First, listen to this opening:
Then, listen to this one:
That first clip is the Introitus from Mozart’s Requiem, composed in 1791. And the second is Handel’s “The Ways of Zion Do Mourn.” From 1737. Hear anything you recognize? There are a few connecting notes that appear in the first and not the second, and a bit of a tempo difference, as well. But they’re remarkably similar, no? (OK, fine. My title’s pure, unadulterated click-bait. I have guilt. Not enough to make me change it, of course, but I’m not made of stone. Honestly. There could be tears.)
In all seriousness, I don’t consider it thieving. Not really. I consider it “homaging” at worst. And I’m very much inclined to say that Mozart takes Handel’s theme and makes it his own in an extraordinarily effective and respectful way. By the time we hit the two-minute mark in the Introitus and the solo kicks in, we’re unmistakably planted in Mozartian territory. So what if he used a bit-O-Handel as a launching pad?
I did not come up with this comparison myself. Even though I have (subsequently) discovered it to be a fairly well-documented example of musical homaging/borrowing, I doubt I’d have recognized it unaided; I’m just not that familiar with the original funeral anthem. In fact, this might well have been the first time I’ve ever listened to HWV 264 in its entirety. I am grateful to Dr. Lorenzo Candelaria for pointing out the similarity during a lecture on the importance of analyzing Mozart’s Requiem as a liturgical work rather than as a concert-hall piece. Which is a whole ‘nother wonderful world of musical investigation.
