This piece is The Kyrie Eleison, from the Gregorian Chant setting Missa Orbis Factor, commonly referred to as Mass XI for Ordinary Sundays.

Missa Orbis Factor is a plainsong mass, designed to be sung in unison and a cappella. This arrangement attempts to keep the essential character of the Mass, whilst providing a harmonically simple modern setting.

The composer is unknown, the tune was probably based on a devotional hymn “Orbis factor, rex aeternae eleison” (“Creator of the world, Eternal King, have mercy”).

This is usually sung during lent due to its melancholic tone which is suitable for the penitential season.
