By a //chromatic pair// is meant a pair of MOS in some rank two temperament (which may often be a [[Just intonation subgroups|subgroup temperament]]) in which the smaller of the pair is analogous to Meantone[7], the diatonic scale, and the larger to Meantone[12], the chromatic scale. Because on a standard keyboard the smaller scale is given by the white keys, smaller scale of the pair is called "albitonic" from the Latin word for "white". ==Greeley== Subgroup: 2.5/3.7/3.11/3 Commas: 121/120, 126/125 POTE generator: ~11/10 = 156.055 Map: [<1 1 2 2|, <0 -2 -6 -1|] EDOs: 8, 15, 23, 77, 100 Badness: 0.0634 [[greeley8|Eight note albitonic scale]] [[greeley15|Fifteen note chromatic scale]] ==Pepperoni== Subgroup: 2.3.11/7.13/7 Commas: 352/351, 364/363 POTE generator: ~3/2 = 704.052 Map: [<1 0 7 12|, <0 1 -4 -7|] EDOs: 5, 7, 12, 17, 29, 46, 75, 196, 271 Badness: 0.0659 [[pepperoni7|Albitonic scale]] [[pepperoni12|Chromatic scale]] ==Bridgetown== Subgroup: 2.3.11/5.13/5 Commas: 352/351, 676/675 POTE generator: ~15/13 = 248.285 Map: [<1 0 -6 -1|, <0 2 9 3|] EDOs: 5, 9, 14, 19, 24, 29 Badness: 0.0173 ===Albitonic scale=== ! bridgetown9.scl !
