Original Wikitext content:
The //68 equal temperament//, often abbreviated 68-tET, 68-EDO, or 68-ET, is the scale derived by dividing the octave into 68 equally-sized steps. Each step represents a frequency ratio of 17.65 cents; this is half of the step size of [[34edo]], which does well in the 5-limit but not so well in the 7-limit, and one quarter the size of [[17edo]], which does well in the [[3-limit]], but not so well in the [[5-limit]]. The luck continues; 68 is a strong [[7-limit]] system, but does not do as well for in [[11-limit]]; though it's certainly usable for that purpose, it does not represent the 11-limit diamond [[consistent]]ly. As a 7-limit system it tempers out 2048/2025, 245/243, 4000/3969, 15625/15552, 3136/3125, 6144/6125 and 2401/2400. It supports octacot, shrutar, hemiwuerschmidt, hemikleismic, clyde and neptune temperaments, and supplies the optimal patent val for 11-limit hemikleismic. It is a sharp-tending system, with the third, fifth and seventh harmonics all sharp. Diatonic scales: Negative comma: [[tel:14 14 -1 14 14 14 -1|14 14 -1 14 14 14 -1]] (E is sharper than F, and B is sharper than C5) Superpyth: [[tel:12 12 4 12 12 12 4|12 12 4 12 12 12 4]] Flattone: [[tel:10 10 9 10 10 10 9|10 10 9 10 10 10 9]] Inverse: 8 [[tel:8 14 8 8 8 14|8 14 8 8 8 14]]
