'''~~Counterquectisma~~''', alternatively known as the '''deltapion comma''', is an [[unnoticeable comma|unnoticeable]] [[5-limit]] [[comma]].

The '''counterquectisma''', alternatively known as the '''deltapion comma''', is an [[unnoticeable comma|unnoticeable]] [[5-limit]] [[comma]].

== Temperaments ==

It is associated with systems which have a precise perfect fifth, such as [[359edo]] and [[665edo]]. Tempering it out in the 5-limit produces rank-2 ~~'''counterquectismic''' temperament (→~~ [[~~Very high accuracy temperaments #Counterquectismic~~]]). Equal tempereaments tempering out this comma include {{EDOs| 359, 665, 1024, 1689, 3684, 4349, 7368, 8033 }} among others.

== Etymology ==

The comma was named by [[Eliora]]~~. First name derives from comma's monzo, number 500 being D in roman numerals, and phonetic alphabet for D is "delta", to which "pi" is added to signify 314, the decimal expansion of pi~~. The ~~second~~ name is by analogy with [[quectisma]], meaning that both are the same commas that reach [[5/4]] from a different angle, with two mappings converging from opposite ends in [[665edo]].
