10. “Eine Einladungsschrift zu musikalischen Vorlesungen Göttingen,” reads its subtitle: an invitation to lectures on music at Göttingen in 1777. A brief summary of its contents is given in Johann Nikolaus Forkel, Allgemeine Litteratur der Musik (Leipzig: Schwickert, 1792; reprint Hildesheim: Georg Olms, 1962), 419. The work was reprinted, evidently without permission, in Carl Friedrich Cramer, Magazin der Musik, I (1783; reprint Hildesheim: Georg Olms, 1971), 855–912.
