AFTERNOON AT THE OPERA: Rigoletto. The hunchbacked jester of the Duke of Mantua seeks revenge after the Duke seduces his daughter, but his attempt ends in disaster. First performed at the Teatro La Fenice in Venice in 1851, Rigoletto represented a watershed moment in the career of Giuseppe Verdi. By 1855, Rigoletto had been performed in Austria, Hungary, the Czech Republic, Germany, Russia, England, Spain, Greece, Portugal and New York City. Within the next two years he would follow Rigoletto with Il Trovatore and La Traviata, cementing his stature as the most important composer of Italian opera. Rigoletto combines some compelling musical-dramatic scenes (including father-daughter duets and a quartet) with some of the most famous tunes Verdi ever composed.
