New Complexity
Though often atonal, highly abstract, and dissonant in sound, the "New Complexity" is most readily characterized by the use of techniques which require complex musical notation. This includes extended techniques, microtonality, odd tunings, highly disjunct melodic contour, innovative timbres, complex polyrhythms, unconventional instrumentations, abrupt changes in loudness and intensity, and so on. The diverse group of composers writing in this style includes Richard Barrett, Brian Ferneyhough, Claus-Steffen Mahnkopf, James Dillon, Michael Finnissy, James Erber, and Roger Redgate.
