Crackling slightly down a transatlantic phone line, Audrey Luna has a pleasant, normal speaking voice. But she's only able to use it for 10 minutes.
Come Friday evening, these same vocal cords will unleash a note so dizzyingly high, so astoundingly rare, that archivists say New York's Metropolitan Opera has never heard it in 140 years - at least, not since her last performance.
And like a world-class athlete on game day, she needs to conserve her strength.
Ms Luna is a coloratura soprano - the voice type capable of the highest notes - and specialises in thrilling, trilling vocal runs that pour out strongly even at their peaks.
Few people alive have the potential to reach the note now winning her headlines - the A above high C.
To put that in context, Christmas choristers singing the descant line of Hark! The Herald Angels Sing will usually hit a high A - some with difficulty. Ms Luna's note is a full octave - or eight notes - higher than that.
The opera showcasing this rarity is Thomas Adès's The Exterminating Angel, a savage, surrealist piece based on the 1962 Luis Buñuel film of the same name.
Ms Luna plays Leticia, an opera diva who joins a well-off couple for a glittering dinner party. Macabre twists unfold as the partygoers find they have entered a strange vortex - and are trapped in the house when the evening ends.
It's a supernatural note for a supernatural story - and the Oregon native is hitting it twice a night.
