'''12L 7s''' is the MOS pattern of the [[meantone]] mega-chromatic scale. This MOS separates its small steps by intervals of 2L-2L-2L-1L-2L-2L-1L like the familiar [[12edo]] diatonic scale. The perfect fifth which generates it measures 11\19 (694.737 cents) to 7\12 (700 cents). | '''12L 7s''' is the MOS pattern of the [[meantone]] enharmonic or mega-chromatic scale.
