Oh, sorry. That'd be the Leonard Cohen song of that name ("Now, I heard there was a secret chord / That David played, and it pleased the Lord / But you don't really care for music, do you? / Well, it goes like this / The fourth, the fifth / The minor fall, the major lift / The baffled king composing hallelujah").

Famously covered by Jeff Buckley, Rufus Wainwright on the Shrek soundtrack (I don't understand how it has anything to do with that film, but oh well), and by k.d. lang on her new CD. And also, it turns out, by a bunch of other people. ;)
