Scale 731 |

The heptatonic modal family [1747, 2921, 877, 1243, 2669, 1691, 2893] is the negative of the pentatonic modal family [587, 601, 713, 1609, 2341]

The inverse of a scale is a reflection using the root as its axis. The inverse of 1747 is 2413

Scale 2413 | Locrian nr.2 |

Only scales that are chiral will have an enantiomorph. Scale 1747 is chiral, and its enantiomorph is scale 2413

Scale 2413 | Locrian nr.2 |

These are other scales that are similar to this one, created by adding a tone, removing a tone, or moving one note up or down a semitone.
