A 30 tone well tempered nonet (30WTN) is related to well temperaments of 25edo and 26edo, but with a nonet rather than the 2/1 being constant. It alternates division of the just perfect fifth into 15 equal parts (15EDF) with sequences of ten equal steps of 40 to 53.333 cents each. This will create fifteen equally-spaced intervals between an interval between 600 and 800 cents and the just perfect fifth.
