Daniel-François-Esprit Auber (1782-1871), the most amiable French composer of the nineteenth century, came to his abilities late in life. After a stalled commercial career, he studied with Cherubini. His first works were not a success, but La Bergère Châteleine (1820), written at the age of 38, established him as an operatic composer. He then met the librettist Eugène Scribe (1791-1861), with whom he developed a working partnership, one of the most successful in musical history, that lasted until Scribe's death. After Le Maçon (1825) and La Muette de Portici (1828), Auber's life was filled with success. In 1829 he was appointed a member of the Institut, in 1839 Director of Concerts at Court, in 1842 Director of the Conservatoire, in 1852 Musical Director of the Imperial Chapel, and in 1861 Grand Officer of the Légion d'Honneur. Les Chaperons blancs is one of Auber's least known operas, falling between Le Cheval de bronze (1835) and Le Domino noir (1837), two of his most famous works. The première also took place only five weeks after that of Meyerbeer's celebrated Les Huguenots (29 February 1836) had carried all before it. Like the latter, Auber's opera is centred around a theme of political conspiracy, although obviously observed through the lighter lens of the comique style. The tradition of the rescue opera, popular since the French Revolution, also features in the storyline, as does the motif of apparent death through soporifics so memorably used by Shakespeare in Romeo and Juliet (c. 1594). The leading characters were created by two great stars of the Opéra-Comique, Jean-Baptiste-Marie Chollet and Geneviève-Aimeé-Zoé Prévost, both of whom had brought to life the leading roles in Auber's most famous comic creation, Fra Diavolo (1830).This book presents an insight into the life and work of Auber by close examination of this little-known opera, with consideration of origins, casting, and plot, and analysis of dramaturgy, musical style, and reception history. This volume provides the vocal/piano score of Les Chaperons blancs, preceded by an introduction to the life and work of Auber, and a reading of the opera. There are examples from the score, prints from contemporary sources and other theatrical memorabilia, adding an important iconographical aspect to the general place and relevance of this work in nineteenth-century French operatic culture.
