Orthoschismic is related to [[schismic]], but with an additional generator for [[prime interval|prime]] [[7/1|7]], extended to the 11-limit in one of the most efficient ways possible. | |||
Orthoschismic can be notated with [[chain-of-fifths notation]] with two additional set of accidentals, one for the generic comma step (one should choose whether this step represents the syntonic comma, which is more characteristic in schismic, or the septimal comma, which is more characteristic in [[olympic]]), and the other for the generic aberschisma step which stands in for the [[garischisma]] and the [[aberschisma]]. | |||
It was named by [[Flora Canou]] in 2023, using the Greek prefix [[wiktionary: ortho- #English|ortho-]] to signify the additional rank. | |||

Baffin tempers out [[5632/5625]] and [[160083/160000]] in addition to the olympia, so that the [[3/1|3rd]] [[harmonic]] is split in halves. This leads naturally to a [[13-limit]] temperament where [[676/675]], [[1001/1000]], [[2080/2079]] and [[4096/4095]] are all tempered out. | |||

- This is a list showing technical temperament data. For an explanation of what information is shown here, you may look at the technical data guide for regular temperaments.
The olympic clan of rank-3 temperaments tempers out the olympia (ratio: 131072/130977, monzo: [17 -5 0 -2 -1⟩). This has the effect of equating the undecimal quartertone (33/32) with a stack of two septimal commas (64/63).
For the rank-4 olympic temperament, see Rank-4 temperament #Olympic (131072/130977).

Overview to extensions
The second comma in the comma list determines how we extend olympian to include the harmonic 5. Akea adds 385/384, and finds the harmonic 5 by equating the syntonic comma (81/80) with the septimal comma. Orthoschismic adds 32805/32768, and finds the harmonic 5 on the chain of fifths. Cassaschismic adds 19712/19683 with an independent generator for harmonic 5. Pessoal adds 9801/9800, splitting the octave into two. Lif adds 2401/2400, splitting the perfect fifth into two. Baffin adds 5632/5625, splitting the perfect twelfth into two. Lux adds 3025/3024, splitting the ~21/16 into two. Hera adds 6144/6125 or 8019/8000, splitting the ~21/16 into three. Finally, sophia adds 42875/42768, splitting the ~8/7 into three. These all have neat extensions to the 13-limit via tempering out both 2080/2079 and 4096/4095.
Temperaments discussed elsewhere are:
- Akea (+385/384) → Hemifamity family
- Cassaschismic (+19712/19683) → Garischismic family
- Pessoal (+9801/9800) → Kalismic temperaments
- Lif (+2401/2400) → Breed family
- Lux (+3025/3024) → Lehmerismic temperaments
- Hera (+6144/6125) → Porwell family
Considered below are orthoschismic, baffin and sophia.
Orthoschismic
Orthoschismic is related to schismic, but with an additional generator for prime 7, extended to the 11-limit in one of the most efficient ways possible.
Orthoschismic can be notated with chain-of-fifths notation with two additional set of accidentals, one for the generic comma step (one should choose whether this step represents the syntonic comma, which is more characteristic in schismic, or the septimal comma, which is more characteristic in olympic), and the other for the generic aberschisma step which stands in for the garischisma and the aberschisma.
It was named by Flora Canou in 2023, using the Greek prefix ortho- to signify the additional rank.

Baffin
- For the 7-limit version, see Miscellaneous 7-limit temperaments #Decovulture.
Baffin tempers out 5632/5625 and 160083/160000 in addition to the olympia, so that the 3rd harmonic is split in halves. This leads naturally to a 13-limit temperament where 676/675, 1001/1000, 2080/2079 and 4096/4095 are all tempered out.
It was named by Gene Ward Smith some time before 2011 for Baffin Island, as part of a series of island-themed names[1].
