Pie Iesu is a motet derived from the final couplet of the Dies Irae and often included in musical settings of the Requiem Mass. This short requiem lasting 35 minutes, it is written for orchestra, organ, mixed chorus and two soloists, soprano and baritone, and performed in Latin. It consists of seven movements; most famous is the central soprano aria Pie Jesu. It is possible that the reason for composing the Requiem was the death of composer's parents.
