The '''dimcomp comma''' is a [[small comma|small]] [[7-limit]] [[comma]] measuring about 7.4 [[cent]]s. It is the amount by which a stack of four quasi-tempered minor thirds (([[25/21]])<sup>4</sup>) exceeds an [[2/1|octave]].


The '''dimcomp comma''' is a [[7-limit]] [[small comma]] measuring about 7.4 cents.  
It is also the product of the [[marvel comma]] and the [[landscape comma]].  


It is the amount by which four quasi-tempered minor thirds ([[25/21]]) exceed an octave. Hence, tempering it out splits the octave into four equal parts, and edos that are not multiples of 4 cannot be tempering it out.  
== Temperaments ==
[[Tempering out]] this comma in the 7-limit leads to the [[dimcomp]] temperament, with the effect of splitting the octave into four equal parts, and edos that are not multiples of 4 cannot be tempering it out. Rank-2 temperaments tempering it out include [[diminished (temperament)|diminished]], [[compton]], [[bidia]], [[quadritikleismic]], [[octoid]], etc.  


== See also ==
See [[Dimcomp family]] for a number of rank-3 temperaments where it is tempered out.
