The two extremes, equalized and paucitonic, are degenerate cases. An equalized MOS has L equal to s, so the MOS pattern is no longer apparent. A paucitonic MOS has s = 0, merging adjacent tones s apart into a single tone. In both cases, the MOS structure is no longer valid. | The two extremes, equalized and paucitonic, are degenerate cases.

In between the nine specific ratios there are eight ranges of ratios. Each range has a name. These names are useful for classifying MOS tunings which don't match any of the nine simple step ratios. | In between the nine specific ratios there are eight ranges of ratios. (Hypohard is a combination of the minihard and quasihard ranges.) Each range has a name. These names are useful for classifying MOS tunings which don't match any of the nine simple step ratios. | ||
