- 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-2 metric microtemperaments, which temper out the meter (monzo: [-11 2 7 -3⟩, ratio: 703125/702464).
Temperaments discussed elsewhere include:
- Meantone (+81/80) → Meantone family
- Term (+32805/32768) → Schismatic family
- Undim (+5120/5103) → Undim family
- Quintupole (+4000/3969) → Quintaleap family
- Trinity (+1600000/1594323) → Amity family
- Marfifths (+10976/10935) → Kleismic family
- Enneadecal (+4375/4374) → Ragismic microtemperaments
- Triwell (+1029/1024) → Semicomma family
- Tertiaseptal (+2401/2400) → Breedsmic temperaments
- Grendel (+6144/6125) → Porwell temperaments
- Qak (+420175/419904) → Wizmic microtemperaments

Geb
- For the 5-limit version, see Syntonic–chromatic equivalence continuum #Geb (5-limit).
The geb temperament (171 & 506, named after the earth god of ancient Egyptian religion) tempers out the meter and the euzenius comma (78125000/78121827) as well as scheme comma (14348907/14336000) in the 7-limit. Osiris (171 & 670, named after the eldest son of Geb) tempers out the same 5-limit comma as the geb, but with the breedsma rather than the meter tempered out.
