The temperament generated by tempering out the frameshift comma.

It still needs to be decided whether this name refers to the higher-rank 11-limit tuning implied by the comma, or whether this name applies to the the rank-2 2.3.11 subgroup tuning implied by the comma.

Whichever it is, the other temperament will have to be given another name that relates to frameshift in some way.

See also the frameshift microtemperaments, various other temperaments that temper the comma.
