'''256/255''', the '''septendecimal kleisma''', '''diasemisma''' or '''255th subharmonic''', is a [[small comma|small]] [[17-limit]] [[superparticular]] comma about 6.8 [[cent]]s in size. It is the difference between [[16/15]] (classical diatonic semitone) and [[17/16]] (large septendecimal semitone, also called as ''minor diatonic semitone''), and forms the amount by which a stack consisting of [[15/8]] and 17/16 falls short of an [[octave]]. It differs from [[352/351]] (the minthma) by [[936/935]] – an [[unnoticeable comma]] measuring about 1.85 cents.

By tempering it out is defined the '''diasemismic temperament''', which enables the [[~~diasemismic~~ chords]].

By tempering it out is defined the '''charismic temperament''' or '''diasemismic temperament''', which enables the [[charismic chords]].

== Etymology ==

The name ''diasemisma'' was named by [[User:Xenllium|Xenllium]] in 2023. It is a contraction of ''diatonic semitone'' into a single word; it is unrelated to the [[diasem]] scale structure. However, ''septendecimal kleisma'' and ''255th subharmonic'' were attested much earlier.

The name ''charisma'' was named by [[User:Godtone|Godtone]] in 2023, and refers to the comma being a superparticular ratio with the numerator is 2^8 (the number of combinations in a byte, often referred to as a char in programming).
