Aberrismic theory

In groundfault's aberrismic theory, an aberrisma is a type of scale step which can added to a MOS scale to turn it into a ternary scale. Aberrismas are a new category of melodic steps that are smaller than the existing steps in the MOS; the typical range for an aberrisma is 20 to 60 cents; groundfault holds the optimal size of an aberrisma to be approximately 40 cents. Ternary patterns such as Diasem (5L2m2s), Blackdye (5L2m3s), and Diamech (5L2m4s) can by made by adding aberrismas to diatonic scales.
