Christe, der du bist Tag und Licht, BWV 1096

Many early organ works of Bach are in the Neumeister Sammlung/Collection, besides compositions by other composers like Sorge, Zachau and Johann Michael Bach. They are all chorale preludes, like this one on the hymn 'Christe, der du bist Tag und Licht' or 'Wir danken dir, Herr Jesu Christ', BWV 1096.
Important note: there are some small differences with the score showed in the video and the score I played from (especially the last bars).
