The 5-limit parent comma for the augmented family is 128/125, the diesis. Its [[monzo]] is |7 0 -3>, and flipping that yields <<3 0 -7|| for the [[wedgie]]. Hence the period is 1/3 octave, and this is what is used for a major third. The [[generator]] can be taken as a fifth or a semitone, and [[12edo]], with its excellent fifth, is an obvious tuning for 5-limit augmented, though a sharper fifth might be preferred to go with the sharp third. ==Seven limit children== The second comma of the [[Normal lists|normal comma list]] defines which 7-limit family member we are looking at. August adds 36/35, augene 64/63, hexe 256/245, and hemiaug 245/243. Hexe splits the period to 1/6 octave, and hemiaug the generator, giving quarter-tones instead of semitones. ==August== Commas: 36/35, 128/125 [[POTE tuning|POTE generator]]: 696.011 Map: [<3 0 7 -1|, <0 1 0 2|] Wedgie: <<3 0 6 -7 1 14|| EDOs: [[9edo|9]], [[12edo|12]], [[69edo|69]], [[81edo|81]] Badness: 0.0265 ===11-limit=== Commas: 36/35, 45/44, 56/55 POTE generator: ~3/2 = 692.514 Map: [<3 0 7 -1 1|, <0 1 0 2 2|] EDOs: 9, 12, 21, 33, 45, 78 Badness: 0.0202 ===13-limit=== Commas: 27/26, 36/35, 45/44, 56/55 POTE generator: ~3/2 = 688.783 Map: [<3 0 7 -1 1 -3|, <0 1 0 2 2 3|] EDOs: 9, 12, 21, 54 Badness: 0.0184 ==Augene== Commas: 64/63, 126/125 [[POTE tuning|POTE generator]]: 709.257 Map: [<3 0 7 18|, <0 1 0 -2|] Wedgie: <<3 0 -6 -7 -18 -14|| EDOs: [[12edo|12]], [[27edo|27]], [[66edo|66]] Badness: 0.0248 ==Hexe== Commas: 50/49, 128/125 [[POTE tuning|POTE generator]]: 710.963 Map: [<6 0 14 17|, <0 1 0 0|] Wedgie: <<6 0 0 -14 -17 0|| EDOs: [[6edo|6]], [[12edo|12]], [[54edo|54]] Badness: 0.0577 ==Hemiaug== Commas: 128/125, 245/243 [[POTE tuning|POTE generator]]: 445.118 Map: [<3 1 7 -1|, <0 2 0 5|] Wedgie: <<6 0 15 -14 7 35|| EDOs: [[24edo|24]], [[27edo|27]] Badness: 0.0705
