(ALKU 91, 2010)

Side A (Kippschwingung)

  • Fuga a 3 Soggetti (Contrapunctus XIV)
  • Contrapunctus VII
  • Contrapunctus IX
  • Contrapunctus III
  • Contrapunctus XII

Side AA (Rechteckschwingung)

  • Contrapunctus V (slow)
  • Contrapunctus XI
  • Contrapunctus VI
  • Contrapunctus V (fast)
  • Canon per Augmentationem in Contrario Motu
  • Contrapunctus VII

Track A1, actually the very last of the fugues in Bach's score, was left unfinished due to the composer's untimely death, so the abrupt ending in this rendering is perfectly normal. The fugue includes the famous BACH motif (the notes B-A-C-H as in German nomenclature, in which B is B flat and H is B natural).

Final page of 'Contrapunctus XIV', the unfinished piece

Bach’s use of 'open score' notation in his manuscript of Art of Fugue - meaning that each fugal voice was written on a separate staff - seemed to leave the question of instrumentation 'open' as well. Was it meant for the keyboard, or could it be played by any instrument or ensemble? (…) Bach enthusiasts debate which keyboard instrument is best suited to Art of Fugue1.
