I was watching a DVD of an older Met production of Verdi’s Rigoletto earlier this week, one of their telecasts from the late 1970s. I haven’t listened to this opera much in general, and so when I got to Gilda’s aria “Gualtier Malde . . . caro nome chi il mio cor” about how she loves this guy who turns out to be the the Duke, I was sitting there racking my brains trying to figure out why it sounded so oddly familiar.
It took me a minute, but I figured it out.
