I am waiting for the first comment to explore further!

I don't really know what you are trying to know.

Well, if you wish to understand the meaning, several standard dictionaries will provide it.

Cambridge Dictionary says: "a style of art, writing, music, theatre, and especially architecture popular in the West in the 1980s and 90s, that includes features from several different periods in the past or from the present and past."

Various sites also explain the word. One of them says:


Postmodernism can be seen as a reaction against the ideas and values of modernism, as well as a description of the period that followed modernism's dominance in cultural theory and practice in the early and middle decades of the twentieth century. The term is associated with scepticism, irony and philosophical critiques of the concepts of universal truths and objective reality. (Refer: https://www.tate.org.uk/art/art-terms/p/postmodernism)

There are several other sites that will elucidate the word.

Hope this is useful.

I agree you don’t need isms to appreciate a good book or a concert! This is more external than intrinsic aesthetics of the arts!
