Jean-Philippe Rameau was a French composer and music theorist. Regarded as one of the most important French composers and music theorists of the 18th century, he replaced Jean-Baptiste Lully as the dominant composer of French opera and is also considered the leading French composer of his time for the harpsichord, alongside François Couperin.

French opera is both the art of opera in France and opera in the French language. It is one of Europe's most important operatic traditions, containing works by composers of the stature of Rameau, Berlioz, Gounod, Bizet, Massenet, Debussy, Ravel, Poulenc and Messiaen. Many foreign-born composers have played a part in the French tradition, including Lully, Gluck, Salieri, Cherubini, Spontini, Meyerbeer, Rossini, Donizetti, Verdi and Offenbach.
