Watch the Met Opera's Emotional Tribute to Paris' Terror Victims

In an emotional display of solidarity with the victims of the Paris terror attacks, New York's Metropolitan Opera began its Saturday matinee performance of Puccini's Tosca a little differently than usual.

Led by conductor Plácido Domingo, the chorus and orchestra opened the show with a powerful rendition of "La Marseillaise," France's national anthem, the New York Times reports. 

A special insert was placed in audience members' programs, the Times also notes, reading, "The Metropolitan Opera mourns the victims of the Paris terrorist attacks and will perform the French National Anthem as a show of our solidarity with the citizens of France at today's matinee performance."

One audience member, singer Erik E. Larson, recorded the performance and shared the video on Twitter. It has since been retweeted more than 3,000 times.

In a tweet thanking Larson for the video, the Met Opera choristers described the way they felt during the performance.

"It was very moving to be part of that solidarity, shared by everyone in the opera house," they wrote.
