The song also includes what I consider the most Christmassy chord of all—a minor subdominant, or “iv,” chord with an added 6, under the words “underneath the Christmas tree,” among other places. (You might also analyze it as a half-diminished “ii” 7th chord, but either interpretation seems accurate.) The same chord is found, in a different key and inversion, in Irving Berlin’s “White Christmas”—on the line “children listen to hear sleigh bells in the snow,” specifically under the word listen, among other spots.While many people don't know what a "iv chord" means, he does link it up sonically with an aural cue most people can recognize.
