“Princess Charlotte played beautifully, she really has a wonderful way of playing the lighter notes just beautifully. So we were able to celebrate in that together.
“It’s certainly one of my favourite winter solstice moments. To walk into the Castle, to be greeted by a Steinway grand piano, and then to have a really poignant recital and performance.”

How the Performance Came Together
Mr Cooper went on to describe his earlier conversations with Catherine and how the performance came about.
“We [him and Kate] had a very warm, creative conversation earlier in the year, which was lovely, and then it culminated with an invitation to Windsor Castle. The princess asked, ‘Would it be okay if we perform this piece of music that we so enjoy together?’
“It was such a lovely request, so I said absolutely no problem at all. I was invited to witness this incredible bond between mother and daughter performing together and for that I am so grateful.”
The Meaning Behind the Music
The composer explained that Holm Sound, which he wrote and dedicated to his mother—also named Charlotte—centres on themes of motherhood and the vital role family plays in life.
