It is always worth paying special attention to the music of Ingmar Bergman's films, because it always carries great significance. This is one of his almost numerous films dealing directly with music, as it tells the story of a brilliant young pianist who in an accident loses his sight but goes on playing, although he can't get any stable position, and as an alternative he educates himself to a piano tuner. The scenes from the school for the blind are the most poignant and interesting in the film, especially the class of blind children reading together, while the scene then changes into the concert the blind pianist is giving for the blind. His films with music for a major theme are perhaps his most personal and interesting and might be the best ones, and here for the first time he pierces the mental darkness of the black side of music and creation. Mai Zetterling is the enduring light in this darkness, and when you lose her in the beginning you long for her to reappear, which of course you are certain she will, and she does indeed. Birger Malmsten as the blind pianist makes a very delicate performance of both great pain and superior integrity, and all the other actors are outstanding as well, especially Douglas Håge as the rowdy restaurant boss. As a film of his youth, it is still of the experimental stage of Bergman's long career, but as such it is perhaps the most interesting of his early experimenting films.
