A nice, light and perhaps a little fragile composition by Johann Gottfried Walther on the Lutheran chorale "O Welt, ich muss dich lassen".
Johann Gottfried Walther (18 September 1684 – 23 March 1748) was a German music theorist, organist, composer, and lexicographer of the Baroque era.
As an organ composer, Walther became famous for his organ transcriptions of orchestral concertos by contemporary Italian and German masters. He made 14 transcriptions of concertos by Albinoni, Gentili, Taglietti, Giuseppe Torelli, Vivaldi and Telemann. These works were the models for Bach to write his famous transcriptions of concertos by Vivaldi and others.
On the other hand, Walther as a city organist of Weimar wrote exactly 132 organ preludes based on Lutheran chorale melodies. This one is a nice example.
Played on the Zwolle instrument.
Manuals: flutes 4' (all 4 of them to achieve a nice chorus)
Pedaal: Octaav 4' (for the c.f.)
