Temperaments
Tempering out this comma leads to the greenwoodmic temperament. See Greenwoodmic temperaments for a collection of rank-2 temperaments where it is tempered out.
Notation
Sagittal notation
In the Sagittal system, the downward version of this comma (possibly tempered) is represented by the sagittal and is called the 49/5 medium diesis, or 49/5M for short, because the simplest interval it notates is 49/5 = 7×7/5 (equiv. 49/40), as for example in C-E . The upward version is called 5/49M or 49/5M up and is represented by .
