What is the Aria of opera La Donna e mobile?

La donna è mobile (Italian pronunciation: [la ˈdɔnna è ˈmɔːbile]), meaning The woman is fickle, is an aria for tenor from Act III, Scene 5, of Giuseppe Verdi's opera Rigoletto, first performed in 1851. Rigoletto was one of the first examples of the Italian composer's "middle period". Its libretto was adapted from Victor Hugo's 1832 play Le roi s'amuse. Verdi was initially reluctant to set the story because of its lack of a positive outcome. Hugo gave permission only on condition that the characters' names and locale be changed
