In March 2017 organist and harpsichordist Peter Kofler launched his ongoing Bach project: a complete recording of Johann Sebastian Bach’s organ works. Unlike performers of earlier complete recordings, Kofler opted for a “modern” instrument for this enterprise. For not only was J. S. Bach the perfecter of a great polyphonic era, he was an innovator and stimulator as well, particularly in the field of organ music. Be it the introduction of the tempered tuning system, the virtuoso use of the organ pedal or the development of the fortepiano: Bach significantly contributed to each of them and was one of the first to employ the possibilities of these modern developments. The four-manual Rieger organ at the Jesuit church of St. Michael’s in Munich with its 75 stops offers many of the characteristics verifiably valued by Bach. It features an imposing fortissimo and a multitude of characteristic stop timbres that the cantor of Leipzig’s Thomaskirche partly could only dream of in his days.
