Modes are the rotational transformation of this scale. Scale 149 can be rotated to make 3 other scales. The 1st mode is itself.

2nd mode:
Scale 1061
Scale 1061, Ian Ring Music Theory
3rd mode:
Scale 1289
Scale 1289, Ian Ring Music Theory
4th mode:
Scale 673
Scale 673, Ian Ring Music Theory


This is the prime form of this scale.


The tetratonic modal family [149, 1061, 1289, 673] is the negative of the octatonic modal family [1391, 1469, 1781, 1963, 2743, 3029, 3419, 3757]


The inverse of a scale is a reflection using the root as its axis. The inverse of 149 is 1313

Scale 1313Scale 1313, Ian Ring Music Theory


Only scales that are chiral will have an enantiomorph. Scale 149 is chiral, and its enantiomorph is scale 1313
