Sphere of influence In the course of his life, Wagner built over 50 individually designed organs, both for large churches and for smaller village churches, of which 15 have been preserved in larger parts, as well as eight cases or smaller remnants. From his workshop in Berlin, his sphere of activity extended mainly to the northern German Prussian
Hohenzollern states, in addition to the residential cities of Berlin (8 organs) and
Potsdam (4) and
Brandenburg an der Havel (3) to the entire Margraviate of Brandenburg including
Altmark (
Werben (Elbe),
Salzwedel),
Uckermark (
Angermünde,
Gramzow,
Schwedt/Oder) and
Neumark (
Königsberg), in
Pomerania (
Stargard,
Wartin) and the
Duchy of Magdeburg. But also in
Kursachsen (
Jüterbog) and Norway (
Nidaros Cathedral in
Trondheim) he built organs. Today, 15 organs with the largest original components have been preserved, the most valuable in the
St. Peter and Paul Cathedral Brandenburg, as well as 8 cases or smaller remains.
Characteristics Wagner built instruments that combined and further developed Central German and North German elements of organ building. However, the work principle cultivated in the baroque period of northern Germany was abandoned in favour of sound fusion and a single overall case. The sound characteristics include the powerful
intonation, the well-staffed
pedal keyboard (without pedal coupler), mixtures and the manual transmissions built into some instruments. In the course of his life he built over fifty individually designed organs, both for large churches and for small village churches, no two of which were completely alike. His
casings were rich in variation, often bearing sculptural decoration and occasionally moving timpani and trumpet angels in the Silesian tradition, inspired by
Johann Michael Röder. All of these instruments are extremely valuable testimonies to a highly developed musical culture, which were also used by the musical greats of their time. On 8 May 1747, for example,
Johann Sebastian Bach played the relatively small Wagner organ at Potsdam's
Heilig-Geist-Kirche. The organ works of his son
Carl Philipp Emanuel Bach were written in the context of the organ built in 1755 by Ernst Marx and Peter Migendt. of the princess
Anna Amalia, which is now located in
Karlshorst.
Today's holdings Fires, lack of maintenance as well as alterations resulting from the musical zeitgeist of the 19th century and the consequences of the Second World War have left only 15 more or less originally preserved instruments and eight other instrument remnants, mainly cases (some still with original stock). The Potsdam firm
Alexander Schuke Potsdam Orgelbau has rendered great service to the restoration of Wagner organs in the course of its existence. On 26 August 2006, the Joachim Wagner Society was founded in
Rühstädt with the aim of researching and maintaining his unique heritage. == List of works ==
