Aberrismic theory: Difference between revisions

In [[groundfault]]'s '''aberrismic theory''', an '''aberrisma''' is a type of scale step which can be added to a scale pattern to turn it into a scale of one rank higher. Aberrismas are a new category of melodic steps that are smaller than the steps in the original scale, which are prototypically whole tones and semitones; the typical range for an aberrisma is 20 to 60 [[cents]], with optimal size approximately 40 cents according to groundfault. Ternary patterns such as [[Diasem]] (5L2m2s), [[blackdye]] (5L2m3s), and [[diamech]] (5L2m4s) can be made by adding aberrismas to diatonic scales.
