As a concrete [[interval region]], it is typically near 1000{{c}} in size, distinct from the [[major seventh]] of roughly 1100{{c}} and the [[neutral seventh]] of roughly 1050{{c}}. A rough tuning range for the minor seventh is about 960 to 1025{{c}} according to [[Margo Schulter]]'s theory of interval regions. | As a concrete [[interval region]], it is typically near 1000{{c}} in size, distinct from the [[major seventh]] of roughly 1100{{c}} and the [[neutral seventh]] of roughly 1050{{c}}.

This article covers intervals between 940 and 1040 cents. The outer range of this might be too extreme to call "minor sevenths", but this is done so that one can find what they're looking for easily. | |||
