The '''Pythrabian comma''' ({{monzo|legend=1| 33 -23 0 0 -1 }}, [[ratio]]: 94489280512/94143178827) is a [[small comma|small]] [[11-limit]] [[comma]], which measures roughly 6.35 [[cent]]s. It is the interval which, when tempered out, equates [[11/8]] with a stack of twenty-three [[3/2]] perfect fifths octave-reduced, and also equates a stack of two [[Pythagorean comma]]s with [[33/32]]. | |||
The | The name ''Pythrabian comma'' comes from [[11/8]] and 3/2 both being the generators for [[Alpharabian tuning]], with 3/2 additionally being the generator for [[Pythagorean tuning]] – however the name is even more appropriate in light of the aforementioned connection with both the Pythagorean comma and 33/32. | ||
It is tempered out in [[41edo]] and [[53edo]], where 11/8 is mapped to the triply-augmented second (AAA2, e.g. C–D♯𝄪 or C to D triple-sharp). | |||
