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

The supra/quasisuper version is proper, but the superpyth/ultrapyth version is improper (it does not become proper until you add 5 more notes to form the superpyth 22-note scale).
