Giuditta is an operatic musikalische Komödie (German for musical comedy) in five scenes, with music by Franz Lehár and a German libretto, by Paul Knepler and Fritz Löhner-Beda. Scored for a large orchestra, it was Lehár's last and most ambitious work, written on a larger scale than his previous operettas. Of all his works it is the one which most approaches true opera, the resemblances between the story and that of Bizet's Carmen and its unhappy ending heightening the resonances. Perhaps the best known song in the work is the soprano aria "Meine Lippen, sie küssen so heiß", sung by Giuditta in the fourth scene. Another strong influence, especially for the North African setting, was the 1930 movie Morocco, starring Marlene Dietrich and Gary Cooper in very similar central roles, she being a singer-dancer, he being a soldier.
The work received its first performance at the Vienna State Opera on 20 January 1934, with Jarmila Novotná and Richard Tauber in the leading roles. The premiere attracted more attention than any of his previous works. It was broadcast live on 120 radio stations across Europe and the United States and ran for 42 performances in its debut season. Despite this initial interest, Giuditta soon faded from the repertoire, more completely than any of Lehár's other works.
The original production, directed by Hubert Marischka, played 42 times during the season in which it was introduced into the general Vienna opera repertoire. In 1938, after only a few more performances had been played, came the Anschluss and Tauber left town, as did Novotná. Librettist Fritz Löhner-Beda was taken away to a concentration camp and died in Auschwitz.
