Resümees der Beiträge 189 Furthermore, Bach’s arrangements and partially new compositions based on movements from Reinken’s collection of sonatas „Hortus musicus“ (1689) date from an earlier period than hitherto reported. This results in a new view of the young Bach’s compositional development, especially before 1710. Friedhelm Krummacher: Bach and the North German Organ Toccata: Ques- tions and Reflections This is an attempt to trace development by which the multi-part North Ger man organ toccata with its frequent changes of free and strict stylistic compo- nents resulted in the two-part formal pair - Prelude (Toccata, Fantasia, etc.) and Fugue. A manifest and relatively rapid assimilation of the tradition was followed by Bach’s remodeling, especially with regard to the relationship bet- ween improvisatory style and thematic control, and his eventual departure from the North German prototype. Hans Grüss: The Tradition of the Cantus Firmus Canon. A Supplement to the Topic „Bach and the Middle Ages“ The compositional procedure of a cantus firmus movement and of a cantus firmus canon forms one of the important Connections that binds Bach’s work with thirteenth-century music. It is a question of an uninterrupted tradi tion, yet with repeatedly broken transmissions. Strangely enough, in a lecture on the subject in 1950, Heinrich Besseler did not take this connection into consideration. Winfried Schrammek: Johann Sebastian Bach’s Position Concerning 32-foot Or gan Pedal Stops. An investigation of organ building initiated or tested by Bach reveals that he desired „the greatest gravity“ from the organ of his time. As an important prerequisite for attaining this goal he desired an organ pedal with a 32-foot stop. Französische Resümees Martin Petzoldt: « Ut probus et doctus reddar »: concernant le röle joue par la theologie dans l’education scolaire de Johann Sebastian Bach ä Eisenach, ä Ohrdruf, et ä Lüneburg. La consideration de ce theme complexe necessite un rassemblement de multi ples details relatifs aux histoires personnelies, au Systeme d’enseignement et ä la litterature scolaire, et aussi aux interpretations theologiques qui charac- terisaient de differentes universites. Gräce ä la survivance de certains docu- ments, nous pouvons reconstituer le Systeme d’education scolaire ä Lüneburg; quant aux cas d’Eisenach et d’Ohrdruf, nous avons recours aux plans de reforme d’Andreas Reyhers, et ä des materiaux relatifs ä la vie de differentes per- sonnes. Parmi les buts de l’education dans ces villes il faut reconnaitre la piete, l’erudition, et l’aptitude.
