Original Wikitext content:
This is the MOS pattern of the [[Meantone family|meantone]] chromatic scale, which is the only notable harmonic entropy minimum in this range of possible scales. In meantone, "diatonic" semitones (~16/15), such as appear in the [[5L 2s|diatonic scale]], for example B-C, are larger than "chromatic" semitones (~25/24), the intervals by which flats and sharps alter pitches. The meantone chromatic scale is [[Rothenberg propriety|proper]]. ||||||||||||~ Generator ||~ in cents ||~ Comments || ||= 3\7 ||= ||= ||= ||= ||= ||< 514.286 ||= || ||= ||= ||= ||= ||= ||= 20\47 ||< 510.638 ||= || ||= ||= ||= ||= ||= 17\40 ||= ||< 510.000 ||= || ||= ||= ||= ||= ||= ||= 31\73 ||< 509.589 ||= || ||= ||= ||= ||= 14\33 ||= ||= ||< 509.091 ||= || ||= ||= ||= ||= ||= ||= 39\92 ||< 508.696 ||= || ||= ||= ||= ||= ||= 25\59 ||= ||< 508.475 ||= || ||= ||= ||= ||= ||= ||= 36\85 ||< 508.235 ||= || || || || || || || || 507.741 || || ||= ||= ||= 11\26 ||= ||= ||= ||< 507.692 ||= || || || || || || || || 507.643 || || ||= ||= ||= ||= ||= ||= 41\97 ||< 507.216 ||= || ||= ||= ||= ||= ||= 30\71 ||= ||< 507.042 ||= Flattone || ||= ||= ||= ||= ||= ||= 49\116 ||< 506.897 ||= Flattone || ||= ||= ||= ||= 19\45 ||= ||= ||< 506.667 ||= Flattone || ||= ||= ||= ||= ||= ||= 46\109 ||< 506.422 ||= Flattone || ||= ||= ||= ||= ||= 27\64 ||= ||< 506.250 ||= Flattone || ||= ||= ||= ||= ||= ||= 35\83 ||< 506.024 ||= || ||= ||= 8\19 ||= ||= ||= ||= ||< 505.263 ||= Boundary of propriety: generators smaller than this are proper.
