Passage: As a "house officer" in the Esterházy establishment, Haydn wore livery and followed the family as they moved among their various palaces, most importantly the family's ancestral seat Schloss Esterházy in Eisenstadt and later on Esterháza, a grand new palace built in rural Hungary in the 1760s. Haydn had a huge range of responsibilities, including composition, running the orchestra, playing chamber music for and with his patrons, and eventually the mounting of operatic productions. Despite this backbreaking workload, the job was in artistic terms a superb opportunity for Haydn. The Esterházy princes (Paul Anton, then from 1762–1790 Nikolaus I) were musical connoisseurs who appreciated his work and gave him daily access to his own small orchestra. During the nearly thirty years that Haydn worked at the Esterházy court, he produced a flood of compositions, and his musical style continued to develop.
