This is SO well done.
A human piano made up of opera singers has taken Quebec by storm at the city's Festival d'Opéra.
Members of the public were encourage to join in and test out the human piano by standing on the keys. Each key on the piano was represented by a different opera singer, each one assigned a specific note.
As the video shows, various people and even animals got involved, resulting in a bit of Bizet and some other musical surprises.
The project was put together by TFO, the French-language television network.
