The message is that no kid is 'out of tune'
Everyone can sing!
That is a core belief of the "Filling the music" project, created in Switzerland, where youngsters from 5 to 18 are taught to perform covers of hit songs.
The resulting videos from the talented youth choir aren't just great for kids' self-confidence. They have also gone viral on YouTube!
The incredible success has seen tens of millions of views in the space of a few weeks.
