Antonio Rosetti was probably born Anton Rös[s]ler in Litomeùrùice (Leitmeritz) about 1750. His first years are obscure, but in 1773 he had his first fixed employment in Wallerstein as livery servant and double bass player. From then onwards using only the Italian form of his name, he found there a court musical establishment of very good musicians, soon regarded as one of the best ensembles in Europe, as a number of reports witness, and one that in the 1780s had a gifted complement of some thirty players. Rosetti very soon began to compose symphonies, concertos and chamber music for the orchestra and its soloists, but also for employers elsewhere. Appointed Kapellmeister in 1785, he wrote chamber music especially for the woodwind and brass players of the court establishment, both the ever increasingly popular Harmoniemusik, music for wind ensemble, as well as for other instrumental combinations. Among these are, as far as we know, the earliest wind quintets in the history of music. His music retains elements of the Baroque in a generally classical idiom. Among his many concertos for wind instruments are fifteen for solo French horn and six for two horns.

With the death of the Kapellmeister Carl August Westenholz (1736-1789) at the court of the Duke of Mecklenburg-Schwerin in Ludwigslust, there arose a vacancy for which Rosetti applied, since he was suffering ill-health and was no longer happy with the material conditions of his work. As the Prince had great difficulty in financing his expensive musical establishment, Rosetti’s requests for an increase in his salary were in vain. He was given the position, which brought him three times his Wallerstein salary. Ludwigslust had an efficient court Kapelle of 29 distinguished musicians and a choir of twelve full-time court singers. It was here that Rosetti wrote, in addition to instrumental works, a number of splendid choral works. Meanwhile his reputation had spread throughout Europe, with performances of his compositions and often favourable comparison with those of Mozart or Haydn. A Requiem that he had written in 1776 in Wallerstein was performed in Prague nine days after the death of Mozart as a tribute to the latter, with 120 performers and an audience of four thousand. Rosetti was invited by Friedrich Wilhelm II of Prussia to Berlin, where he performed choral works, but returned ill and shortly afterwards, only 42 years old, he died, on 30th June 1792.
