21 Greatest Composers of the 20th Century Who Changed Modern Classical Music

These composers played pivotal roles in shaping the music of the 20th century, each bringing their unique voice to the evolution of classical music.

Here’s a list of 21 of the greatest 20th-century composers, known for their significant contributions to classical music and its evolution:

#1 Igor Stravinsky

Igor Stravinsky, born in 1882 in Russia, is one of the most influential composers of the 20th century, known for his innovative approach to rhythm, harmony, and orchestration. Stravinsky first gained international fame with his ballets The Firebird (1910), Petrushka (1911), and most notably The Rite of Spring (1913), whose premiere caused a near-riot due to its avant-garde dissonance and complex rhythms. This work marked a turning point in classical music, pushing the boundaries of traditional compositional techniques and influencing countless composers.

Throughout his career, Stravinsky continually reinvented his style, moving from Russian nationalism to neoclassicism and later exploring serialism. His adaptability and willingness to embrace new ideas made him a central figure in 20th-century music, leaving a lasting legacy that continues to resonate in contemporary classical music.

#2 Arnold Schoenberg

Arnold Schoenberg, born in 1874 in Austria, was a pioneering composer who revolutionized 20th-century music by developing the twelve-tone technique, a method that eschews traditional tonality in favor of a more structured, yet atonal approach. Schoenberg’s early works, such as Verklärte Nacht (1899), are rooted in late-Romanticism, but he soon moved towards atonality, as evidenced in Pierrot Lunaire (1912), a groundbreaking work that blends speech and song in a unique, expressionist style.

Schoenberg’s twelve-tone method, first fully realized in works like his Suite for Piano (1921–23), became one of the most influential compositional techniques of the 20th century. His impact on music theory and composition is immense, shaping the course of modern music and influencing generations of composers who followed.

Bartók’s music often features bold harmonies, intricate rhythms, and a deep connection to the folk traditions of his homeland. His contributions to ethnomusicology and his ability to synthesize folk elements with classical forms have made him one of the most important and influential composers of the 20th century.
