Circle diagram.

A 7-limit bihexany. This creates a scale of 1 9/8 7/6 135/112 5/4 27/20 7/5 81/56 3/2 27/16 7/4 27/14 2/1, with steps of 9/8 28/27 405/392 28/27 27/25 28/27 405/392 28/27 9/8 28/27 54/49 28/27. This is the fourth and final method expanding out the base hexany that puts a 9/8 above the root and gives you a total of 5 perfect fifths to construct chords with, and the most melodically effective one, dividing the smallest steps near precisely in two while cancelling out many of the composite ratios, giving you a strong selection of familiar and xenharmonic chords.
