In the last days of April 1782, Rosetti packed his belongings and started on the long journey back to Wallerstein. He must have done this with some conflicting emotions. Paris had been a musical oasis that he would certainly miss. On the other hand, he had not seen his wife and children for a long time. By the middle of May Rosetti was back in Wallerstein. He quickly reentered life there, resuming his musical responsibilities and renewing friendships with his colleagues in the Hofkapelle.

During Rosetti's seven-month absence from court, a number of changes had occurred in the Hofkapelle. Of special musical significance was a new and even more pronounced cultivation of the music of Haydn. Kraft Ernst had long admired Haydn's music, and even in the 1770s the court music collection included a number of symphonies by the Esterházy Kapellmeister. With the restructuring of his Kapelle the prince renewed this interest and tried to assemble a full library of Haydn's symphonies. Haydn must have been aware of the prince's interest in his works. As has already been mentioned, in December 1781—just about the time that Rosetti reached Paris—Kraft Ernst received a letter from the Haydn offering him six new string quartets at a special subscription price of 6 ducats. This initiated a correspondence between the prince, his Viennese agents, and Haydn that lasted for a decade.
