 The opening night was a complete triumph, especially the "scena drammatica" and the Duke's cynical aria, "La donna è mobile", which was sung in the streets the next morning (Verdi had maximised the aria's impact by only revealing it to the cast and orchestra a few hours before the premiere, and forbidding them to sing, whistle or even think of the melody outside of the theatre).Many years later, Giulia Cora Varesi, the daughter of Felice Varesi (the original Rigoletto), described her father's performance at the premiere.Varesi was very uncomfortable with the false hump he had to wear; he was so uncertain that, even though he was quite an experienced singer, he had a panic attack when it was his turn to enter the stage.
