Modes are the rotational transformation of this scale. Scale 201 can be rotated to make 3 other scales. The 1st mode is itself.

2nd mode:
Scale 537

3rd mode:
Scale 579
Scale 579, Ian Ring Music Theory
4th mode:
Scale 2337
Scale 2337, Ian Ring Music Theory


The prime form of this scale is Scale 147

The tetratonic modal family [201, 537, 579, 2337] is the negative of the octatonic modal family [879, 1779, 1947, 2487, 2937, 3021, 3291, 3693]


The inverse of a scale is a reflection using the root as its axis. The inverse of 201 is 609

Only scales that are chiral will have an enantiomorph. Scale 201 is chiral, and its enantiomorph is scale 609
