First performed at the Paris Opéra in 1802, Sémiramis by Charles-Simon Catel is an example of the revival at that time of the tragédie lyrique inherited from Gluck. A work with a touch of exoticism (Babylon), expressing the pathos of isolation, but also with pomp in its ambitious finales, the work bade farewell to the ‘Louis-XVI style’ and announced, in a neo-Classical style, the grand opéra of the Romantic period. But it came at a time of polemics between supporters and detractors of the new Paris Conservatoire, where Catel, at that time professor of harmony there, had made so many enemies that the audience pit at the Opera was bristling with vengeful hostility when the curtain rose on the first act…
Jean-Philippe Rameau (1683-1764) left two very different versions of his tragédie en musique Zoroastre: the first, in 1749, suffered from cabals and the work was withdrawn from the repertory. Rameau gave it a thoroughgoing revision in 1756. At this time, he was at the height of his powers. Melody, harmony, orchestration and choral writing no longer held any secrets for him. Zoroastre brought still further innovation. For the first time, he dispensed with a prologue, and turned the overture into a philosophical ‘programme’, the struggle between day and night, between good and evil. The 1749 version is entirely governed by avant-garde ideas; Zoroastre resembles Tamino in Die Zauberflöte, but two generations earlier. This disconcerted some of the audience: Zoroastre was a moral, social and philosophical opera.
