What is new complexity?

New complexity, also known as post-complexity or the new complexity movement, is a movement in contemporary classical music that emerged in the early 1980s. It is characterized by complex, often highly detailed, and intricate compositions that challenge traditional notions of musical form and structure.

New complexity composers typically rely heavily on unconventional notation and extended instrumental techniques to achieve their unique sound. The music is often highly virtuosic and requires a high level of skill from performers.

The movement was largely a reaction against the minimalist and new simplicity movements that dominated classical music in the 1970s. New complexity instead favors a focus on intricate, multi-layered structures and complex interaction between disparate elements.

Some notable composers associated with new complexity include Brian Ferneyhough, Richard Barrett, Michael Finnissy, James Dillon, and Hilda Paredes. The movement has also had a significant influence on contemporary composers and performers outside of classical music, with its emphasis on complexity and intricacy inspiring new experimental approaches in a variety of different genres.
