Highgate composer Debbie Wiseman says it's "an immense honour" to write music for King Charles III's coronation.
Wiseman, who was also musical director of The Queen's Platinum Jubilee celebration at Windsor, is among 12 composers chosen to create new work for the ceremony in Westminster Abbey.
She has penned a piece for the Abbey's choir and organist, and a second for hand-picked gospel singers The Ascension Choir, who also performed at Harry and Megan's wedding.
Other new works include an anthem by Sir Andrew Lloyd Webber, and a coronation march by Patrick Doyle. The film and TV composer, whose work ranges from Wolf Hall to Wilde, said the King himself was closely involved in choosing music for the May 6 ceremony.
"It's just thrilling," she said. "It really is an immense honour. Many of us, myself included, haven't experienced a coronation in our lifetime, and it's really something to celebrate.
"The King has shaped the programme very much to his personal taste which goes across all genres, from theatre and film, to classical and contemporary. It marries the modern with the traditional, well-loved composers like Vaughan Williams and Hubert Parrry. To have 12 brand new commissions is hugely important and shows the King's passion for music and the arts. That he has taken the trouble to create this extraordinary amount of diverse music, that brings almost every corner of musical culture together in one place, is very exciting."
Wiseman previously met the King when he awarded her an OBE in 2018, and after the Queen's Platinum Jubilee celebrations last May.
"I had the huge privilege of being the musical director and composer at what was the Queen's final large engagement. Everything about it was designed to be things that she enjoyed, and she really loved it."
Writing for the Coronation's 2,000 guests and a live TV audience of millions she says "you can't think about the number of people who will be watching."
"Whenever I write a piece of music whether for one person or a 100 million, I think about who it is for, and where it's going to be performed. The Diamond Jubilee pageant was on a barge across the Thames so I wrote lots of brass instruments they would travel across water.
"The Abbey has a huge generous acoustic, and what was going through my mind when I was sitting at a piano and writing was to create a celebratory atmosphere and joyful feeling. Then when the performers sing it, it will come to life."
