I wouldn't say its indefinable. We know the pitch drops - we know the structure is flexible, we know that the components of the piano are interrelated. My whole point earlier was "how could there possible be ONE cause?". How would one construct an experiment to accurately measure all the structural changes in a piano before and after a pitch raise? It would be necessary to detect and measure very small changes in the structure. We should definitely use some "lasers".
