Modes

Modes are the rotational transformation of this scale. Scale 165 can be rotated to make 3 other scales. The 1st mode is itself.

2nd mode:
Scale 1065
Scale 1065, Ian Ring Music Theory
3rd mode:
Scale 645

Prime

This is the prime form of this scale.

Negative

The tetratonic modal family [165, 1065, 645, 1185] is the negative of the octatonic modal family [1455, 1515, 1725, 1965, 2775, 2805, 3435, 3765]

Inverse

The inverse of a scale is a reflection using the root as its axis. The inverse of 165 is 1185
