The '''7-39-comma''' ([[monzo]]: 2.3.13 {{monzo| 37 -7 -7 }}, ratio: 137 438 953 472 / 137 231 006 679) is a [[unnoticeable comma|unnoticeable]] [[13-limit]] [[comma]] of about 2.62 [[cent]]s. It is the amount by which a stack of seven [[39/32]]'s fall short of two octaves. It is tempered out in low edos that are a multiple of 7, which approximate 39/32 within a fraction of a cent. In [[L4MPLIGHT#Shasavistic music theory|Shasavistic theory]], it is called ''Safusagnama''.

It factors into [[816293376/815730721]] and the [[tridecapyth comma]], and is also equal to seven [[minisma]]s minus the [[akjaysma]]. Thus, tempering out any of those pairs of commas implies also tempering this out.
