Tenebrae, meaning ‘shadows’ or ‘darkness,’ is a sung, contemplative, candlelit service of ancient midnight prayers from the monastic tradition of the Middle Ages. This sung liturgy consists of chanted Psalms, lessons, and passages from the Lamentations of Jeremiah. As each psalm is sung, a candle is extinguished and the Cathedral Church darkens until only one candle remains. The King’s Chapel Choir sings plainchant psalms and Thomas Tallis’ setting of the Lamentations of Jeremiah. Concludes with the quiet recitation of Psalm 51 in darkness. This service makes no demands on those in attendance other than attentiveness. All welcome.
