The accident occurred during a change of scenery for “Sadko”, a 19th century opera composed by Russian Nikolai Rimsky-Korsakov.
“The performance was immediately stopped and the public was asked to leave the stage,” Bolshoi told the Interfax news agency.
The Moscow Investigative Committee said in a statement it was investigating the death of the unnamed artist. According to the same source, the seriously injured dancer died before the ambulance arrived.
According to Interfax, the 37-year-old actress was crushed by a ramp that fell from the ceiling during a change of scenery.
This tragedy is not the first to hit the prestigious Moscow stage: in 2013, a violinist died after falling into the orchestra pit.
