Of humble origins, Franz Joseph Haydn was born in Rohrau, near Vienna, on 31 March 1732. When eight years old he was accepted into the choir school of Saint Stephen's Cathedral in Vienna, where he received his only formal education. Dismissed from the choir at the age of seventeen, when his voice broke, he spent the next several years as a struggling freelance musician. In 1755 Haydn was engaged briefly by Baron Karl Josef von Fürnberg, for whom he apparently composed his first string quartets. Haydn's marriage in 1760 to Maria Anna Keller proved to be unhappy. The turning point in Haydn's fortunes came in 1761, when he was appointed assistant music director to Prince Pál Antal Esterházy; a year later he became full director. As Kapellmeister, Haydn served under the patronage of thre

Of humble origins, Franz Joseph Haydn was born in the village of Rohrau, near Vienna, on March 31, 1732. When eight years old he was accepted into the choir school of Saint Stephen's Cathedral in Vienna, where he received his only formal education. Dismissed from the choir at the age of seventeen, when his voice broke, he spent the next several years as a struggling freelance musician. He studied on his own the standard textbooks on counterpoint and took occasional lessons from the noted Italian singing master and composer Nicola Porpora. In 1755 Haydn was engaged briefly by Baron Karl Josef von Fürnberg, for whom he apparently composed his first string quartets. Haydn's marriage in 1760 to Maria Anna Keller proved to be unhappy.
