| [[3edo]] is much less used as a scale, rather as a chord. In many [[5L 2s|diatonic-based]] [[interval region]] schemes, one step of 3edo is known as a major third, and the stacking of them is the augmented triad.
| |
| | |
| Usage of the [[5/4]] major third as one step of 3edo by tempering out [[128/125]], and therefore using 3edo as a augmented triad produced by stacking two major thirds is one of the features of standard Western music theory, and is supported by [[12edo]]. See [[Augmented family]] for a collection of such temperaments.
| |
| | |
| [[24/19]] is much closer to 1/3-octave than 5/4, and while it is not a microtemperament, a lot of equal divisions support it.
| |
| | |
| An interval closer to 1\3 is [[63/50]], with the associated comma being the landscape comma. See [[Landscape family]] for a collection of rank-3 temperaments tempering it out.
| |
| | |
| There are nonetheless other less common temperaments which divide the octave in three.
