Attila (opera) Attila is an opera in a prologue and three acts by Giuseppe Verdi to an Italian libretto by Temistocle Solera, based on the 1809 play Attila, KÃ¶nig der Hunnen (Attila, King of the Huns) by Zacharias Werner. The opera received its first performance at La Fenice in Venice on 17 March 1846.
Details from Bill Alford: Orff wrote a secular cantata, titled Carmina Burana based on the poems from the manuscript, but did not use any of the original melodies. The poems comprise religious, political, moral, erotic, Bacchic and Satirical verses. When Orff discovered the Carmina Burana for himself, the poems changed his entire career. He was past forty years old and more prominent in his native Munich as a music educator than a composer. In writing Carmina Burana, he found his own, unmistakable style.
