The penultimate volume of our edition featuring organ works of the Northern German Baroque focuses on the complete organ works of Jakob Praetorius the Younger and Paul Siefert. Hieronymus Praetorius, the organist at the Church of St. James in Hamburg, is regarded as the most important founding figure in the field of independent Northern German organ artistry. Three of his four songs, Jakob, Johann, and MIchael who already in 1604 had contributed a quarter of the eighty-four cantional settings to the renowned Hamburger Melodeyen Gesangbuch, is said to have developed a special form of fingering and pedal technique making it possible for the organist to assume a very relaxed sitting position and corresponding to his serious, sober, personal disposition. According to the music critic Johann Mattheson, Praetorius's works were "mroe serious" and "more forcefully elaborated" than those of his friend Scheidemann.
