Postmodernism in music is not a distinct musical style, but rather refers to music of the postmodern era. Postmodernist music, on the other hand, shares characteristics with postmodernist art—that is, art that comes after and reacts against modernism (see Modernism in Music). Rebecca Day, Lecturer in Music Analysis, writes "within music criticism, postmodernism is seen to represent a conscious move away from the perceptibly damaging hegemony of binaries such as aestheticism/formalism, subject/object, unity/disunity, part/whole, that were seen to dominate former aesthetic discourse, and that when left unchallenged (as postmodernists claim of modernist discourse) are thought to de-humanise music analysis".
