[[toc|flat]] =Wuerschmit= The 5-limit parent comma for the wuerschmidt family is 393216/390625, known as Wuerschmidt's comma. Its monzo is |17 1 -8>, and flipping that yields <<8 1 -17|| for the wedgie. This tells us the generator is a major third, and that to get to the interval class of fifths will require eight of these. In fact, (5/4)^8 * 393216/390625 = 6. 14/53 or 21/65 are excellent generators, though 9/34 also makes sense and using 19edo is possible. Other tunings include 72edo, 87edo, 140edo and 164edo. Another tuning solution is to sharpen the major third by 1/8th of a Wuerschmift comma, which is to say by 1.43 cents, and thereby achieve pure fifths; this is the minimax tuning. Wuerschmidt is well-supplied with MOS scales, with 10, 13, 16, 19, 22, 25, 28 31 and 34 note MOS all possibilities. [[POTE tuning|POTE generator]]: 387.799 Map: [<1 7 3|, <0 -8 -1|] EDOs: 31, 34, 65, 164 ==Seven limit children== The second comma of the [[Normal lists|normal comma list]] defines which 7-limit family member we are looking at. Wurschmidt adds |12 3 -6 -1>, worschmidt adds 65625/65536 = |-16 1 5 1>, whirrschmidt adds 4375/4374 = |-1 -7 4 1> and hemiwuerschmidt adds 6144/6125 = |11 1 -3 -2>. =Wurschmidt= Wurschmidt, aside from the commas listed above, also tempers out 225/224. [[31edo]] or [[127edo]] can be used as tunings. Wurschmidt has <<8 1 18 -17 6 39|| for a wedgie. It extends naturally to an 11-limit version <<8 1 18 20 ,,,|| which also tempers out 99/98, 176/175 and 243/242. [[127edo]] is again an excellent tuning for 11-limit wurschmidt, as well as for minerva, the 11-limit rank three temperament tempering out 99/98 and 176/175. Commas: 225/224, 8748/8575 [[POTE tuning|POTE generator]]: 387.383 Map: [<1 7 3 15|, <0 -8 -1 -18|] EDOs: 31, 127 =Worschmidt= Worschmidt tempers out 126/125 rather than 225/224, and can use [[31edo]], [[34edo]], or [[127edo]] as a tuning. If 127 is used, note that the val is <127 201 295 356| and not <127 201 295 357| as with wurschmidt. The wedgie now is <<8 1 -13 -17 -43 -33|. In practice, of course, both mappings could be used ambiguously, which might be an interesting avenue for someone to explore. Commas: 126/125, 33075/32768 [[POTE tuning|POTE generator]]: 387.392 Map: [<1 7 3 -6|, <0 -8 -1 13|] EDOs: 31, 127 =Whirrschmidt= [[99edo]] is such a good tuning for whirrschimdt that we hardly need look any farther. Unfortunately, the temperament while accurate is complex, with <<8 1 52 -17 60 118|| for a wedgie. Commas: 4375/4374, 393216/390625 [[POTE tuning|POTE generator]]: 387.881 Map: [<1 7 3 38|, <0 -8 -1 -52|] EDOs: 31, 34, 99 =Hemiwuerschmift= Hemiwuerschmidt, which splits the major third in two and uses that for a generator, is the most important of these temperaments even with the rather large complexity for the fifth. It tempers out 3136/3125, 6144/6125 and 2401/2400. [[68edo]], [[99edo]] and [[130edo]] can all be used as tunings, but 130 is not only the most accurate, it shows how hemiwuerschmidt extends to a higher limit temperament, <<16 2 5 40 -39 -49 -48 28... Commas: 2401/2400, 3136/3125 [[POTE tuning|POTE generator]]: 193.898 Map: [<1 15 4 7|, <0 -16 -2 -5|] EDOs: 31, 99, 229
