 Some authorities have more or less equated postmodern music with the "contemporary music" composed well after 1930, from the late 20th century through to the early 21st century.Some of the diverse movements of the postmodern/contemporary era include the neoromantic, neomedieval, minimalist, and post minimalist.Contemporary classical music at the beginning of the 21st century was often considered to include all post-1945 musical forms.
