Z-Relation
Glossary
Set Theory
Two set classes are Z-related when they share the same interval content but are not related by involution. Allen Forte assigned Forte numbers which included a Z to indicate which set classes had Z-relations. (According to Forte, the letter Z stands for “zygotic.”)
In 12-TET set classes with cardinality six are also always complements of their Z-relations.
