Friedrich Wilhelm Zachow, Herr Gott dich loben alle wir (LV 31)
Zachow’s prelude to “Herr Gott, dich loben alle wir” seems at the start a fugue on the first phrase on the chorale melody, but that turns out to be the somewhat elongated introduction. The complete choral melody is played the soprano voice with the other two voices as accompaniment in shorter notes. Noteworthy of this composition is that Zachow stays firmly in F major. Only two alterations spicen the music a little, for the rest Zachow uses the colours the harmonies within one tonality provide to drive the music forward (and the choral melody itself of course).
