Jim, I am not sure about the chicken and/or the egg. The rooster must involved somewhere as well. Point is, I agree. The piano is a dynamic structure, and must be considered as such. That's why, for me, the frame of reference is not physical but philosophical. In that way, it is possible to account for the physical variations of different components from a position that depends on extrinsic, rather than intrinsic, criteria. That is, if the defining criteria of what works are musical, then a wider variety of physical characteristics can be considered at the same time. Sort of a poor man's applied calculus. Worst time I ever had was a chandelier. It resonated with F#. Which would be fine, except that I still have trouble getting an F# with which I am happy. Ah, well...
