As a concrete [[interval region]], it is typically near 500 cents in size, distinct from the [[semiaugmented fourth]] of roughly 550 cents. A rough tuning range for the perfect fourth is about 470 to 530 cents according to [[Margo Schulter]]'s theory of interval regions. Another common range is the stricter range from 480 to 514 cents, which generates a diatonic scale. | As a concrete [[interval region]], it is typically near 500 cents in size, distinct from the [[semiaugmented fourth]] of roughly 550 cents.
