Samuel Scheidt’s eight-part motet 'Allein nach dir, Herr Jesu Christ' survives as an autograph in a composite manuscript in the Stadtbibliothek Braunschweig. However, the original nine part books (eight vocal parts and basso continuo) of this single known source survive incomplete; the first vocal part book is missing. Editor Stefan Steinemann has convincingly reconstructed the missing Prima Vox part, thereby making this work available in a printed edition for the first time.
