A rough

tuning range for the minor third is about 260 to 330{{c}} according to [[Margo Schulter]]'s theory of interval regions. ''Minor third'' in this sense refers both to the ~240–340{{c}} range as a whole, and to a specific subdivision within it (~285–340{{c}}) as opposed to subminor thirds; minor thirds flat of this are often called "subminor thirds".

In [[just intonation]], an interval may be classified as a minor third if it is reasonably mapped to  two steps of the diatonic scale and four steps of the chromatic scale.

 

In the [[5L 2s|diatonic]] scale, a minor third spans two scale steps with the minor (narrower) quality. It is generated by stacking 3 fourths [[octave reduction|octave reduced]], and depending on the specific tuning, it ranges from 240 to 343{{cent}} ([[5edo|1\5]] to [[5edo|2\7]]).

The following table lists the best tuning of 7/6 and 6/5, as well as other minor thirds if present, in various significant [[edo|EDO]]s.

Intervals between 267 and 343{{c}} generate the following [[mos|MOS]] scales:
