The scales '''''a'''…'''ba'''…'''c''''' and '''''abacaba''''' are [[step-nested scale|step-nested]] (SN) scales, which are mirror-symmetric, and can be uniquely defined by a signature.
The scales '''''a'''…'''ba'''…'''c''''' and '''''abacaba''''' are [[step-nested scale|step-nested]] (SN) scales, which are mirror-symmetric (achiral), and can be uniquely defined by a signature.


SN scales are generated iteratively by placing an instance of a new or the existing smallest step at the top or bottom of every larger step.
