The semicomma 2109375/2097152 = |-21 3 7> is tempered out by the members of the semicomma family. It doesn't have much independent existence as a 5-limit temperament, since its generator has a natural interpretation as 7/6, leading to orwell temperament. | The semicomma 2109375/2097152 = |-21 3 7> is tempered out by the members of the semicomma family.

Miracle temperament divides the fifth into 6 equal steps. A 21-note scale called "blackjack" and a 31-note scale called "canasta" have some useful properties. It's the most efficient 11-limit temperament for many purposes with a tuning close to 72-EDO. | Miracle temperament divides the fifth into 6 equal steps.

Not a family or clan, but related by the fact that 126/125, the septimal semicomma or starling comma is tempered out, are myna, sensi, valentine, casablanca and nusecond temperaments, not to mention meantone, keemun, muggles and opossum. | |||

If a 5-limit comma defines a family of rank two temperaments, then we might say a comma belonging to another <a class="wiki_link" href="/Just%20intonation%20subgroups">subgroup</a> of the 7-limit can define a clan. In particular we might say a triprime comma (one with exactly three primes in the factorization) can define a clan. Notable among such clans are the temperaments which temper out the gamelisma, 1029/1024. We can modify the definition of <a class="wiki_link" href="/Normal%20lists">normal comma list</a> for clans by changing the ordering of prime numbers, and using this to sort out clan relationships.<br /> | If a 5-limit comma defines a family of rank two temperaments, then we might say a comma belonging to another <a class="wiki_link" href="/Just%20intonation%20subgroups">subgroup</a> of the 7-limit can define a clan.
