Carols are festive songs traditionally sung during the Christmas season. They often celebrate themes of joy, peace, and goodwill, and can be performed by groups or individuals. Many carols have catchy melodies and are easy to sing, making them popular for gatherings and celebrations. The practice of singing carols dates back to the Middle Ages, with roots in both religious and secular traditions. While some carols focus on the birth of Jesus Christ, others highlight winter festivities. Today, caroling is a common activity, with people often going door-to-door to share music and cheer in their communities.
