Haydn and Mozart

Portraits of Haydn (left) and Mozart (right)

The composers Wolfgang Amadeus Mozart (1756–1791) and Joseph Haydn (1732–1809) were friends. Their relationship is not very well documented, but the evidence that they enjoyed each other's company is strong. Six string quartets by Mozart are dedicated to Haydn (K. 387, 421, 428, 458, 464, 465, the "Haydn" Quartets).
