[[49edo]] provides an exceptionally accurate approximation. Because 34 steps ≈ 832.65¢ (acoustic phi) *and* because 34 is a fibonacci number, it naturally follows that 21 steps, its previous fibonacci number, ≈ 514.29¢  (<math>\varphi^{1/\varphi}</math>). This pattern continues, creating a highly accurate golden scale of self-similar frequency relationships at step sizes 2, 3, 5, 8, 13, 21, 34.

[[7edo]] approximates this interval extremely well (0.59c off), as does all edos that are multiples of 7.{{Interval Edo Approximation|interval=134636/100000|interval_name=<math>\varphi^{1/\varphi}</math>}}
