Polanski’s The Pianist (2002) displays a particular approach of music. The artistic commitment, which is the main subject of the movie, allows the director to question how an individual can face Evil. The way the music is used in this movie in not an unexplored topic of research. However, no study has so far sought to thoroughly show how an analysis of The Pianist can shed new light on Polanski’s reflection about the status and function of music, which plays an essential role in the director’s filmography. Thus, the main aim of our article will be to question in which way and to what extent music appears to the lead character as a means of survival and resistance against the Nazi’s dehumanization process. We will also show that Polanski’s vision of music, far from being naive or excessively idealistic, proves to be fundamentally ambivalent.
