Is humidity and dryness a concern for the pipe organ?
These environmental conditions can damage leather and wooden parts resulting in various wind leakages, valve failures and pipes that continue to play without the note being actually played. Moisture will result in metal parts rusting. This is noticeable on pipe tuning sleeves, screws etc. Excessive dryness in a church is caused by a modern fast acting heating system that dries out the air. Direct sunlight upon the organ will warp and crack and even fade the finish on the case work.
