Pramupega: The Organ, Opened Up

Field notes

The project organizes organ-building around the movement and control of air, beginning with a centrifugal fan and reservoir bellows before reaching the windchest and pipes. It explains pressure in millimetres of water column and connects small pressure changes to voicing and tuning. The material also identifies practical failure signs, including leaking wind channels, hardened bellows leather, unstable pitch under load, and motor noise transmitted through the case. Later sections cover alloys, wood, scaling, reed construction, transmission, and seasonal maintenance.
