Christmas music comprises a variety of genres of music regularly performed or heard around the Christmas season. Music associated with Christmas may be purely instrumental, or in the case of carols, may employ lyrics about the nativity of Jesus Christ, traditions such as gift-giving and merrymaking, cultural figures such as Santa Claus, or other topics. Many songs simply have a winter or seasonal theme, or have been adopted into the canon for other reasons.
Traditional Christmas carols include pieces such as "Silent Night", "O Holy Night", "Down in Yon Forest", "O Come, All Ye Faithful" and "Hark! The Herald Angels Sing". While most Christmas songs before the 20th century were of a traditional religious character and reflected the Nativity story of Christmas, the Great Depression brought a stream of widely popular songs of U.S. origin that did not explicitly mention the Christian nature of the holiday, but rather the more cultural themes and customs associated with it. These included songs aimed at children such as "Santa Claus Is Comin' to Town" and "Rudolph the Red-Nosed Reindeer", as well as sentimental ballad-type songs performed by famous crooners of the era, such as "Have Yourself a Merry Little Christmas", "Blue Christmas" and "White Christmas", the latter of which remained the best-selling single of all time as of 2024. Elvis' Christmas Album (1957) by Elvis Presley is the best-selling Christmas album of all time, having sold more than 20 million copies worldwide.
