A perfect fourth is an interval that is near 500 [[Cent|cents]] in size, distinct from augmented fourths (a type of [[tritone]], about 600 cents). A rough tuning range for the perfect fourth is about 450 to 550 [[cents]], though this is extremely wide; some might prefer to restrict it to around 470-530 cents.
