I don’t know much about how pianos work so I have to rely on my nine year son to tell me when the piano needs tuning. The last time my tuner came he said that the action needs regulating but I’m wondering if my son would know the difference?
This is a tricky situation for you because you are pitting the immaturity of your son whom you trust, against the wisdom and experience of a trained technician who you feel may be suggesting unnecessary work to boost his income. Unless your child is an authority on the correct regulation and tuning of pianos, it is probably wise to trust your tuner to suggest ongoing maintenance and the likely interval between required tunings. Sometimes it is necessary to make adjustments to the action which do not show any improvements to the playing of the piano but which, if left, will eventually become apparent and even deteriorate into more serious and costly repairs. Your tuner is actually doing what you are paying him for – looking after your instrument and keeping it in the best possible condition regardless of whether your infant prodigy notices any difference. Look at it this way – if the tyres on your car need inflating, wouldn’t you just do that even if you didn’t notice any improvement whilst driving the car? Your PTA tuner is qualified to assess the condition of your piano and if you trust his judgement will maintain it well.
