Georg Böhm: Vater unser im Himmelreich, Leonard Schick, organ 

Here I decided to use a registration described by Johann Friedrich Doles in around 1769. Doles was a pupil of J.S. Bach. The particularity here is having a 16' and a 4' as solo registration in the right hand.
Another Bach pupil, Johann Friedrich Agricola, did recommend the registration 16' 4' for trios. He recommended a Quintadena 16' or Hohlflöte 16', which were typical manual stops, which shows also Agricola had it in mind for a manual in the trio.
