La Valse, M. 72

Completed in 1920 and premiered on 12 December 1920 by the Lamoureux Orchestra under Camille Chevillard, La Valse began as a tribute to Johann Strauss II and the opulent world of the Viennese waltz but evolved into something far more ambiguous and disturbing. Ravel described it as a 'fantastic and fatal whirling,' in which 'through whirling clouds, waltzing couples may be faintly distinguished.' The work opens with deep-register murmurings that gradually coalesce into the waltz rhythm, reaches a moment of glittering ballroom splendour, then accelerates into increasingly fragmented, violent disintegration — a portrait many hear as elegiac of the pre-war European civilisation shattered by 1914-18. Stravinsky and Diaghilev famously rejected it as a masterpiece but not a ballet. La Valse remains one of the most technically exacting pieces for professional orchestra, demanding absolute precision of ensemble across its escalating rhythmic complexity.
