Claude Debussy was a French composer whose innovations in harmony, texture, and form made him one of the most influential figures in Western music. Born Achille Claude Debussy in Saint-Germain-en-Laye in 1862, he studied at the Conservatoire de Paris and spent time as a household pianist for Tchaikovsky's patroness Nadezhda von Meck before establishing himself as a composer in Paris. His orchestral works, including Prelude a l'apres-midi d'un faune and La Mer, broke decisively with Germanic symphonic tradition, while his piano music, particularly the two books of Preludes and the suite Pour le piano, redefined the instrument's timbral possibilities. His opera Pelleas et Melisande remains a landmark of the genre. Debussy drew on influences ranging from Chopin and Wagner to Russian and East Asian music, synthesizing them into a harmonic language built on whole-tone scales, parallel chords, and unresolved dissonances that prioritized color and atmosphere over conventional resolution. His melodic material found new life in the jazz world through Larry Clinton's adaptation of Reverie into the popular song My Reverie, which became a hit in 1938 and has endured as a standard. Debussy died in Paris in 1918 at the age of fifty-five, leaving a body of work that fundamentally expanded the vocabulary available to composers who followed him.
