Wim-- These are school pianos. They don't want to tune the pianos more than once a year if they don't have to. I have to leave them sharp at the end of August. If I lower them to A440, they need a pitch raise in Oct. or Nov., and then the tuning isn't as stable. Yes, they're paying me to tune the pianos to standard pitch, but if they're going to tune them only once during the school year, they're going to have to put up with a) pianos that are sharp in the mid-range from August until the heating system comes on or b) pianos that are flat in the middle from about November thru the rest of the school year. Every year I explain (to the same teachers) about humidity changes and why you can't expect a piano tuning to last the whole school year unless the humidity is maintained at the same level, and every year it goes in one ear and out the other. They just refuse to believe it's humidity changes. It must be the tuner's fault. One teacher even refused to pay for a tuning in November because he believed I hadn't "done it right" back in August. --David Nereson, RPT
