Katherine Jenkins visits Pembroke College Chapel in Cambridge to explore the sacred sound of the church organ and to meet organist virtuoso and star of the Proms, Anna Lapwood. Anna demonstrates the chapel’s 17th-century organ and the rich variety of sound at the fingertips of the player, creating the perfect sound for worship. Katherine discovers the history behind the instrument, when it first entered churches and cathedrals across Europe, and how it influenced and defined church music. A choir directed by Anna at Pembroke College performs for Katherine, and we hear what they love about singing with the organ and how it brings them closer to God.
