The archangelic comma (monzo: [301994 -190537⟩) is the amount by which 190537 perfect fifths fall short of 111457 octaves, in other words 2111457/(3/2)190537. This difference is inaudible at roughly 0.0001 cents.
This comma was named by Aura in direct opposition to the satanic comma due to it being the first 3-limit comma to have a 3-2 telicity k-strength greater than 1 in the 3/2 convergence series after the satanic comma, and, due to actually surpassing the satanic comma in 3-2 telicity k-strength.
Temperament
Tempering out this comma leads to the Archangelic family of temperaments. It is tempered out in 190537edo and its multiples.
