SUMMARY
Do the terms “modernism” and “postmodernism” objectively characterize the trends in the music history of the 20th century or are they merely theoretical abstractions? How can they be applied to the music history of specific countries, for example, when analysing a local historical experience? The article will consider these questions primarily to focus on the representation of the modernist and postmodernist aesthetics in the stylistic developments of the 20th-century Latvian music history.
