Trio Sonata No. 4, BWV 528 Click to Listen [9:35] (a=466 Hz)
The invocatory Adagio (R.H. Hoofdwerk Prestant 8' + Speelfluit 4'; L.H. Rugwerk Fluit does 8' + Holpijp 4'; Pedaal Bourdon 16' + Prestant 8') is unique among the 6 Trio Sonatas, making the movements four in number. It quickly gives way to a bright Vivace, (R.H. HW Prestant 8' + Speelfluit 4' + Quint 3' + Octaaf 2'; L.H. RW Fluit does 8' + Prestant 4' + Octaaf 2'; PD Bourdon 16' + Prestant 8' + Octaaf 4') with two main themes. The first theme of the Andante (R.H. HW Prestant 8' + Speelfluit 4' + Quint 3'; L.H. RW Fluit does 8' + Prestant 4' + Quint 1-1/3; PD Bourdon 16' + Prestant 8' + Octaaf 4') 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 theme of Un poco Allegro (R.H. HW Roerfluit 8' + Octaaf 4' + Mixtuur 4-6 st.; L.H. RW Fluit does 8' + Prestant 4' + Scherp 4 st.; PD Bourdon 16' + Prestant 8' + Octaaf 4' + Mixtuur 4-6 st.) also begins with a fourth. WellTemperament-FifthComma.
