Franz Joseph Haydn was an Austrian composer of the Classical period. He was pivotal in the evolution of chamber music forms like the string quartet and piano trio. His contributions to musical form have led him to be called "Father of the Symphony" and "Father of the String quartet".
Haydn arose from humble origins, the child of working people in a rural village. He established his career first by serving as a chorister at St. Stephen's Cathedral, Vienna, then through an arduous period as a freelance musician. Eventually he found career success, spending much of his working life as music director for the wealthy Esterházy family at their palace of Eszterháza in rural Hungary.
