For the first time, Kellner's 1726 manuscript (Source B) is used as the primary source for an edition of the ever-enduring Bach cello suites. Kellner's manuscript predates Anna Magdalena Bach's by 1-5 years. This is an important source, which all scholars consult in their preparation of the Suites. The slurring and ornamentation are based on the Westphal manuscript (Source C) because it presents the most meticulous care for copying slurs and articulation. The present edition includes suggested bowings and an alternate version of the 5th Suite based on J.S. Bach's own Lute Suite manuscript. Both versions of the 5th Suite are presented at with scordatura. Page turns were avoided wherever possible.
