A music, and even an entire world died with Richard Strauss (1864-1949). A sad swan song for a man who, from the age of twenty, reaped the laurels and the privileges that came with them. Though in many ways a bourgeois conformist, the composer was at one time—the era of the symphonic poems, and, above all, Elektra—a revolutionary in music. Then, with Der Rosenkavalier and Die Frau ohne Schatten, the former "man of the future" would make himself the champion of a lost cause: legacy. The legacy of Mozart in particular but Wagner too. Strauss would never stop exploring the magical world of theatre, making it more intelligible, more inhabitable, and more hospitable. Hofmannsthal and Zweig would be the privileged witnesses of this. A music and a world died with Strauss, and yet his work, which knew it would not be continued, is more alive within us than others who have followed on since and who imagine that they are starting something.
