Any new piano design tends to be judged in the light of the instrument, or instruments, that immediately preceded it or that surround it. Many early designs that we now consider to be obsolete were praised at the time -- and rightly so. Assuming, of course, that there was some improvement in the new design over its predecessors or its contemporaries. But that doesn't mean that they were flawless. And, yes, I think you are right, we do tend to judge older designs with our modern ears. But, shouldn't we do this? We certainly do with every other product we buy. You buy a car based on its improvements over the car you already have, for example. And we've (hopefully) learned something more about piano design over the past 150 years. We now know how to design out at least some of the problems that have plagued piano builders for decades. The particular design characteristic under discussion -- the foreshortened tenor bridge -- was considered to be a problem by at least two designers -- Wolfenden and Morton -- of the period between 1915 and 1920. That's some time back and they were already puzzled over why a practice they considered to be obsolete was still being used in "new" designs. And they both expressed roughly similar thoughts on the practice: they decried the weight of tradition, design laziness and ignorance. Not much has changed. Del
