Musical talent does not always translate into great riches or fame. Told through the eyes of Johann Sebastian Bach's widow (Christiane Lang), this biopic recounts the life of the composer, a genius perennially in search of royal patrons and greater recognition. But the real focus of the film is the music; included are extracts from 25 Bach compositions such as the Brandenburg Concerto no. 5 and Sonata no. 2 in D Major for Viola and Harpsichord.
