	{{~~Fractional~~-octave ~~navigation~~\|4}}[[4edo]] is much less used as a scale, rather as a chord. In many [[5L 2s\|diatonic-based]] [[interval region]] schemes, one step of 4edo is known as a minor third, and the stacking of them is the diminished seventh chord.		{{Infobox fractional-octave\|4}}[[4edo]] is much less used as a scale, rather as a chord.

	Usage of the [[6/5]] minor third as one step of 4edo by tempering out [[648/625]], and therefore using 4edo as a diminished seventh chord produced by stacking three minor thirds is one of the features of standard Western music theory, and is supported by [[12edo]]. See [[Dimipent family]] for a collection of such temperaments.
