Partita "Herr Jesu Christ wahr Mensch und Gott"

Oh well, so the plot thickens. So it seems that Mus. Ms.30439 is dated to about 1700, as Auke Jongbloed has now found out. I'm not surprised he overlooked this because the way the Staatsbibliothek presents its digital manuscripts not only gives you no information about date and provenance on the relevant pages themselves, but I don't even know where to look for this information -- I have tried repeatedly and I just cannot find it, and I have a mind to tell them this needs amending. Anyway, the date corroborates the attribution to Johann Heinrich Bödecker. I use the ö because that seems to be the more official spelling, at least our man seems to have been hired as Mr. Bödecker according to the records in the archives of the Berlin court -- but Bodecker occurs likewise, for example in our manuscript. But not only there. I have tried to find at least one other occurrence of the name "H. Bodecker", such as it appears in the ms., and to find proof that this was the same person as Johann Heinrich Bödecker. I did -- the evidence is not 100% conclusive, but almost. The details are in the video description. In the video itself I have added the words of the hymn, in German and English. It has 12 stanzas and fits the score exactly if you repeat the initial chorale setting at the end -- and I'm practically certain you are meant to (Auke did it too in his original recording). The Anloo organ also proved an astonishing fit for this marvellous piece. I originally thought of it because it was built by Johann Radeker (together with Rudolf Garrels), and Johann Radeker was the father of Henrik Radeker, to whom Auke originally attributed the piece. As it turns out, Bödecker had a very similar instrument in Berlin cathedral -- quite an ancient one, dating from 1557; interestingly, it has been noted that the Anloo organ is quite archaic in its tonal design. Anyway, judge for yourself -- to my ears the piece sounds as if it had been written for this organ.
