== 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.

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.

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.
