Organ building

The profession requires specific knowledge of such matters as the scaling of organ pipes and also familiarity with the various materials used (including woods, metals, felt, and leather) and an understanding of statics, aerodynamics, mechanics and electronics.

The instrument is then usually partly or wholly assembled in the workshop, dismantled, and reassembled on-site, after which the pipes receive a final tuning and voicing.

A complete overhaul of an organ consists of disassembly of the pipes and thorough cleaning of all components and maintenance where needed; changes and additions may also be made to the instrument at the same time.

Older organs may also be restored to a previous state, including re-creation of damaged and missing parts using historically accurate materials and techniques.

In some countries, including Germany, Switzerland, and Norway, organ building is a regulated handwork profession.
