Middle-period Sources [i]: The Zellerfeld Tablatures

The 27 non- Heinrich Scheidemann pieces, while including many anonyma, provide further confirmation of the stature of Ze1 as a primary document of the Hamburg school, even apart from the Scheidemann pieces. A predecessor of Bruno Heinrich Jordan's at the Catharinenkirche, Anton Schuler, seems to have been a collector of organ music by Scheidemann as well. The last verse of Scheidemann's Erbarm dich mein o Herre GottWV 4 has been finished by a particularly elegant and experienced hand, whose identity is unknown; it is certainly neither Strunck's nor Scheidemann's. The watermark may or may not constitute an argument for the inception by Strunck of Ze1 but it certainly corroborates the Brunswick origin of the manuscript. Caspar Calvor went on to study at the University of Jena and from 1672 at the University of Helmstedt, before becoming pastor at the Salvatoriskirche in Zellerfeld, a small town in the middle of the Harz Mountains, in 1677.
