SN scales are [[chirality|mirror-symmetric]], and may be uniquely defined by a ''step signature'' - a generalization of the MOS signature into arbitrary rank. | SN scales are [[chirality|mirror-symmetric]], and may be uniquely defined by a ''step signature'' - a generalization of the MOS signature into arbitrary rank. | ||

The diatonic scale can be generated by iterating a) twice, introducing first the octave, then the perfect fifth, and then iterating b) 3 times. It has step signature 5'''L'''2'''s''', and in the symmetric mode, it has step arrangement '''LsLLLsL'''. No other arrangement of 5 large and 2 small step sizes results in a SN scale. | The diatonic scale can be generated by iterating a) twice, introducing first the octave, then the perfect fifth, and then iterating b) 3 times.
