== Orwellismic ==
Orwellismic uses three [[~]][[7/6]] generators to reach [[8/5]] while preserving the lattice structure of the [[2.3.7 subgroup]]. Ideally, 7/6 and 5/4 are both tuned slightly sharp.

Guanyin is the most natural [[11-limit]] extension of orwellismic, where two ~7/6 generators make [[15/11]], tempering out [[540/539]], and two sharpened ~[[5/4]]'s make [[11/7]], tempering out [[176/175]].

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 orwellismic family of rank-3 temperaments tempers out the orwellisma, 1728/1715.

Orwellismic

Orwellismic uses three ~7/6 generators to reach 8/5 while preserving the lattice structure of the 2.3.7 subgroup. Ideally, 7/6 and 5/4 are both tuned slightly sharp.

Subgroup: 2.3.5.7

Comma list: 1728/1715

Mapping: [⟨1 0 0 2], ⟨0 1 0 1], ⟨0 0 3 -1]]

mapping generators: ~2, ~3, ~12/7

Mapping to lattice: [⟨0 0 -3 1], ⟨0 1 0 1]]

Lattice basis:

7/6 length = 0.7526, 3/2 length = 1.3931
Angle (7/6, 3/2) = 97.5081

Optimal tunings:

  • WE: ~2 = 1199.4176 ¢, ~3/2 = 701.8055 ¢, ~12/7 = 928.9445 ¢
error map: ⟨-0.582 -0.732 +0.520 +2.288]
  • CWE: ~2 = 1200.0000 ¢, ~3/2 = 701.6429 ¢, ~12/7 = 929.2316 ¢
error map: ⟨0.000 -0.312 +1.381 +3.585]

Minimax tuning:

[[1 0 0 0⟩, [0 1 0 0⟩, [3/2 3/4 3/4 -3/4⟩, [3/2 3/4 -1/4 1/4⟩]
unchanged-interval (eigenmonzo) basis: 2.3.7/5

Optimal ET sequence: 4, 5, 9, 17, 18, 22, 27, 31, 53, 80, 84, 111, 164d, 195d, 275d, 306d

Badness (Sintel): 0.826

Projection pair: ~5 = 1728/343 to 2.3.7

Scales: orwellismic9, orwellismic diatonic

Guanyin

Guanyin is the most natural 11-limit extension of orwellismic, where two ~7/6 generators make 15/11, tempering out 540/539, and two sharpened ~5/4's make 11/7, tempering out 176/175.

Subgroup: 2.3.5.7.11

Comma list: 176/175, 540/539

Mapping to lattice: [⟨0 0 -3 1 -5], ⟨0 1 0 1 1]]

Lattice basis:

7/6 length = 0.5167, 3/2 length = 1.3055
Angle (7/6, 3/2) = 79.0940

Optimal tunings:

  • WE: ~2 = 1199.2336 ¢, ~3/2 = 702.4159 ¢, ~12/7 = 929.3128 ¢
