définition : “The selection of particular subsets to describe a set usually must involve (...) considerations, [among which] the notion of invariance plays an important role.”^[1] When sets are transposed or inverted and transposed their pitch class content may remain completely the same, i.e. become redundant, partly change, or completely change.^[2]

grammaire : noun

contexte : to what extent is the invariance (...) reciprocal

source : FORTE 1973: 106

contexte : the greater the symmetry, i.e. intervallic symmetry, the greater the amount of invariance among sets.

entrée : pc invariance

grammaire : compound noun

note : “pc invariance” stands for “pitch-class invariance”

contexte : partial pc invariance among sets can be a marker that certain pcs (the invariant ones) are being stressed or made salient or that these pcs are acting as links among different sets.
