How do I know if my piano tuner has done a good job?
This is not as easy to answer as it first seems. The tuner is listening to the sounds of the strings whereas the average person is listening to the piano as a whole. Unless you are able to accurately distinguish the ‘beats’ set up between different pitches then you will have to rely on the overall sound of the finished instrument – does it sound pleasing to your ears? If not, try asking your tuner why; a satisfactory answer might include either the condition of the sounding parts or the quality of manufacture. Look also at the professionalism of your tuner – if he appears businesslike, confident and disciplined then this is likely to be reflected in the way he tunes your piano. Try to choose a tuner who has been recommended to you by someone whose opinion you can trust or find a Member of the PTA. He or she will have passed a stringent test of competence.
