Opéra féerie Opéra féerie (plural: "opéras féeries ") is a French genre of opera or opéra-ballet, often with elements of magic in their stories. Popular in the 18th century, from the time of Jean-Philippe Rameau onwards, the form reached its culmination with works such as "La belle au bois dormant" by Michele Carafa and "Cendrillon" by Nicolas Isouard at the beginning of the 19th century.
