Medium is a film portrait of pianist and artist Margarita Fernández. Instead of retelling the story of a life, Edgardo Cozarinsky combines scenes of Fernández playing entire piano pieces with her reflections on music and art, memories of a specific concert, archive footage of performances in the 70s and encounters with her students. Brahms is the other protagonist of the film alongside Fernández, as everything seems to revolve around him for her: when she’s at the piano, in her stories and reflections, in her attempts to articulate what it means to make music, in her thoughts on passion. Fernández has an engagingly calm, intelligent and sensitive way of engaging with the world and the filmmaker and is more than an individual artistic personality in this film: Cozarinsky places her in an in-between space, making her visible as a mediator who builds bridges between the past and the present, between different generations, between scores and music, sounds and images and her art and that of cinema.
