- Trio Sonata No. 4, BWV 528
[10:0] (A=465)
The invocatory Adagio is unique among the 6 Trio Sonatas, making the movements 4 in number. It quickly gives way to a bright Vivace,
with two main themes. The first theme of the Andante is based on melodic intervals of a fourth; the second theme includes progressive intervals
of 2nd, 3rd, 4th, 5th and sometimes 6th; the two themes are combined at the end of this movement. The sassy Un poco Allegro theme also begins
with a fourth. Registration (Right Hand always on Hauptwerk, Left Hand always on Oberwerk): Adagio - RH Rohrflöte 8'; LH Quintadena 8'; PD
