Requiem (Berlioz)

The Grande Messe des morts (or Requiem), Op. 5, by Hector Berlioz was composed in 1837. The Grande Messe des Morts is one of Berlioz's best-known works, with a tremendous orchestration of woodwind and brass instruments, including four antiphonal offstage brass ensembles placed at the corners of the concert stage. The work derives its text from the traditional Latin Requiem Mass. It has a duration of approximately ninety minutes, although there are faster recordings of under seventy-five minutes.

In 1837, Adrien de Gasparin, the Minister of the Interior of France, asked Berlioz to compose a Requiem Mass to remember soldiers who died in the Revolution of July 1830. Berlioz accepted the request, having already wanted to compose a large orchestral work. Meanwhile, the orchestra was growing in size and quality, and the use of woodwinds and brass was expanding due to the increasing ease of intonation afforded by modern instruments. Berlioz later wrote, "if I were threatened with the destruction of the whole of my works save one, I should crave mercy for the Messe des morts."

The premiere was conducted by François Antoine Habeneck on 5 December 1837 in commemoration of General Damrémont and the soldiers killed in the Siege of Constantine. In his autobiographical Mémoires, Berlioz claimed that Habeneck put down his baton during the dramatic Tuba mirum (part of the Dies irae movement) while he took a pinch of snuff, prompting the composer to rush to the podium to conduct the rest of the work himself, thereby saving the performance from disaster. The premiere was a complete success.
