Béla Bartók is most famous for his piano compositions which included the Sonata for Two Pianos and percussion (1937), the Violin Concerto No. 2 (1938), the Piano Concertos No. 1 and No. 2, and the Music for Strings, Percussion and Celesta (1936).

Raised as a Catholic, by his early adulthood Bartók had become an atheist. He later became attracted to Unitarianism and publicly converted to the Unitarian faith in 1916.

Bartók's style in his art music compositions was a synthesis of folk music, classicism, and modernism. His melodic and harmonic sense was profoundly influenced by the folk music of Hungary, Romania, and other nations.

How many songs did Bela Bartok compose? Bartok, in collaboration with Zoltán Kodály, transcribed over 10,000 folk songs from Hungary, Slovakia, Romania and Bulgaria. He also composed 74 works of his own.
