Modes

Modes are the rotational transformation of this scale. Scale 91 can be rotated to make 4 other scales. The 1st mode is itself.

2nd mode:

Prime

This is the prime form of this scale.

Negative

The pentatonic modal family [91, 2093, 1547, 2821, 1729] is the negative of the heptatonic modal family [607, 761, 1993, 2351, 3223, 3659, 3877]

Inverse

The inverse of a scale is a reflection using the root as its axis. The inverse of 91 is 2881

Enantiomorph

Only scales that are chiral will have an enantiomorph. Scale 91 is chiral, and its enantiomorph is scale 2881
