'''5L 12s''' is the MOS pattern of the [[superpyth]] mega-chromatic scale. In contrast to the [[12L 5s|schismic mega-chromatic scale]], in which mega-chromatic semitones (negative diminished seconds) are smaller than chromatic semitones, here the reverse is true: mega-chromatic semitones are larger than chromatic semitones, so the [[5L 7s|diatonic scale]] subset is actually [[Rothenberg propriety|improper]]. | '''5L 12s''' is the MOS pattern of the [[superpyth]] mega-chromatic scale.
