'''5120/5103''', the '''aberschisma''' (formerly ''hemifamity comma''), is a [[small comma|small]] [[7-limit]] [[comma]] measuring about 5.76 [[cent]]s. It is the difference between [[7/5]] (small septimal tritone) and [[1024/729]] (Pythagorean diminished fifth), or between [[10/7]] (large septimal tritone) and [[729/512]] (Pythagorean augmented fourth). It is also the difference between [[15/14]] and [[2187/2048]], between [[21/20]] and [[256/243]], between [[80/63]] and [[81/64]], etc., hence, between the septimal comma of [[64/63]] and the syntonic comma of [[81/80]], ~~as well as~~ between [[~~225/224~~]], the ~~marvel comma, and~~ [[32805/32768]], the schisma.

In terms of smaller commas, it is the difference between the [[marvel comma]] and the [[32805/32768|schisma]], as well as the sum of the schisma and the [[septischisma]].
