Prelude in C Minor, BWV 999

Sourced context

The Prelude in C Minor, BWV 999, is, according to its only extant 18th-century manuscript, a composition for lute by Johann Sebastian Bach. In the manuscript, conserved as Fascicle 19 of Mus.ms. Bach P 804 at the Berlin State Library, Johann Peter Kellner wrote the piece down in keyboard notation. The time of origin of the work is not known: possibly Bach composed it in his Köthen period, that is, between 1717 and 1723, or the early years of his ensuing Leipzig period. Kellner's copy was produced after 1727, but before Bach's death in 1750.
