How can you send a message to the world? We all know how to send a text message or use a social app, but if we want to find more original and creative way? We can use music to express a thought and send a message to the world. This project is created by Primary School students and their teachers Monica Sandri & Serena Zanotti. We decided to publish this work to give students a tangible sign: studying and working in a creative way produce real fruits and give great satisfaction.
