Organ servicing always comprises
the tuning and maintenance of the organ.
Part 1: Tuning
An organ should be tuned „as little as possible“ and „as much as necessary“. For this reason, we do not recommend an overall tuning every year. For high-quality organs, the overall tuning can be limited to once every four or five years. In the in-between years, a partial tuning will suffice. Of course, these time frames will be set individually for each organ and also in compliance with the requirements of the parish.
• control and/or correction of the tempering
• intonation balance of single pipes
• tuning of all pipes that need to be tuned while maintaining their original tune colour
• retuning of single pipes that are very much out of tune
• tuning of all tongue registers
Part 2: Maintenance
The organ maintenance comprises the following tasks:
• examine the wind supply: check the oil level and possibly refill special oil
• check the secondary voltage of the rectifier
• check and possibly adjust the wind pressure, check the wind-chest bellows springs
• examine the instrument for traces of dirt, cement, humidity, signs of excessive draught and other damaging influences. The customer will be notified in writing of any damage noticed.
• Remove loose dirt from under the pedal board and keyboards
• check all technical functions and the pipe reaction
• check and readjust the keyboard and register sections as well as the couplers
• remedy small damage and failures at the pipes, wind chests, bellows, wind channels and felt covers
• repair or exchange small parts, especially in the keyboard and register sections
• remove small objects that might have fallen into the organ casing and the pipes
If the repair of damage or failures involves major work considerably exceeding the regular time-frame, the customer will be informed, and a cost estimate will be elaborated. Example: removing a particular howling noise usually implies dismantling the pipe section concerned.
Basic Outline of the Organ Servicing Contract
An organ servicing contract for a particular organ will be based on a general agreement with the diocese or regional church of the customer. Legally, this will always keep you on the safe side!
