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