The great thing about Christmas is that you know lots of good things will happen. You know that pretty lights will start popping up all over the place. You know you'll get a holiday from school. You're probably ready to eat a special meal and to see family and friends. All these things are part of what we call a tradition. Christmas is a big tradition - it celebrates the birth of Jesus. People who want to celebrate this do it in different ways. But whatever happens, there is always music!

Can you imagine Christmas without music? Part of the fun is hearing things that are only played at Christmas and at no other time of year - carols that make you think of the end of term, or the holidays, or bobble hats; songs that make you think of food, or snow, or stockings. Here are some of the most popular carols, as well as some other surprises... Merry Christmas!
