In 1968 he received his doctorate with a dissertation "Untersuchungen zur Kompositionstechnik der Motette im 13.
159 (now assumed to be by Bach, but formerly regarded as spurious) and Jauchzet dem Herrn, alle Welt, BWV Anh.
He divided his book in two parts, one dedicated to the facts and history of the works, the other to musical analysis.
