Del: Does it follow, then, that a heavier soundboard requires a higher tension scale? And then what happens when you put a higher tension scale on a lighter soundboard assembly? In the calculation of the tension of a scale is it important to consider the type of soundboard assembly? I notice in perusing Travis that the scale tensions probably vary quite a bit from piano maker to piano maker. Is that owing to differences in fundamental philosophy or soundboard assemblies? Lastly, in the calculation of tensions, is there a trade-off between power and sustain? Or are they unrelated? Inquiring minds want to know.
