Building a new organ is always an exciting journey for an organ builder. What should a new organ look like, how should it sound, how should it fit into the church interior, what traditional reference points are there, what should be played on this new organ in addition to the important church music, how historical, how modern may the action, wind system and finally the entire pipework be built. In the Church of the Four Evangelists in the Protestant parish of Berlin-Pankow, the requirements were clear. An organ by the famous Berlin organ builder Carl August Buchholz (1796 - 1884) no longer existed in the church. Is it possible to rebuild a Buchholz organ in such a way that it seems possible that C.A. Buchholz would have built this new organ in exactly the same way in 1840, for example? We organ builders at the Wegscheider organ workshop set ourselves this special task, having already restored and reconstructed several Buchholz organs, visited and examined other surviving Buchholz organs and were very familiar with this particular organ sound language of the first half of the 19th century in the Prussian lands. A suitable specification with 27 stops was created, an early Schwellwerk with side doors (entirely in the Buchholz style) was designed, the metal and wooden pipes as well as the reed stops were built according to the models and the voicing was adapted to the church interior in terms of response, sound volume and dynamics. Particular emphasis was placed on the feel of the keys, which must harmonise with what the player hears. The aim was not to build a particularly light action, but rather one that harmonised with the early romantic sound. The historical keyboard aesthetics with the stop action, the music desk, the swell lever, the historical proportions between the manual pianos and the pedal keyboard also serve to immerse the performer completely in the early romantic tonal spirit.
