First work: He was, in Ferrara, among the founders of the Accademia degli Intrepidi, in which he participated with the name of Aggiunto and for which he composed the Filli diSciro, a pastoral fable probably performed in 1605 and published in 1607 by the academics.
The Filli di Sciro is a pastoral fable with a complex plot and yet developed with notable constructive skill around a double action: that of Celia's contemporary and equal love for two shepherds , Nisus and Amyntas, who had saved her from the dangers of a centaur, both of whom were injured, and that of the two children Phyllis and Thyrsis, sent as hostages to the king of Thrace.


II work: As an author of lyrics for music, Salvadori contributed to the evolution of the new style of theatrical singing. From the classical mythological repertoire, which Ottavio Rinuccini and Iacopo Corsi had drawn upon, he moved on to the elaboration of the chivalric one, of predominantly Ariostesque origin, in vogue since the second decade of the century in the operatic entertainments of various courts in central-northern Italy. Finally, he created an unprecedented sacred and hagiographic variant of the genre, a harbinger of subsequent developments. Characteristic of his production, whether epic or religious in subject, was the use of comic inserts.
