	The minor sixth, as a concrete interval region, is typically near 800{{c}} in size, distinct from the [[major sixth]] of roughly 900{{c}} and the [[neutral sixth]] of roughly 850{{c}}. A rough tuning range for the minor sixth is about 760 to 828{{c}} according to [[Margo Schulter]]'s theory of interval regions. ''Minor sixth'' in this sense refers both to the ~740–840{{c}} range as a whole, and to a specific subdivision within it (~785–840{{c}}) as opposed to subminor sixths; minor sixths flat of this are often called "subminor sixths".

			As a diatonic interval category, a minor sixth is an interval that spans five scale steps in the [[5L 2s\|diatonic]] scale with the minor (narrower) quality. It is generated by stacking 4 fourths [[Octave reduction\|octave reduced]], and depending on the specific tuning, it ranges from 720 to 857{{cent}} ([[5edo\|3\5]] to [[7edo\|5\7]]).

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