''Vigintiduo'' has the same 7-limit mapping as 22et with harmonic 11 mapped to an independent generator.
''Vigintiduo'' sets the [[7-limit]] to that of 22edo and harmonic 11 and the rest are independent generators.

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.

22edo is a notable tuning system, and as such it gives rise to some fractional-octave temperaments. This page accommodates a number of temperaments that are otherwise difficult to catalog because they belong to multiple families.

Vigintiduo

Vigintiduo sets the 7-limit to that of 22edo and harmonic 11 and the rest are independent generators.

Subgroup: 2.3.5.7.11

Comma list: 50/49, 64/63, 245/243

Mapping: [⟨22 35 51 62 0], ⟨0 0 0 0 1]]

mapping generators: ~25/24, ~11/8

Optimal tunings:

  • WE: ~25/24 = 54.462 ¢, ~11/8 = 556.713
error map: ⟨-1.830, 4.225, -8.737, 7.836, -0.093]
  • CWE: ~25/24 = 1\22, ~11/8 = 556.295
error map: ⟨0.000 -0.068 -0.088 -0.106 -0.375]

Optimal ET sequence: 22, 66de, 88bde, 110bd, 198bcdde

Badness: 1.599

Vigin

Vigin has the same 11-limit mapping as 22et with harmonic 13 mapped to an independent generator.

Subgroup: 2.3.5.7.11.13

Comma list: 50/49, 55/54, 64/63, 99/98

Mapping: [⟨22 35 51 62 76 0], ⟨0 0 0 0 0 1]]

Optimal tuning (POTE): ~33/32 = 1\22, ~13/8 = 844.624

Optimal ET sequence: 22, 44

Badness: 0.029849

Major arcana

Major arcana is named after a subset of Tarot cards of which there is 22. Tempers out the [-193 154 -22⟩ comma in the 5-limit. Can be conceptualized as a more precise version of icosidillic in the 5-limit and the 7-limit bearing the same pergen (P8/22, P5), however there's no single way to extend it to the 11-limit due to inconsistency.

Subgroup: 2.3.5

Comma list: [-193 154 -22⟩

Mapping: [⟨22 22 -39], ⟨0 1 7]]

mapping generators: ~[79 -63 9⟩, ~3/2

Optimal tuning (CTE): ~3/2 = 701.942

Supporting ETs: 176, 330, 506, 836, 1342, 1848, ...

7-limit

Subgroup: 2.3.5.7

Comma list: 14348907/14336000, [39 11 -11 -11⟩

Mapping: [⟨22 0 -193 271], ⟨0 1 7 -6]]

mapping generators: ~8388608/8103375, ~3/2

Optimal tuning (CTE): ~3/2 = 702.014

Supporting ETs: 176, 506, 682

Titanium

Titanium is named after the 22nd element after the previous temperament called "titanium" was found to be the same thing as beep. It reaches 11/8 and 7/6 in one generator, and as a corollary tempers 96/77 to 7 steps of 22edo.

Subgroup: 2.3.5.7.11

Comma list: 2401/2400, 9801/9800, 2166612408926208/2162550048828125

Mapping: [⟨22 2 10 33 72], ⟨0 8 10 7 1]]

Mapping generators: ~48125/46656 = 1\22, 4296875/3779136 = 224.101

Optimal tuning (CTE): ~4296875/3779136 = 224.101

Supporting ETs: 198, 616, 814, 1012, 1210

13-limit

Subgroup: 2.3.5.7.11.13

Comma list: 2401/2400, 9801/9800, 67392/67375, 142884/142805

Mapping: [⟨22 2 10 33 72 28], ⟨0 8 10 7 1 13]]

Mapping generators: ~65/63 = 1\22, 338/297 = 224.100

Optimal tuning (CTE): ~338/297 = 224.100

Supporting ETs: 198, 616, 814, 1012, 1210
