BWV 101 - Provenance:
The autograph score:
In all likelihood this became part of the inherited portion of cantata scores that went to W.F. Bach soon after his father’s death. It must have been lost during W.F.’s lifetime and has never appeared elsewhere thereafter. The NBA I/19 KB records a dozen copies of the score that were made in the latter half of the 18th and also during the 19th century. Three of these manuscript copies used the original score to copy from. One copy is by Christian Friedrich Penzel, another by Johann Friedrich Agricola and one consisting only of the 1st mvt. is by W.F. Bach. All the others are either copies of these copies or had access to the original set of parts.
The original set of parts:
There are 18 parts which were copied by Johann Andreas Kuhnau and two anonymous copiers simply known as Copier 1 & 2. Bach himself wrote out the substitute/doublet part of the Flauto traverse and made corrections and additions in the other parts. Missing are the Violino I and II parts as well as an untransposed continuo part. The Violino parts I and II that do exist are doublets. The NBA KB states that “it is usual for doublets of the Violino I and II parts to exist. [This means that at least two violin players could be playing from each part as we often see happening in symphony orchestras today: the concert master and the violinist next to him/her share a single part, although it would be easy to make additional copies of the part available.]
This original set of parts were, as usual, in the library of the Thomaner School, where Anna Magdalena had given them for safe keeping. The Bach-Archiv has jurisdiction over the set, but they are temporarily in the Leipzig City Archive.
Date of 1st performance:
August 13, 1724 (Dürr)
Later performances:
It can be assumed that Bach performed this cantata more than once, but there is no hard evidence to verify this claim, but some intriguing possibilities are present: for a later performance Bach had dropped the colla parte wind instruments; changed the Flauto traverse solo in mvt. 2 [this is notably the most difficult of all obbligato flute parts in all of the cantatas according to professional musicians who have tried to play it.] Bach either changed this part to a violin obbligato in 1724 or at the time of a later repeat performance because he did not have a flute player who could play it properly; had the flute player in mvt. 6 play a revised version of the part at the later performance; had the chorale melody in Mvt. 7 played by both the flute and the oboe in unison an octave higher, but dropped this at the later performance to have only the flute play at regular notation. |
