The '''semicanousma''', 14641/14580 = {{monzo|-2 -6 -1 0 4}}, is a [[11-limit]] [[comma]] measuring about 7.2 ~~cents~~, named for it is one of the commas tempered out in [[~~Canou family #Semicanou|~~semicanou temperament]]. It is the difference between [[121/120]] (biyatisma) and [[243/242]] (rastma).

The '''semicanousma''', 14641/14580 = {{monzo| -2 -6 -1 0 4 }}, is an [[11-limit]] [[comma]] measuring about 7.2 [[cent]]s, named for the fact that it is one of the commas tempered out in the [[semicanou]] temperament. It is the amount by which a stack of four [[11/9|Alpharabian artoneutral thirds (11/9)]] exceeds the [[20/9|ptolemaic ninth (20/9)]]. It is also the difference between [[121/120]] (biyatisma) and [[243/242]] (rastma).

Tempering it out leads to the rank-4 ~~[[semicanousmic temperaments|~~semicanousmic temperament]], which splits the [[81/80|syntonic comma]] into two equal parts, each representing 121/120~243/242, so it can be said to be the undecimal counterpart of both [[3136/3125|hemimean]] and [[canousma]]. 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]].

Tempering it out leads to the rank-4 '''semicanousmic 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 [[canousma]]. 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]].
