In Neumeister's manuscript the prelude to "Heut triumphiret Gottes Sohn" follows immediately after the prelude to "Wie schön leuchtet der Morgenstern" by Friedrich Wilhelm Zachow. Although Neumeister does not write a composer's name above the piece, it is sometimes attributed to Zachow. Fact is that texture and feel it is not unlike Zachow's prelude to "Wie schön leuchtet der Morgenstern" so the attribution to Zachow is not unlikely. Neumeister omits some notes and many notes that are there are highly unlikely. I tried to correct them as best as I could. All editorial decisions are marked in the score. I've never had to use so many footnotes in just 59 bars of music.
