The song begins with a "sparking" bit of percussion "that resembles an antique music box or a whimsical snow globe." After Carey's a cappella style vocal introduction, the song introduces other seasonal percussive signifiers including; celebratory church-like bells, cheerful sleigh bells, and "an underlying rhythmic beat that sounds like the loping pace of a horse or reindeer. These sounds echo religious and secular musical touchstones, without veering blatantly too much in either direction, and give the song an upbeat, joyous tone."
