'''109-7-comma''' is the interval which represents a closed circle of 109 [[7/1|7th harmonics]] with 306 octaves, or alternately, 109 [[7/4]] septimal minor sevenths with the octave. It is notable because of [[109edo]] being a denominator to [[semiconvergent]] for log<sub>2</sub>7. | '''109-7-comma''' is the interval which represents a closed circle of 109 [[7/1|7th harmonics]] with 306 octaves, or alternately, 109 [[7/4]] septimal minor sevenths with the octave.

Tempering it out maps [[7/4]] into 88\109, that is 88 steps of 109edo. Aside from 109edo, it is tempered out by high-limit systems such as [[436edo]] and [[981edo]]. | Tempering it out maps [[7/4]] into 88\109, that is 88 steps of 109edo.
