Johann Christoph Oley, Wo Gott der Herr nicht bei uns hällt
Oley’s prelude to the chorale “Wo Gott der Herr nicht bei uns hält” is a short manualiter piece in f minor. Oley has the melody cleverly hidden in plain sight. With a changed rythm and some added notes, you have to listen closely to recognize the choral melody.
The recording was done with the Hauptwerk software and the sample set of the Holzey organ of St. Peter and Paul in Weissenau by Prospectum (https://www.prospectum.com/index.php?language=english&id1=2&id2=9).
