Leipzig time

Leipzig revision of the Weimar organ chorale "Wenn wir in höchsten Nöten sein" (few, mainly rhythmic changes); incompletely survives (up to m. 26a).

C. P. E. Bach added the chorale found in P 271, Fasz. 2, by Christoph Transchel (= Anon. Vr, identified by P. Wollny, BJ 2023) after BWV 769, with a few changes, to the first printing of the Art of the Fugue (BWV 1080.2) in 1751; according to its preface, the blessed man in his blindness "dictated this four-part movement to the pen of one of his friends from the Stegereif" (see Doc. III No. 645). Like the penultimate chorale arrangement BWV 667, BWV 668 also goes back substantially to the organ booklet.
