Trio Sonata No. 4, BWV 528 Click to Listen [9:2]
The invocatory Adagio (R.H. HW Rohrflöte 8' + Gamba 8' + Gamba Celeste 8'; L.H. Positiv Bourdon 8' + Rohrflöte Celeste + Holztraverse 4' + Nazard 2 2/3; PD Subbas 16' + Gedactbas 8') is unique among the 6 Trio Sonatas, making the movements 4 in number. It quickly gives way to a bright Vivace, (R.H. HW Principal 8' + Octave 4' + Superoctave 2'; L.H. Positiv Bourdon 8' + Holztraverse 4' +Octave 2' + Sifflöte 1 1/3; PD Subbas 16' + Octave 8' + Gedactbas 8') with two main themes. The first theme of the Andante (R.H. HW Principal 8' + Rohrflöte 8' ; L.H. Positiv Bourdon 8' + Gambe 8' + Holztraverse 4' ; PD Subbas 16' + Gedactbas 8') 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 Principal 8' + Octave 4' + Superoctave 2' + Mixture 1 1/3'; L.H. Positiv Bourdon 8' + Gambe 8' Holztraverse 4' + Nazard 2 2/3' + Octave 2' + Sifflöte 1 1/3 + Octava 1'; PD Subbas 16' + Octave 8' + Gedactbas 8' + Octave 4') also begins with a fourth. No reverberation has been added to this virtual performance and the organ is "unenclosed" throughout. Instrument: Mühleisen Orgelbau, St. Cornelius and Cyprian (1997) - Samples by Gernot Wurst
