The princess and her daughter have enjoyed playing the piece together at home, and as they performed, footage was shown of guests arriving for the carol service.
The Prince of Wales and Kate watched on as their children tied paper chains bearing their names on a "Connection Tree" outside the abbey.
Kate also narrated the letter that accompanied every order of service, where she reflected on the Christmas period that reminds us "how deeply our lives are woven together."
Despite life feeling "fragmented or uncertain" at times, she wrote the festive season "invites us to remember the power of reaching out to one another."
The mother and daughter could be seen smiling at each other throughout their performance.
It is understood Kate wanted to include the musical element in the carol service to highlight her belief in the importance of connections – as mentioned in her letter.
