The hexatonic modal family [1489, 349, 1111, 2603, 3349, 1861] is the negative of the hexatonic modal family [349, 1111, 1489, 1861, 2603, 3349]


The inverse of a scale is a reflection using the root as its axis. The inverse of 1489 is 373

Scale 373Scale 373, Ian Ring Music Theory


Only scales that are chiral will have an enantiomorph. Scale 1489 is chiral, and its enantiomorph is scale 373
