In a video posted by the Joyous Music School, four children under the age of 8 perform "Firework" by Katy Perry.
The group, based in Long Island, New York, goes by the name the Joyous String Quartet, and the children have been playing together since they were 4 years old.
Ellen DeGeneres featured lead cellist Justin Jun Yu on her TV talk show last year.

The video, posted March 1, had more than 100,000 views at the time of publication.
