As a transitional composer, between the late Italian Baroque and early Classical forms, Mancini composed in a number of different genres including operas, cantatas, liturgical works, oratorios, seranatas, motets, masses, psalms, and instrumental solos for the violin and harpsichord. Though he vied for positions in the Neapolitan court, particularly after Scarlatti's position was declared vacant, and through the tension-filled political times of the wars of Spanish-Austrian succession, Mancini did not successfully serve the court until 1707. Nevertheless, he did hold less important positions at the court for some years. Even this, however, was temporary for Scarlatti returned to Naples. Mancini was the director of the Conservatory at Saint Maria di Loreto from 1720 until his death. Compositionally he used the basso continuo and counterpoint as in the Baroque style but employed the extension and development of phrases found in the Classical style. Of his many operas, a minimum of nineteen were initially performed in Naples and Mancini was quite poplar because these compositions. ~ Keith Johnson, Rovi
