Igor Stravinsky (1882–1971) was a Russian-born composer whose innovative works profoundly influenced 20th-century music. Initially trained under Nikolai Rimsky-Korsakov, Stravinsky gained international acclaim with ballets like "The Firebird" (1910), "Petrushka" (1911), and the groundbreaking "The Rite of Spring" (1913), which challenged traditional rhythmic structures. His compositional style evolved through distinct periods: the Russian period, marked by folk influences; the neoclassical period, reflecting a return to classical forms; and the serial period, embracing twelve-tone techniques. Stravinsky's adaptability and originality cemented his status as a pivotal figure in modernist music. ([britannica.com](https://www.britannica.com/biography/Igor-Stravinsky?utm_source=openai))
