Princess Charlotte duet with Kate Middleton branded 'favourite winter moment'

Kate Middleton and Princess Charlotte’s duet for Christmas carol is branded ‘lovely’ by the comprise.

Charlotte, who was seen playing Holm Sound, composed by Errand Cooper, worked out the instrument beautifully.

Speaking of the mother-daughter duo's "special bond", he said: "It was just lovely. I think I was there for a little bit of encouragement. I mean, imagine anybody performing a piece of music in front of a film crew, and then the person who wrote it. 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. It was a very special, sort of quiet moment. There's a power in reaching out to people, and that's what they did here."

Erland continued: "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. And there's a wonderful bit of serendipity as the piece was composed and dedicated to my mum, also called Charlotte, they didn't know about, that it's about motherhood, and how family plays such an important role and such a key part to all of this,” he added.

"The Princess and I both have a sort of shared love of music that celebrates the natural world and its rejuvenation and the wonder that you know that comes from it. There's so much joy and warmth and creativity and ideas surrounding those themes,” the expert noted.
