The Great Organ
The large organ at the west gallery is a new construction of world-renowned organ builder G. F. Steinmeyer & Co. (Oettingen, Bavaria) from 1962 and has five manuals, a pedalboard, 86 stops and 6,697 pipes. Its unique features include the Zimbelstern and the tubular bells installed in 2015.
Based on the organ type by Johann Gottfried Hildebrandt (1768), Steinmeyer developed a large organ which can be used for a broad repertoire of styles. As with the organs before it, the facade extends into the central axis, with stepped and flowing sections along the sides which envelop the centre like a gown and thus blend seamlessly with the light baroque room designed by Johann Leonhard Prey and Ernst Georg Sonnin.
The instrument was technically overhauled during the work carried out in 2009 and 2010. Much of the key action (the link between the keys and the individual pallets) was rebuilt. Components of aluminium and plastic were replaced with systems, primarily in hardwood, which have proven their worth over the centuries, making it easier to bridge the distances, some of which are extremely long.
The sound structure of this organ, the so-called ‘disposition’, was left largely untouched, as it is logical and offers an extremely large and now rare selection of principals, mixtures, flutes and reed stops. The quality of the pipes and the voicing (the fine-tuning of the individual pipes) also proved to be of high quality. With the wind supply stabilised and the voicing carefully tuned, something extraordinary was achieved today: the tonal voicing of 1962 remains completely intact, but now its beauty and subtle nuances can be enjoyed to the full for the first time. Despite its impressive size, the instrument radiates noble elegance and warmth.
In 2015, organ builder Johannes Klais (Bonn) installed a glockenspiel at the rear wall of the organ, which works with 25 tubular bells (chimes ranging from d0 to d2) and can be played electrically at the primary console.
