Sonaten: The Sonatas and Partitas for solo violin by Johann Sebastian Bach are considered “the Himalayas of violinists". Yehudi Menuhin first recorded the complete works mid-1930s. The film, focuses on the Sonatas. It is a true dialogue between the recording of Yehudi Menuhin and Claire Bourdet, playing them today. The different movements are played in turn until they are merged into an unexpected polyphony. This is a film about music as an image of time.
