“The Silence before Bach” is an approach to music and the trades and subjects that surround it through Bach’s works. A look at the profound dramaturgic relationship between image and music where the latter is not merely conceived as subsidiary to the image but as a subject of the narration in its own right. The film springs from a previously defined musical structure.The soundtrack feeds on works by J.S Bach and two of Felix Mendelssohn’s sonatas to create an architectural vault beneath which the story of the film unfolds ; a promenade through the XVIIIth, XIXth and XXIth centuries led by the hand of J.S. Bach.
