Don Juan (Strauss) in the context of "Don Juan"

In music, modernism is an aesthetic stance underlying the period of change and development in musical language that occurred around the turn of the 20th century, a period of diverse reactions in challenging and reinterpreting older categories of music, innovations that led to new ways of organizing and approaching aspects of music such as harmony, melody, sound, and rhythm, and changes in aesthetic worldviews in close relation to the larger identifiable period of modernism in the arts of the time. The operative word most associated with it is "innovation". Its leading feature is a "linguistic plurality", which is to say that no one musical language, or modernist style, ever assumed a dominant position.

Examples include the celebration of Arnold Schoenberg's rejection of tonality in chromatic post-tonal and twelve-tone works and Igor Stravinsky's move away from symmetrical rhythm.

Richard Georg Strauss (/straʊs/; German: [ˈʁɪçaʁt ˈʃtʁaʊs] ; 11 June 1864 – 8 September 1949) was a German composer and conductor known for his tone poems and operas. A leading figure of the late Romantic and early Modern era, and a successor to Richard Wagner and Franz Liszt, he combined, along with his friend Gustav Mahler, subtleties of orchestration with an advanced harmonic style.

His compositional output began in 1870 when he was just six years old and lasted until his death nearly eighty years later. His first tone poem to achieve wide acclaim was Don Juan, and this was followed by other lauded works of this kind, including Death and Transfiguration, Till Eulenspiegel's Merry Pranks, Also sprach Zarathustra, Don Quixote, Ein Heldenleben, Symphonia Domestica, and An Alpine Symphony. His first opera to achieve international fame was Salome, which used a libretto by Hedwig Lachmann that was a German translation of the French play Salomé by Oscar Wilde. This was followed by several critically acclaimed operas with librettist Hugo von Hofmannsthal: Elektra, Der Rosenkavalier, Ariadne auf Naxos, Die Frau ohne Schatten, Die ägyptische Helena, and Arabella. His last operas, Daphne, Friedenstag, Die Liebe der Danae and Capriccio used libretti written by Joseph Gregor, the Viennese theatre historian. Other well-known works by Strauss include two symphonies, lieder (especially the Four Last Songs), the Violin Concerto in D minor, the Horn Concerto No. 1, Horn Concerto No. 2, his Oboe Concerto and other instrumental works such as Metamorphosen.

Ein Heldenleben (A Hero's Life), Op. 40, is a tone poem by Richard Strauss. The work was completed in 1898. It was his eighth work in the genre, and exceeded any of its predecessors in its orchestral demands. Generally agreed to be autobiographical in nature despite contradictory statements on the matter by the composer, the work contains more than thirty quotations from Strauss's earlier works, including Also sprach Zarathustra, Till Eulenspiegel, Don Quixote, Don Juan, and Death and Transfiguration.
