Stability of the Tuning of Organs

Summary/Abstract: The article is concerned with stability of the tuning of historic organs which have their wind system supplied, in terms of the positioning of the instrument itself, from an external environment. It addresses the question of temperature changes in sacred buildings, which are an essential magnitude for the analysis. The analysis also touches on the mode of construction used for the wind system, since this construction has a fundamental influence on the constant change of pressure and air temperature in the wind system. We have verified the entire analysis in situ under real conditions, also by means of an experiment regarding the analysis of tuning. The positioning of the wind system, sucking in air which differs in temperature from the air where the instrument itself is positioned, does not have any destructive effect on the tuning of historic organs and hence does not damage this tuning in any way.
