His work, particularly in pieces such as The Firebird, Petrushka, and The Rite of Spring, introduced unprecedented styles that revolutionized ballet music. Stravinsky combined elements of folk music and classical traditions, often utilizing startling rhythmic accents and dissonance to convey emotion and narrative. His ability to blend various musical influences opened new pathways in ballet and challenged traditional forms, making him a pivotal figure in early 20th-century music.
