Modes are the rotational transformation of this scale. Scale 147 can be rotated to make 3 other scales. The 1st mode is itself.

2nd mode:
Scale 2121
Scale 2121, Ian Ring Music Theory
3rd mode:
Scale 777
Scale 777, Ian Ring Music Theory
4th mode:
Scale 609
Scale 609, Ian Ring Music Theory


This is the prime form of this scale.


The tetratonic modal family [147, 2121, 777, 609] 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 147 is 2337

Only scales that are chiral will have an enantiomorph. Scale 147 is chiral, and its enantiomorph is scale 2337
