Béla Bartók (1881-1945), the great Hungarian composer, was one of the most significant musicians of the twentieth century. He shared with his friend Zoltán Kodály, another leading Hungarian composer, a passion for ethnomusicology. His music was invigorated by the themes, modes, and rhythmic patterns of the Hungarian and other folk music traditions he studied, which he synthesized with influences from his contemporaries into his own distinctive style.
