Original Wikitext content:
=__**Welcome to the Temperament Orphanage**__= ==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. 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. ==Gravity - 5-limit - tempers 129140163/128000000== 5&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 -> Dicot -> Porcupine -> Tetracot -> Amity continuum, whereby (81/80)^n = 25/24. POTE generator: ~27/20 = 516.844 cents Map: [<1 5 12|, <0 -6 -17|] EDOs: 7, 58, 65, 137, 202, 267, 469 Tempering out 65625/65536 does little damage to tuning accuracy but results in a very complex temperament. [[@http://x31eq.com/cgi-bin/rt.cgi?ets=65_7&limit=5|http://x31eq.com/cgi-bin/rt. cgi?ets=65_7&limit=5]] ==Absurdity - 5-limit - tempers 10460353203/10240000000== 5&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. [[@http://x31eq.com/cgi-bin/rt.cgi?ets=7_84&limit=5|http://x31eq.com/cgi-bin/rt. cgi?ets=7_84&limit=5]] ==**7&49** - 5-limit - tempers 5000000/4782969== 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. POTE generator: ~3/2 = 706.288 cents Map: [<7 0 -6|, <0 1 2|] EDOs: 7, 42, 49, 56, 119 Adding 875/864 to the commas extends this to the 7-limit: POTE generator: ~3/2 = 705.613 cents Map: [<7 0 -6 53|, <0 1 2 -3|] EDOs: 7, 56, 63, 119 [[http://x31eq.com/cgi-bin/rt.cgi?ets=7_49&limit=5]] ==**7&**49c - 5-limit - tempers 78125/69984== 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. Comma: 78125/69984 POTE generator: ~3/2 = 706.410 cents Map: [<7 0 5|, <0 1 1|] EDOs: 7, 56 [[http://x31eq.com/cgi-bin/rt.cgi?ets=7_49c&limit=5]]
