Allegri's Miserere is one of the most famous and beautiful pieces of sacred music ever composed. Drawing from King David's lament in Psalm 50, it is a composition of great sorrow and an appeal to God's mercy: poignant at any season of Life, but especially during Lent. It explores the beauty and emotion of penance and the mystery of conversion. In this video, Fr. Edmund walks us through Allegri's technical mastery in the music, its important liturgical context, and its enduring relevance for our lives and the life of the whole Church.
