Franz Joseph Haydn was an Austrian composer who kived during a period of March 31, 1732 – May 31, 1809. He was instrumental in the development of chamber music such as 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". He spent much of his career as a court musician for the wealthy Esterházy family.

Born January 27, 1756 in Salzburg Austria, Wolfgang Amadeus Mozart was a prolific and influential composer despite his short life ended on December 5, 1791 when he was only 35 years of age. He is among the greatest composers in the history of Western music, and his elder colleague Joseph Haydn wrote: "posterity will not see such a talent again in 100 years". His rapid pace of composition resulted in more than 800 works. Many of these compositions are acknowledged as pinnacles of the symphonic, concertante, chamber, operatic, and choral repertoire. The circumstances of his death are largely uncertain, and have thus been much mythologized..
