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. | 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. | ||
