{{Harmonics intro|4}} The notes of this scale create a [[4:5:6:7|harmonic seventh chord]]. | |||
The smallest [[edo]]s that maintain 25% or lower relative error on all intervals of this scale are [[10edo]] and [[15edo]], though they are not very accurate. The next two edos, [[22edo]] and [[31edo]], are the smallest that approximate this scale with appreciable accuracy. | |||
