Its automatic that all essential instruments such as these are tuned the first week of school or thereabouts. We look for a near draconian drop in the temperature that will force the moisture content out of the outside air, and very shortly after the same will occur inside the building. Every year we pray we this drop (below zero) to occur the week of Christmas break. If we were to tune before this happened all evidence that the instrument had been tuned would disappear. A good solid tuning that takes place after the drop will remain good for close to four or five months. Likewise the same type of change that reverses the process will occur around the the first of July. Have a good holiday!
