Modernism in Poetry

Most serious poetry today is still Modernist. Modernism in literature is not easily summarised, but the key elements are experimentation, anti-realism, individualism and a stress on the cerebral rather than emotive aspects.
Discussion
Modernist writing is challenging, which makes it suitable for academic study. Many poets come from university, moreover, and set sail by Modernism's charts, so that its assumptions need to be understood to appreciate their work. And since Postmodernism still seems brash and arbitrary, writing in some form of Modernism is probably the best way of getting your work into the better literary magazines. How much should you know of its methods and assumptions?
You need to read widely — poetry, criticism and literary theory. Modernism was a complex and diverse movement. From Symbolism it took allusiveness in style and an interest in rarefied mental states. From Realism it borrowed an urban setting, and a willingness to break taboos. And from Romanticism came an artist-centred view, and retreat into irrationalism and hallucinations.
Hence many problems. No one wants to denigrate the best that has been written this last hundred years, but the forward-looking poet should be aware of its limitations. Novelty for novelty's sake ends in boredom and indifference, in movements prey to fashion and media hype. Modernism's ruthless self-promotion has also created intellectual castes that carefully guard their status. Often the work is excessively cerebral, an art-for-art's sake movement that has become faddish and analytical. The foundations tend to be self-authenticating — Freudian psychiatry, verbal cleverness, individualism run riot, anti-realism, overemphasis on the irrational. These concepts may not be wholly fraudulent, but as articles of faith they have not won general assent. Modernist work will give you accredited status, but possibly neither an avant-garde reputation nor wide popularity.
Suggestions
1. Modernist work is often the most accessible of today's poetry, thanks to education, public libraries and a vast critical industry. Start therefore with Yeats, Frost, Pound, Eliot, Stevens, Williams, etc., and follow your interests — back into traditional poetry or forward into Postmodernist styles.
2. Model your first efforts on the better poems of Modernism. You will learn much about the poet's craft, and produce work that is still acceptable to the better poetry magazines.

3. Read the biographies of Modernist artists to understand how and why they made their innovations. Then read aesthetics and nineteenth-century continental philosophy to get a broader view of the matter.
