Mark Steinbach, University Organist and Senior Lecturer in Music, performed a recital July 29 on north German organ builder Christoph Treutmann's magnum opus in Grauhof monastery near Goslar. The organ, built in 1734, consists of 42 stops on three manuals and includes a 16 foot "string stop" as well as a full-length 32 foot length bass posaune (trombone) stop about which on of Treutmann's contemporaries said "it was not very dissimilar to the sound of a rumbling thunderstorm."
Steinbach went on to Angermünde to perform a recital on an organ built in 1740 by Joachim Wagner, a student of Treutmann. Johann Sebastian Bach himself played and admired the instruments of Wagner when he visited his son C.P.E. in Berlin and Potsdam, but those instruments were destroyed in WW II. This organ includes string stops as well, but also whimsical stops, such as spinning golden suns which activate small bells and timpani which can be played by the organist's feet which activates golden ornaments, or putti. The keyboard action is completely mechanical in both of these instruments.
