Misc. Comments

  • This fugue was previously thought to have been arranged from a work by Johann Christoph Erselius. More recent analysis by Karl Heller ascertained that: "The B-flat major fugue, BWV 955, has hitherto been considered an arrangement by Bach of a G-major fugue by Johann Christopher Erselius (ca.1703-72), a hypothesis now disproven by source and textual studies. The G-major version is actually a transposition of an early version (BWV 955a) of the B-flat major fugue; both date from Bach's early years as a composer" — 'Die Klavierfuge BWV 955: Zur Frage ihres Autors und ihrer verschiedenen Fassungen', Das Fruhwerk Johann Sebastian Bachs: Kolloquium veranstaltet vom Institut fur Musikwissenschaft der Universitat Rostock, 11.-13. September 1990 (Koln: Studio, 1995) p.130–141.
    • Both BWV 955a, 955 discussed (as works in volume 3 of Schulenberg's 2013 "The Keyboard Music of J.S. Bach" - brief BWV955 analysis and discussion. (Schulenberg notes that it is not, pace!! Heller's statement, regarded as a matter quite disproven, but Schulenberg has no problem with 955 being accepted as part of the Bach canon - on the one hand "it will appear in the N[eue]B[ach]A[usgabe] reserved for doubtful clavier works", on the other, "less well documented works have been accepted into the Bach canon".
