Postmodern music emerged in the late 20th century as a reaction against the principles of modernism. It often blends different styles, genres, and cultural influences, creating a diverse soundscape. Composers like John Cage and Philip Glass are known for their experimental approaches, incorporating elements from popular music, classical traditions, and non-Western cultures. This genre frequently challenges traditional notions of structure and form, embracing randomness and improvisation. Postmodern music may also include the use of technology, such as sampling and electronic instruments, to create new auditory experiences. Overall, it reflects a more inclusive and eclectic perspective on music creation.
