"Bach made his arrangement of the fifth cello suite (BWV 1011/995) with apparent haste.. There is a suggestion that the dedicatee, M. Schouster, identified recently as a book-dealer in Leipzig, may have encouraged Bach to create a saleable version of a piece which he had written about ten years earlier. The first page is neat and properly spaced, with carefully formed note-heads and stems. Looking at the end of the tres viste section of the Prelude and the Bourée, the writing is more typical of a rough copy. He wrote note-names to clarify messy bass notes. Compared to the finished copy of Anna Magdalena’s BWV 1011, BWV 995 seems like a sketch.
If he were serious about writing with the lute in mind and preparing it for subsequent adjustment or intabulation, we would expect his handwriting to reflect it. Just because he has written “pour la Luth” at the top of the page, we need not conclude that he has done it with any conviction. If Bach set out to write real lute music, and not keyboard music with annotation, he might have done better than BWV 995. This version may have been the beginning of that process. As it stands, BWV 995 is a stab at arranging an earlier work for the lute, but it is not lute music."
