Overview
- Scottish composer Erland Cooper said he was invited to Windsor Castle for the filming and found the mother-daughter duo already polished, calling Princess Charlotte "very confident."
- The duet was recorded in Windsor Castle’s Inner Hall on December 5 and featured in ITV’s Christmas Eve broadcast rather than being performed live at Westminster Abbey.
- Kate played the left-hand part and 10-year-old Charlotte played the right-hand part for Cooper’s piece Holm Sound.
- Cooper said Holm Sound was written for his mother, also named Charlotte, and explores themes of motherhood and generational connection.
- Kensington Palace shared the segment on social media with a message about "love and connection through music," drawing warm reactions as coverage noted Charlotte’s ongoing piano lessons disclosed in 2023.
