| 1. | Roman Catholic Church.

| 2. | any musical service, hymn, or dirge for the repose of the dead. |

In music, a Mass for one or more dead persons, containing biblical passages and prayers for the admission of the dead to heaven. The term has been loosely applied to other musical compositions in honor of the dead. A German Requiem by Johannes Brahms, for example, uses texts from the Bible but is not a Mass.
