Why do so many Christmas songs have the chord D7 in them? What is it about that chord that is so "Christmas-like?" I am thinking of "Joy to the World," Jingle Bells," "Rocking around the Christmas Tree," "Holly Jolly Christmas," and others. These songs are typically in key of G and use a lot of D7 too, at least in my little Christmas Song book for Guitar. Whatever it is, it works. I mean, there's something about the D7 chord that makes me think of mistletoe and holly. Can any of you theorists explain this?
