Straight from the horses mouth… some wise words here:
It isn’t a job for the layperson I’m afraid – the art of setting the pins must be performed with masterly finesse if the piano is going to stay reasonably in tune for another six months. It took the Sheffield piano tuner many years of practice to become adroit at this and there’s still room for improvement – I’m sure there always will be.
He is right about electronic piano tuning apps as well, in the last ten years they have improved dramatically, although developing a good sense of equal temperament is also a must. When it comes to piano tuning, regulation and servicing – leave it to the professionals! The Sheffield Piano Tuner is always happy to help.
