Modes are the rotational transformation of this scale. Scale 291 can be rotated to make 3 other scales. The 1st mode is itself.

2nd mode:
Scale 2193
Scale 2193, Ian Ring Music Theory
3rd mode:
Scale 393
Scale 393, Ian Ring Music Theory
4th mode:
Scale 561
Scale 561, Ian Ring Music Theory


This is the prime form of this scale.


The tetratonic modal family [291, 2193, 393, 561] is the negative of the octatonic modal family [951, 1767, 1851, 2523, 2931, 2973, 3309, 3513]


The inverse of a scale is a reflection using the root as its axis. The inverse of 291 is 2193
