The chorale “Sei Lob und Ehr’ dem höchsten Gut” was written in 1673 by Johann Jakob Schütz. It was sung on the melody of “Es ist das Heil uns kommen her”. Bach wrote his cantate and chorale prelude using this melody and so does Kittel.
This first prelude by Kittel has the chorale melody in long notes in the soprano voice, accompanied in equally long notes in the alto and tenor voice. The rythmic variation is provided by the bass voice, played with the pedals.
