The hexatonic modal family [1257, 669, 1191, 2643, 3369, 933] is the negative of the hexatonic modal family [363, 1419, 1581, 1713, 2229, 2757]


The inverse of a scale is a reflection using the root as its axis. The inverse of 1257 is 741

Scale 741Scale 741, Ian Ring Music Theory


Only scales that are chiral will have an enantiomorph. Scale 1257 is chiral, and its enantiomorph is scale 741
