Requiem (Verdi)
The Messa da Requiem by Giuseppe Verdi is a musical setting of the Roman Catholic funeral mass (Requiem) for four soloists, double choir and orchestra. It was composed in memory of Alessandro Manzoni, an Italian poet and novelist much admired by Verdi. The first performance in San Marco in Milan on 22 May 1874 marked the first anniversary of Manzoni's death. The work was at one time called the Manzoni Requiem. It is typically not performed in the liturgy, but in a concert of around 85–90 minutes.
