Stock Photo - 20 September 2021, Brandenburg, Werder (Havel): Organ builders Johannes (l) and Michael Schuke, managing directors of Alexander Schuke Orgelbau GmbH, check the quality of a plate made of a molten tin-lead alloy drawn onto sandstone. The plate is then processed on a planing machine, brought to the correct material thickness and rounded out to form organ pipes. In the foreground are two ingots as they are delivered as raw material for the production. On 25.09.2021, between 10.00 and 15.00, an open day will be held in the traditional workshop. Visitors can experience the construction and of course the sound of an organ. The organ was chosen as the instrument of the year in 2021.
