But tonight, singers at the prestigious performance venue will take center stage and belt lyrical tweets from the world's first Twitter opera.
The lines of the libretto, written using a maximum of 140 characters, are being entirely composed by Twitter users @YourOpera, and will be set to music by composer Helen Porter. (All of the lines can be viewed on the Royal Opera House's blog.)
Alison Duthie, a spokeswoman for the Royal Opera House, hopes the micro-blogging experiment will encourage people to learn more about opera.
"It's the people's opera, and the perfect way for everyone to become involved with the inventiveness of opera as the ultimate form of storytelling," she says.
