Franz Liszt, Hungarian Ferenc Liszt, (born Oct. 22, 1811, Raiding, Hung.—died July 31, 1886, Bayreuth, Ger.), Hungarian composer and pianist. Encouraged by his father, who was a talented amateur musician, Liszt developed an early interest in music and began composing at age eight.

He studied piano with Karl Czerny and composition with Antonio Salieri in Vienna, making his debut there in 1822. After a Paris success in 1823, he toured Europe, but his father’s early death (1828) and a disastrous love affair led to a desire to give up music for the priesthood. Hearing violinist Niccolò Paganini perform in 1831, Liszt was inspired to develop his own technique to the utmost and to compose his first mature pieces, including the Transcendental Études (1837) and Paganini Études (1839).

An affair with Countess Marie d’Agoult resulted in the birth of his daughter, Cosima (1837–1930), who would marry his friend, the composer Richard Wagner. Liszt’s brilliance and success were at their peak during the 1840s, when he toured Europe as a virtuoso, earning great adulation for his panache and his astounding technique. He ceased concertizing in the late 1840s to devote himself to composition and furthering the work of progressive composers.

In the 1850s he wrote many of his most ambitious works, including A Faust Symphony (1854) and the Piano Sonata in B Minor (1853). In 1865 he took minor Roman Catholic church orders, though he never became a priest. His later output is remarkable in anticipating many 20th-century developments; for instance, his development of chromatic harmony influenced atonal music.
