Toward the end of his life, Berlioz wrote to a friend: "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 composer"s magnum opus is unrivaled in its grandeur, calling for huge orchestral and choral forces -- the original performance featured an assembly of 400 singers and players. From the brass fanfares of the "Day of Judgment" to the tender strains of "Agnus Dei," it is a work of pure celestial power. Berlioz"s undeniable importance to both music history and the evolution of the art of orchestration makes a thorough study of his work essential for scholars, musicians, and music students. Attractive and affordable, this new choral score is the ideal source book of the composer"s imaginative music.
