Completed in 1849, the "Te Deum", like the earlier and more famous "Grande Messe des Morts", is one of Berlioz's self-described "architectural" works. While the orchestral forces required are nowhere near as massive as huge as those for the Requiem, the work does call for a pipe organ which can compete on equal terms with the rest of the orchestra. It lasts approximately fifty minutes and derives its text from the traditional Latin Te Deum, although Berlioz made some changes to word order for dramatic purposes. The instrumental Prelude and Marche are seldom performed in concert. This new e-score has been created from the full score issued as part of the Berlioz complete works edited by Charles Malherbe and Felix Weingartner in 1900.
