This genre refers to the recent evolutions in classical music that are more avant-garde or modernistic in nature. It includes Modernism, Serialism, Post Modernism, Experimentalism, Electronic music, Neo-Romanticism, New Simplicity, New Complexity, and Spectral Music.
Modernism is a continuing force in classical music today. To explore this form of music which incorporates such musical devises as atonality one should review the works of Elliott Carter, Lukas Foss, Alexander Goehr, Judith Weir, Thomas Ades, Magnus Lindberg, and Gunther Schuller.
Composers such as Pierre Boulez, Milton Babbit, and Charles Wuorinen lead the genre known as serialism. Compositions are based on an ordered set, or several such sets. This is also known as twelve-tone technique. This genre is considered one of the most important post-war movements.
Post -modernism is a broad term covering several sub genres of musical development. Among these is polystylism, which is music incorporating several different styles, whose composers include William Bolcom and John Zorn. Conceptualism also is in this category; an example of this form would be Alvin Singleton’s “56 Blows”. Minimalism still has a quite prominent role in new composition and can be seen in John Adam’s “On the Transmigration of Souls”, a choral work that commemorated the victims of 9-11.
Experimental music is an important movement in contemporary music that explores the range of expression available to instrumentalists. The work of George Crumb and The Kronos Quartet is an excellent example of this school of thought, and they focus on music which stretches the manner that sound can be drawn out of instruments.
There are a number of festivals dedicated to celebrating cotemporary music including the Gaudeamus Foundation Music Week in Amsterdam, Warsaw Autumn in Poland, the Huddersfield Contemporary Music Festival, and the Winnipeg New Music Festival.
