Some of the most well-known Christmas carols include "Silent Night," "Jingle Bells," "The First Noel," "Away in a Manger," and "O Holy Night." Christmas carols are often sung in churches, schools, and community events during the holiday season. They are also frequently performed by choirs and solo singers.
