Siciliano from "Flute Sonata in E-flat Major" BWV 1031 (J.S. Bach)

A beautiful melancholic piece originally composed for flute and harpsichord. This arrangement for solo guitar is by japanese guitarist Kohei Minami. I got introduced to the music long time ago when I watched the movie "Fanny and Alexander". There's a scene in the film that got stucked in my mind where the Lutheran husband plays this movement on flute in what looked to be a very cold, dulled and unornamented room.
