In terms of [[interval region]]s, "comma" refers to an interval flatter than about 30{{cent}}, and "diesis" refers to an interval between about 30 and 60{{cent}}. In Sagittal notation, a comma is specifically defined as between half of the Pythagorean comma [-19 12⟩ and half of the pythagorean 17-fifths diesis [27 -17⟩, about 11.7{{c}} to 33.4{{c}}, and a diesis is defined as between the comma upper bound and half of the pythagorean 19-fifths apotome-plus-comma [-30 19⟩, about 68.6{{c}}. | ||
