[4] Following the death of Antonio Caldara in December 1736, Johann Fux (at the time Kapellmeister to Charles VI), invited Predieri to Vienna to serve as his assistant.
During his time in Vienna he composed several more operas, often performed to mark special occasions at the imperial court, two oratorios, a Stabat Mater, and many other pieces of sacred music.
According to musicologist Anne Schnoebelen, Predieri's sacred music demonstrated his "mastery of vocal polyphony and polychoral writing" while the operas he composed in Vienna to texts by Metastasio and Giovanni Pasquini were marked by carefully set recitatives and arias with impressive dynamic colouring.
In common with those of his predecessors at the court, Fux and Caldara, Predieri's Viennese operas and oratorios contained what Trevor Herbert has described as "spectacular high trumpet parts surpassing all others anywhere in terms of range and technical difficulty.
[15] Two of Predieri's Lamentations for solo voice and basso continuo can heard on Baroque Nocturnes For The Liturgy Of Holy Week performed by the La Flora ensemble (Bongiovanni Records).
"Pace una volta", an aria for soprano and solo trumpet from his opera Zenobia was recorded by Kathleen Battle and Wynton Marsalis on their album Baroque Duet (Sony Classical).
