The '''antimisma''', 1617/1600, is the amount by which [[11/10]] exceeds [[160/147]]. It is the difference between the ptolemisma ([[100/99]]) and the septimal diesis ([[49/48]]), making it an anti-ptolemisma, or anti-misma. However, that is not the origin of the name. In fact, it is named after [https://en.wikipedia.org/wiki/Antimo_Liberati Antimo Liberati], because his birth year of 1617 is the numerator of this comma. | The '''antimisma''', '''1617/1600''', is the amount by which [[11/10]] exceeds [[160/147]].

A stack of two septimal tritones ([[7/5]]) and an undecimal superfourth ([[11/8]]) is an antimisma above a perfect eleventh ([[8/3]]). While this leads to an essentially tempered chord of 1/1-7/5-49/25-8/3, it's rather far-flung. | A stack of two septimal tritones ([[7/5]]) and an undecimal superfourth ([[11/8]]) is an antimisma above a perfect eleventh ([[8/3]]).
