If you’re a singer, watching this video might give you the creepy-crawlies. It’s Dame Kiri Te Kanewa singing “Dove sono i bei momenti” from Le nozze di Figaro at the Metropolitan Opera’s Centennial Gala, 1983. Kiri sings this staple aria of hers as beautifully as you would expect.

Near the end, a terrifying thing happens: a memory slip. It’s super subtle, tricky to catch right away (that probably means it’s an easy trap for sopranos).

This one is all about the recovery though; smooth like butter, even at the Met with thousands of (real) opera folks watching. Have a watch, and skip to 5:00 if you’re impatient. Oh, and stay tuned for her beautiful exchange with Maestro Levine as the applause roars in.
