Augmented family

Jump to navigation Jump to search

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 12 EDO, 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 comma list defines which 7-limit family member we are looking at. August adds 36/35, augene 64/63, hexe 256/245, hemiaug 245/243, and triforce 49/48. Hexe splits the period to 1/6 octave, and hemiaug the generator, giving quartertones instead of semitones.

Niner

Niner gives 9 as the complexity of an otonal tetrad, tying it with augene as a temperament supported by 27EDO. Niner[18], therefore, has nine such tetrads.
