Haydn began his musical education in 1741 as a choirboy in the Vienna cathedral, possibly under Fux (who died the following year). When his voice changed young Haydn accompanied Porpora's voice students, thus, inadvertently, becoming Porpora's student as well. In 1761, after a three-year appointment at Lukavec, Haydn became Kapellmeister to the Esterhàzy family, which position he maintained to the end of his life. Between 1790 and 1795 Haydn made two acclaimed trips to London, where he briefly taught Beethoven. Haydn's works include more than 104 symphonies, concertos, operas, oratorios, Masses, and numerous chamber works.
