As I said, for my part I typically tell them some of the theories as to why different technicians may suggest their piano goes out of tune seasonally. Then I tell them that for the most part, they all contribute, but to suggest that there is one reason is overly simplistic and inaccurate. When a client sees that you as a technician are unwilling to accept answers just because the masses recite the same answers, they DO respect that. > > All the reasons you give are very technical.

There's a reason for that. They're simple (and inaccurate). I wouldn't be honest if I said I never used that explanation. At first because I didn't know any different - it's what everyone told me - later as an expedient. More and more, however, I find that if you want a simple answer that people understand, you simply need to say when humidity changes, all the wooden components of your piano change as well, they expand and contract with increasing and decreasing RH. Simple. Accurate. If they want to know more you can delve into the complexities, if not, you're all set. William R. Monroe -------------- next part -------------- An HTML attachment was scrubbed...
