The chorale prelude on 'Durch Adams Fall ist ganz verderbt', BWV 705 is part of the so called Kirnberger Chorales. A collection of Bach pieces that Johann Kirnberger collected, hence the name.
The year of composition is probably around 1708. Bach served as organist in Arnstadt from 1703 till 1707. This chorale prelude appears as an organ motet in the 'stile antico', it has been suggested that it is an arrangement of a vocal movement. It is harmonised in four parts. Each choral phrase is treated in turn, with each phrase beginning with a fugal entry.
Sonus Paradisi sampled the Wender 'Bach' organ (1703) of Arnstadt for Hauptwerk. So it's always nice to play Bach's early organ/keyboard works on this organ/sample set.
