Modes are the rotational transformation of this scale. Scale 1809 can be rotated to make 4 other scales. The 1st mode is itself.

2nd mode:
Scale 369
Scale 369: Laditonic, Ian Ring Music TheoryLaditonic
3rd mode:
Scale 279
Scale 279: Poditonic, Ian Ring Music TheoryPoditonicThis is the prime mode
4th mode:

The pentatonic modal family [1809, 369, 279, 2187, 3141] (Forte: 5-13) is the complement of the heptatonic modal family [375, 1815, 1905, 2235, 2955, 3165, 3525] (Forte: 7-13)


The inverse of a scale is a reflection using the root as its axis. The inverse of 1809 is 285
