			The '''semicathartisma''' (formerly ''semicanousma'', {{monzo\|legend=1\| -2 -6 -1 0 4 }}, [[ratio]]: 14641/14580) is a [[small comma\|small]] [[11-limit]] [[comma]] measuring about 7.23 [[cent]]s. It is the amount by which a stack of four [[11/9\|Alpharabian artoneutral thirds (11/9)]] exceeds the [[20/9\|ptolemaic major ninth (20/9)]]. It is also the difference between [[121/120]] (biyatisma) and [[243/242]] (rastma).

			[[Tempering out]] this comma in the 11-limit leads to the rank-4 [[semicathartismic]] temperament, which splits the [[81/80\|syntonic comma]] into two equal parts, each representing 121/120~243/242, so the comma can be said to be the undecimal counterpart of both [[3136/3125\|hemimean]] and [[cathartic comma]]. It also identifies [[20/11]] by three [[11/9]]'s stacked, so an octave is divided into 11/9–11/9–11/9–[[11/10]].

	~~== Temperaments ==~~		See [[Semicathartismic clan]] for the clan of rank-3 temperaments where it is tempered out.

	* [[Rank-4 temperament #Semicanousmic (14641/14580)]]		This comma was first named by [[Flora Canou]] as ''semicanousma'' in 2020, for the fact that it is one of the commas tempered out in the semicanou (now [[semicathart]]) temperament. In 2026, she disavowed that name and came up with the current name as a replacement, following the rename of ''semicanou'' to ''semicathart''.
