| Interval information |
The immunity comma (monzo: [16 -13 2⟩, ratio: 1638400/1594323) is a medium 5-limit comma of about 47.2 cents. It is the difference between the Pythagorean diatonic semitone (256/243) and a stack of two syntonic commas.
Temperaments
Tempering out this comma leads to the immunity family of temperaments. These temperaments offer hemifourths and hemitwelfths as a result of dividing the diatonic semitone in equal halves.
Etymology
This comma was named by Mike Battaglia in 2011 such that the corresponding temperament is paired with amity[1][2].
Perhaps "Immunity," because it's a counterpart to Amity or something like that.
