Not to be confused with Syntonic comma.

The syntonoschisma or syntonic schisma is an unnoticeable 11-limit comma with a value of approximately 0.093 cents. The syntonoschisma is significant on account of it being the interval between a stack of seven syntonic commas and one 12/11 neutral second in just intonation – this significance in relation to syntonic comma being the source of its name.

Tempering out this comma in the full 11-limit leads to a form of syntonoschismic temperament, or in the 2.3.5.11 subgroup, a syntonoschic temperament.

The comma's name was originally proposed by Xenllium as syntonisma, but as that was a systematically derived name for the syntonic comma itself, it was soon changed to syntonoschisma.
