As a concrete [[interval region]], it is typically near 700 [[cent]]s in size, distinct from semidiminished fifths of rougly 650 cents. A rough tuning range for the perfect fifth is about 670 to 730 [[cents]] according to [[Margo Schulter]]'s theory of interval regions. Another common range is the stricter range from 686 to 720 cents, which generates a diatonic scale.

This article covers intervals from 650 to 750 cents, which is very wide, but is done to avoid having to make articles for the tiny interval regions that would otherwise be required to cover the entire span of intervals.
