12 newly-commissioned pieces of music, including one by Andrew Lloyd Webber, will be played during King Charles' coronation service.
The King personally selected the music for the ceremony on May 6 at Westminster Abbey.
According to Lord Lloyd-Webber, the new coronation anthem should reflect a "joyful occasion.".
In honor of the King's father, Prince Philip, a gospel choir and Greek Orthodox music will perform.
With compositions by classical musicians like William Byrd, George Handel, and Sir Edward Elgar, the music will have a traditional feel.

The Queen Consort Camilla, who this week tested positive for Covid, will be crowned alongside the King.

With her announcement last week that her crown would not contain the Koh-i-Noor diamond, whose ownership has been in dispute, Camilla has managed to allay concerns about the crown she will be donning.
Six orchestral works, five choral compositions, and an organ piece will all be included in the new coronation music.
O sing unto the Lord a new song; for he has done marvellous things. That is the opening line of an anthem that Lord Lloyd-Webber is writing based on the biblical text of Psalm 98. ".
Like the King, the composer and theater owner is 74 years old. He has a long history of writing well-known musicals like Cats and The Phantom of the Opera.
Lord Lloyd-Webber, who left the House of Lords in 2017, has advocated for the arts and music.

Choristers from Westminster School will sing the Latin call "Vivat" at the moment the King is acclaimed, just as they did for earlier coronations, including that of the late Queen in 1953.
Westminster Abbey, where new music for her funeral was commissioned last September, will host the coronation service.
Some of that music was created on demand from composers who were approached many years prior, such as Sir James MacMillan, who was asked to compose a piece of choral music in secret in 2011.
The composer first heard the song performed while watching the historic funeral on television because he was unable to attend rehearsals.
King Charles' coronation will feature music, and a concert with world-famous headliners will be held the following night at Windsor Castle.
