Luigia arrived at the Esterházy court with her husband Antonio in 1779; both had two-year contracts. Luigia was nineteen years old at the time. Polzelli soon turned out not to be a particularly able singer. Moreover, her husband had difficulties in fulfilling his duties as a violinist, as he was in the initial stages of a long drawn out demise from tuberculosis. The reigning prince, Nikolaus Esterházy, was a great connoisseur of opera who was well acquainted with high-quality singing, and recognizing Luigia's mediocrity and Antonio's unreliability he soon moved (1780) to have them dismissed (in fact, he was willing to buy out the rest of their contracts). However, at this time it emerged that Polzelli had become the lover of Haydn, then 48, who had had a very bad relationship with his wife almost since the beginning of their marriage. The Prince, who valued Haydn's services immensely, apparently agreed to keep the Polzellis on the payroll.
