In this paper, pitch-class sets are analyzed in terms of their intervallic structures and those related by transposition are called a set type. Then, non-inversionally-symmetrical set classes are split into two set ...

In post-tonal theory, set classes are normally elements of Z(12) and are characterized by their interval-class vector. Those being non-inversionally-symmetrical can be split into two set types related by inversion, ...
