72ed5 is related to [[31edo]], but with the 5/1 rather than the [[2/1]] being just. The octave is slightly compressed (about 0.3372 cents). This tuning has a meantone fifth as the number of divisions of the 5th harmonic is multiple of 4.
72ed5 is related to [[31edo]], but with the 5/1 rather than the [[2/1]] being just. The octave is slightly compressed (about 0.3372 cents). Like 31edo, 72ed5 is [[consistent]] through the [[integer limit|12-integer-limit]], but it has a flat tendency, with [[prime harmonic]]s 2, [[3/1|3]], [[7/1|7]], and [[11/1|11]] all tuned flat. It [[support]]s [[meantone]] as the number of divisions of the 5th harmonic is multiple of 4.

=== Subsets and supersets ===
72 is a [[largely composite]] number. Since it factors into primes as {{nowrap| 2<sup>3</sup> × 3<sup>2</sup> }}, 72ed5 has subset ed5's {{EDs|equave=5| 2, 3, 4, 6, 8, 9, 12, 18, 24, and 36 }}.
