Three hundred children joined Durham Cathedral choir to fill the historic space with music as part of the Durham Cathedral Music Outreach Celebration.
The event on Wednesday was part of a regular special celebration and was watched by families, friends and visitors.
The children - who were joined for the triannual event by choristers from Durham Cathedral choir - came from 10 primary schools across County Durham, from the coast to the edge of the Durham Dales: Belmont Church of England; Coxhoe; Prince Bishops Community; Witton Gilbert; Blackhall; Escomb; Shotton Hall; Cleves Cross Academy; Green Land Church of England and St Joseph's Catholic.
Each school taking part in the Durham Cathedral Music Outreach Celebration had received support and tuition over the past term from Daniel Cook, master of the choristers and organist of Durham Cathedral, and the cathedral choristers, to ensure they were prepared for the big day.
Daniel Cook said: "The choristers of Durham Cathedral Choir perform daily, alongside the gentlemen and choral scholars, as part of regular cathedral services and special events, keeping centuries of musical tradition alive. The choristers enjoy nothing more than sharing their skills and passion for music with like-minded school children during these jubilant music outreach celebrations.
"It was clear that the children had worked incredibly hard over the school term to deliver such a rousing performance, providing their family and friends with lasting memories to treasure."
The Durham Cathedral Music Outreach Celebration included Howard Goodall's setting of The Lord is my Shepherd, made famous as the signature tune for television programme The Vicar of Dibley. There was also a rendition of Danny Boy, and a demonstration of the cathedral organ by Daniel Cook that included an impersonation of a train.
The Durham Cathedral Choristers sang Peter Hurford's Litany to the Holy Spirit, and the celebration concluded with Jonah-man Jazz – Michael Hurd's telling of the story of Jonah and the Whale, with narration by Canon Michael Hampel.
