Modes are the rotational transformation of this scale. Scale 409 can be rotated to make 4 other scales. The 1st mode is itself.

2nd mode:
Scale 563

The pentatonic modal family [409, 563, 2329, 803, 2449] is the negative of the heptatonic modal family [823, 883, 1843, 2459, 2489, 2969, 3277]


The inverse of a scale is a reflection using the root as its axis. The inverse of 409 is 817
