Swetismic temperaments

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.

This is a collection of rank-3 temperaments tempering out the swetisma (ratio: 540/539, monzo: [2 3 1 -2 -1⟩). For the rank-4 swetismic temperament, see Catalog of rank-4 temperaments #Swetismic (540/539).

Temperaments discussed elsewhere are:

• Terpsichore (+81/80) → Didymus rank-3 family
• Big brother (+99/98 or 121/120) → Biyatismic clan
• Octarod (+100/99 or 245/243) → Sensamagic family
• Aplonis (+126/125) → Starling family
• Guanyin (+176/175) → Orwellismic family
• Marvel (+225/224 or 385/384) → Marvel family
• Jove (+243/242 or 441/440) → Breed family
• Uni (+896/891) → Hemimage family
• Gamel (+1029/1024) → Gamelismic family
• Claudius (+2048/2025) → Diaschismic rank-3 family
• Octasand (+2200/2187) → Octagar family
• Gariboh (+3125/3087) → Gariboh family
• Siebog (+3136/3125) → Hemimean family
• Laka (+5120/5103) → Hemifamity family
• Jupiter (+5632/5625) → Porwell family
• Albus (+8019/8000) → Cataharry family

Considered below are indra, hades, minos, persephone and hypnos, in the order of increasing badness.
