Please answer the following question: Found the following article online, use it to answer the question: What did Carmen show on stage that broke new ground in the genre? Carmen (French pronunciation: [kamn]; Spanish: [kamen]) is an opera in four acts by French composer Georges Bizet. The libretto was written by Henri Meilhac and Ludovic Halevy, based on a novella of the same title by Prosper Merimee. The opera was first performed by the Opera-Comique in Paris on 3 March 1875, where its breaking of conventions shocked and scandalized its first audiences. Bizet died suddenly after the 33rd performance, unaware that the work would achieve international acclaim within the following ten years. Carmen has since become one of the most popular and frequently performed operas in the classical canon; the "Habanera" from act 1 and the "Toreador Song" from act 2 are among the best known of all operatic arias. The opera is written in the genre of opera comique with musical numbers separated by dialogue. It is set in southern Spain and tells the story of the downfall of Don Jose, a naive soldier who is seduced by the wiles of the fiery gypsy Carmen. Jose abandons his childhood sweetheart and deserts from his military duties, yet loses Carmen's love to the glamorous torero Escamillo, after which Jose kills her in a jealous rage. The depictions of proletarian life, immorality, and lawlessness, and the tragic death of the main character on stage, broke new ground in French opera and were highly controversial. After the premiere, most reviews were critical, and the French public was generally indifferent. Carmen initially gained its reputation through a series of productions outside France, and was not revived in Paris until 1883. Thereafter, it rapidly acquired popularity at home and abroad. Later commentators have asserted that Carmen forms the bridge between the tradition of opera comique and the realism or verismo that characterised late 19th-century Italian opera. The music of Carmen has since been widely acclaimed for brilliance of melody, harmony, atmosphere, and orchestration, and for the skill with which Bizet musically represented the emotions and suffering of his characters....
