Grand Opéra is a style of opera that emerged in France during the 19th century, characterized by its grand scale and elaborate productions. It typically features large orchestras, extensive choruses, and spectacular staging, often incorporating ballet and dramatic visual effects. The stories are usually set in historical or mythical contexts, emphasizing themes of love, tragedy, and heroism. The most famous composer associated with Grand Opéra is Giacomo Meyerbeer, whose works like "Les Huguenots" and "Robert le Diable" exemplify the genre's opulence. This style influenced the development of opera in other countries and laid the groundwork for later theatrical forms, including musical theatre.
