Valentine scales
Semi-equalized Armodue
One step of 16edo (75 cents) is nearly equal to two steps (2\31) of 31edo (77.42 cents). If we take the latter as a base, we get semi-equalized Armodue. In this temperament there is inevitably a smaller microtone (eka between the notes '7#' and '8'). leading to the 16 note MOS Valentine[16] of valentine temperament. Similarly we might use three steps of 46edo, 3\46, 78.26 cents, or five steps of 77edo, 77.92 cents.
Semi-equalized Armodue provides a balance between the symmetry of the equalized system and the purity of natural intervals: intervals of semi-equalized Armodue are very pure, and at the same time it preserves the symmetry of the equalized system and its interval sizes almost unchanged.
