What is the most famous piece from Rigoletto?

La donna è mobile

Verdi's Rigoletto features one of opera's most recognizable arias: "La donna è mobile," sung by the Duke of Mantua. This memorable piece, whose title translates to "Woman is fickle," presents the Duke's cynical view of female constancy. The aria has become synonymous with the opera itself, despite—or perhaps because of—its controversial portrayal of women as inherently unreliable and changeable.
