4000/3993: Difference between revisions

'''4000/3993''', the '''wizardharry comma''', is an [[unnoticeable comma|unnoticeable]] [[11-limit]] comma with a size of roughly 3.03 [[cents]].  It is the amount by which a stack of three [[11/10]] submajor seconds falls short of the [[4/3]] perfect fourth. Tempering it out means the 4th is divided into an equal stepped tetrachord, however, it does this by means equating a stack of two 11/10 submajor seconds with [[40/33]] rather than by equating a stack of three [[6/5]] intervals with a [[16/9]] interval as in the [[Porcupine]] family of temperaments.
