In the handwritten copie by J.Kellner from 1720 J.S.Bachs BWV 999 is called "Prelude in c moll pur la Lute". Since, as with other Bach lute works, it is still discussed whether Bach composed this prelude for the "Lautenclavier" or "Lautenwerck" that was develloped in Bachs time or for the lute, both historical and modern plucked instruments as well as historical and modern keyboard instruments are used.
