Requiem for SATB choir and instruments. Although Rosenmüller didn't compose a requiem mass, he wrote music to be used in such a mass: an extensive setting of the "Dies irae" and settings of the "Kyrie" and "Agnus Dei". For the missing sections plain chant was included. In addition some pieces were performed which are linked to offices for the dead - in this case two penitental psalms: "Miserere mei Deus" (Ps 50/51) and "Domine ne in furore tuo" (Ps 6).
