Luna family
- 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 luna family tempers out the luna comma, 274877906944/274658203125, which has a monzo of [38 -2 -15⟩. It divides 16/3 into fifteen parts, two of which make 5/4. It also divides 9/8 in five and 3/2 in three.
Temperaments discussed elsewhere include:
- Subneutral (+2401/2400) → Breedsmic temperaments
- Hemithirds (+3136/3125) → Hemimean clan
Luna
Hemithirds, a strong extension of didacus that tempers out 1029/1024 alongside 3136/3125, might be considered the main 7-limit extension to luna of practical interest, as 7/4 is found at only 5 generators. However, luna is an undoubted microtemperament of the 5-limit in its own right, supported by systems like 118edo and 441edo, and therefore merits consideration of other extensions to the 7-limit, which are documented on this page. Though of very high complexity, they continue the level of accuracy of 5-limit luna.
