The sheet music for Johann Strauss' The Blue Danube is constructed by moving musical symbols. A baton-toting conductor note tries to direct his fellow notes in performing this musical piece, but finds that one of the notes has become drunk.

What's the point of music? You might be tempted to answer that it's an enjoyable pastime or an art form, but nothing really essential. For the first time, a documentary shows the opposite.

In recent years, the discoveries of international neuroscience researchers have revolutionized our understanding of the impact of music on our brains. This film is a behavioral and neurological investigation whose ambition is to unveil the mystery of music's powers in our lives.
