La favorite La Favorite (The Favourite, sometimes referred to by its Italian title: La favorita) is a grand opera in four acts by Gaetano Donizetti to a French-language libretto by Alphonse Royer and Gustave Vaëz, based on the play "Le comte de Comminges" by Baculard d'Arnaud. It premiered on December 2, 1840 at the Académie Royale de Musique (Salle Le Peletier) in Paris, France.
The Nutcracker and the Mouse King "The Nutcracker and the Mouse King" (German: "Nussknacker und Mausekönig" ) is a story written in 1816 by German author E. T. A. Hoffmann, in which young Marie Stahlbaum's favorite Christmas toy, the Nutcracker, comes alive and, after defeating the evil Mouse King in battle, whisks her away to a magical kingdom populated by dolls. In 1892, the Russian composer Pyotr Ilyich Tchaikovsky and choreographers Marius Petipa and Lev Ivanov turned Alexandre Dumas père's adaptation of the story into the ballet "The Nutcracker", which became one of Tchaikovsky's most famous compositions, and perhaps the most popular ballet in the world.
