Modernist Music

On 29 May 1913, in Paris, the premiere of Le Sacre du Printemps — Stravinsky's music, Nijinsky's choreography — turned into a riot. The pounding, lopsided rhythms, the harmonies grinding against one another, the dancers stamping in deliberately ugly postures to enact a pagan sacrifice: it violated everything the audience expected of a ballet, and within minutes there were catcalls, then fistfights in the aisles, the dancers unable to hear the orchestra over the uproar. It became the most famous scandal in concert history — and a fitting overture, because what it announced was not a new style but the shattering of an old order. For three centuries Western music had been held together by tonality, the pull of every note toward a home key. Modernism is the story of what composers did once that pull let go.

Modernism was never one movement but a set of rival answers to a single question: once the key no longer holds a piece together, what does? The most radical answer was a new kind of order. Arnold Schoenberg, unable to keep writing in keys that no longer felt true, replaced tonality's natural gravity with an artificial law — the twelve-tone method, in which all twelve notes must sound in a fixed sequence before any may return, so that none can rule as home. His pupils Berg and Webern carried it to opposite extremes of lush drama and diamond compression, and after the war a younger generation extended the same ordering logic to rhythm and volume as well as pitch. Others found their coherence elsewhere. Igor Stravinsky, having detonated rhythm in the Rite, spent decades rebuilding from older models before adopting serial order himself. Béla Bartók turned to the folk music he had recorded across Eastern Europe by the thousands, fusing its modal scales and limping meters into taut modern structures like Music for Strings, Percussion, and Celesta. Then came the answers that gave up control altogether: John Cage let coins and the I Ching choose his notes, and in 4′33″ framed a silent room's ambient sound as music, suggesting that what holds a piece together might be nothing more than the frame we set around it. Ligeti dissolved melody and harmony into slowly shifting clouds of pure texture. And by the 1960s exhaustion with all this complexity produced its opposite — minimalism, which found unity in hypnotic repetition, simple patterns cycling and slowly phasing in the hands of Reich and Glass. One broken center; a half-century of incompatible ways to live without it.
