Yamaha Tuning Instability

[Farrell]

My comments have been general because I have not seen the piano in months. You, Roger Jolly, Mark Wisner and others have asked some questions. These questions will help me to evaluate the piano. I will be servicing this piano in about two weeks. I was just looking for suggestions on what to consider when I do service it. I will record where it is sharp/flat/whatever. I will tighten plate screws. I will get some humidity information. After I have looked at it, I will post again with specifics.

Thanks for all the input so far.

Terry Farrell
