Many stories are told via emojis, but Twitter and London’s Royal Opera Houseare taking it to the next level on Monday, July 17, in honor of World Emoji Day, using them to tell the story of an entire opera.

This isn’t the first collaboration between these unlikely partners: They first joined forces to tweet an opera in August 2009.

On Monday, the Royal Opera House will be tweeting all day long using emojis—and only emojis—to share the story of famous operas and ballets. There will be a new tweet every 30 minutes.
