Hi All,  In my on-going pursuit of knowledge, I ask that anyone
possessing any scientific studies on the factors that effect the
stability of a piano tuning, please forward those studies to me
or tell me where to find them.

Any references are acceptable as long as they are from a controlled
study, the results of which have been published by a major university,
piano company or well-known and/or respected author.

Thank you,

John A. Tuttle (john@player-care.com)
