Joseph Haydn

Austrian composer of the Classical period, born 1732-03-31 or 1732-04-01 in Rohrau, died 1809-09-05 in Vienna, Austria.
He brings the "sonata form" to a very high degree of improvement.
His symphonies and his string quartets (forms of which he is considered "the father") have become highly inspirational style models.
Haydn made a fundamental contribution to the development of chamber music; thanks to the numerous quartets, trios for piano, for strings and also with the unusual trios for baryton, viola and cello.
