Kelli O’Hara’s Ties to Opera, From ‘The Gilded Age’ to the Met Stage

On the HBO costume drama “The Gilded Age,” Kelli O’Hara plays a New York grande dame forced to choose sides in an opera war: remain at the old guard’s Academy of Music, or defect to the Metropolitan Opera being built by the nouveau riche they had excluded.

When her character, Aurora Fane, joins a throng of socialites surveying the nearly completed Met, the camera lingers on her face, upraised in awe.

O’Hara herself is far more familiar with the Met, at least in its current incarnation. In addition to being a Tony-winning star of Broadway musicals and an Emmy nominee, she has been singing at the Met for nearly a decade, and is back now for a revival of “The Hours,” starring opposite Renée Fleming and Joyce DiDonato, opera legends both.

Still, the Met’s grand auditorium, which holds 4,000 people, inspires the same wonder in O’Hara as it does in Aurora. Although Aurora never had to fill it. And O’Hara does.

“Once I give over to it and believe in myself, I remember that this is the way my voice wants to sing,” she said.

This was on a recent morning during a break from rehearsals. O’Hara, 48, had traded her costume corset for a black jumpsuit. One hand held a paper cup of coffee. (A socialite would never.) Later she would return to the basement space where she is rehearsing “The Hours,” Kevin Puts’s adaptation of Michael Cunningham’s time-skipping novel, itself inspired by Virginia Woolf’s “Mrs. Dalloway,” which opens May 5.
