'''1287/1280''', the '''catadictma''', is a [[13-limit]] [[small comma]]. It is the amount by which a stack consisting of [[16/11]] and [[16/13]] falls short of [[9/5]], or the comma that, when tempered out, has [[4/3]] equidistant between [[13/10]] and [[11/8]]. It can be factored into simpler commas as ([[351/350]])([[385/384]]), or as ([[225/224]])([[1001/1000]]). In terms of superparticulars, it is ([[33/32]])/([[40/39]]). By tempering it out is defined the '''catadictmic temperament''', which enables the [[catadictmic chords]]. Adding [[676/675]] lets you efficiently incorporate 11-limit harmony into [[barbados]] chords. | '''1287/1280''', the '''catadictma''', is a [[13-limit]] [[small comma]].
