Bach sources rediscovered in Weimar
A Bach source from 1772 that had been lost for fifty years has been rediscovered in the Thuringian State Music Archive in Weimar: The Herthum'sche Choralbuch contains the oldest source for Johann Sebastian Bach's four-part organ piece "Auf meinen lieben Gott".
The chorale book was last shown at an exhibition at the Bach Festival in Weimar in 1964 and had been considered lost ever since. Herthum's chorale book contains works for keyboard instruments from the 18th century for cantorial use, including pieces by Georg Philipp Telemann.
During cataloging work at the Thuringian State Music Archive, a complete copy of the score of Bach's Christmas Oratorio was also discovered at the Weimar Academy of Music, which may be a manuscript previously only mentioned in old sales catalogs and which could come from the estate of the well-known Bach scholar Franz Hauser (1794-1870).
