From the Notebook of Anna Magdelana Bach. (I think attributed to Boehm, I didn't research as well as I should).
The next submission in my study of this work, I recorded this on the challenging organ model of the Bamboo organ of Roeselare. Due to the long resonance of the room and the somewhat eccentric voicing and releases of the pipes, I broke up some of the legato sections with phrasing. This was done under my own descretion, not under the tutelage of a teacher steeped in Baroque lore, so if it is atypical, please forgive me :-)
I uploaded this a second time on a different organ with the phrasing played as marked. Let me know which you prefer, or if you have any suggestions.
