==These temperaments need to be adopted into a family==


These are some temperaments that were found floating around. It isn't clear what family they belong to, so for now they're in the temperament orphanage. Should you know how to match these temperaments back up with their temperament family, feel free to remove them from the orphanage and put them on the right page. If a temperament listed doesn't have a name, give it a name.
'''Welcome to the temperament orphanage!'''


Please give a short description of whatever temperament you leave here so that someone can help to match this temperament back to its rightful progenitors.
These temperaments need to be adopted into a family.

These are some temperaments that were found floating around. It is not clear what family they belong to, so for now they are in the temperament orphanage.

5&amp;67 temperament. It equates (81/80)^4 with 25/24. It is so named because the generator is a "Grave" fifth (or 27/20). It is part of the Mavila -&gt; Dicot -&gt; Porcupine -&gt; Tetracot -&gt; Amity continuum, whereby (81/80)^n = 25/24.

Tempering out 65625/65536 does little damage to tuning accuracy but results in a very complex temperament.

== Lafa (65 & 441) ==
This temperament was named by [[Petr Pařízek]] in 2011, referring to the characteristic that stacking 12 generators makes 6/1 – "l" for 12, "f" for 6<ref>[https://yahootuninggroupsultimatebackup.github.io/tuning/topicId_101780.html Yahoo!

Subgroup: 2.3.5
5&amp;84 temperament. So named because this is just an absurd temperament. If you have a better name for it then it doesn't have to be absurdity anymore. The generator is 81/80 and the period is 800/729, which is (10/9) / (81/80). This is also a part of the syntonic-chromatic equivalence continuum, in this case where (81/80)^5 = 25/24.

==**7&amp;49** - 5-limit - tempers 5000000/4782969==
Comma list: {{monzo| 77 -31 -12 }}
This is a fairly obvious temperament; it just equates 7 10/9's with a 2/1, hence the period is 10/9. One generator from 5\7 puts you at 3/2, two generators from 2\7 puts you at 5/4.

Adding 875/864 to the commas extends this to the 7-limit:

==**7&amp;**49c - 5-limit - not sure what is tempered==
[[Category:Regular temperament theory]]
This is similar to the above, but provides a less complex avenue to 5, but this time at the sake of accuracy. One generator from 5\7 puts you at 3/2, and one generator from 2\7 puts you at 5/4.
