'''2058/2057''', the '''xenisma''', is an [[unnoticeable comma|unnoticeable]] [[17-limit]] (also 2.3.7.11.17 [[subgroup]]) [[comma]] measuring about 0.84 [[cent]]s. It is the amount by which a stack of two [[14/11]]'s exceed [[34/21]], or equivalently the amount by which 49/44 (2.7.11 minor tone) * 14/11 exceeds [[17/12]]
'''2058/2057''', the '''xenisma''', is an [[unnoticeable comma|unnoticeable]] [[17-limit]] (also 2.3.7.11.17-[[subgroup]]) [[comma]] measuring about 0.841 [[cent]]s. It is the amount by which a stack of two [[14/11]]'s exceed [[34/21]], or equivalently the amount by which a stack consisting of [[49/44]] and 14/11 exceeds [[17/12]].

Tempering out this comma in the 17-limit results in the rank-6 '''xenismic temperament''', or in the 2.3.7.11.17 subgroup, the rank-4 '''xenic temperament'''. In either case it enables [[xenismic chords]].

The xenisma was named by [[Margo Schulter]] in 2000<ref>[https://yahootuninggroupsultimatebackup.github.io/tuning/topicId_12989.html Yahoo! Tuning Group | ''Re: Kalisma/xenisma (new names?) -- JI tuning and Scala file'']</ref>.  
This comma was named by [[Margo Schulter]] in 2000<ref>[https://yahootuninggroupsultimatebackup.github.io/tuning/topicId_12989.html Yahoo! Tuning Group | ''Re: Kalisma/xenisma (new names?) -- JI tuning and Scala file'']</ref>. Its name comes from the Ancient Greek word [[wiktionary: ξένος #Ancient Greek|''xénos'']] ("strange"), which may suggest the strange and wonderful qualities in a [[neogothic]] setting of supraminor and submajor thirds.
