During the Holy Triduum, the Church's morning and evening Liturgy of the Hours are traditionally prayed in darkness with extinguished candles (Tenebrae means "darkness"). In this richly symbolic office, she mourns the death of her Saviour with lamentations and sorrowful Psalms. At the end of the office, all the candles are extinguished. Psalm 50 ("Miserere Mei") is sung, and a loud noise ("strepitus") is made, symbolizing the darkness and earthquake following Christ's death.
