comma out.
