It's important to remember that, for many years (decades) the production line was, in effect, a laboratory. That being the case, much depends on when something went through. There are too many variables to generalize too broadly. >As far as benchmarks, this discussion derives from the earlier one in which >we were talking about whether there was a recognizable Steinway sound or, >more specifically, whether one could recognize when one deviates too far >from that.

I think Fostle goes on at some length about how and why the tell tale sound developed. In any event, the nominally "distinctive" S&S sound has definitely morphed over time; especially since recordings and media reproduction have come to be so culturally important. Slonimsky has something so say about this, but I can't presently remember which book of his includes it other than the book was published in the late 1950s. >Statements like the Hamburg has a thinner, less driven top end are easy to >make but, again, how is it you arrive at that conclusion.

Both of these positions are generalizations which are subject to specific deviation; and, both are, in my experience, true...and, not true. >I think it's a little presumptuous to suggest that those who are in the >second group haven't been in the stage laboratory for years.

Just because an instrument is taken into the C&A pool does not automatically mean that it is the top of the heap. In fact, from an historical standpoint, many of the instruments that wind up in the overall C&A pool are there because it has been a relatively safe place in which to keep them. That is, they are problematic in one or more ways, and, since in many major markets C&A instruments are used in recording studios and garden parties as much as they are on concert stages, the problems can be masked in various ways. I remember on B in which, under certain climatic conditions, had bridge pins on the lower portion of the tenor portion of the bridge (that is, under the plate) that would lock up tight against the plate and kill that portion of the scale. The answer was simple, that instrument only went to studios in which the venue would keep the humidity and temperature very low. >Of the ones that do make it there, how long do they stay >there on average? Reports on this thread suggest that it's not that long, >maybe 5 years. That depends. In the old days, some instruments were maintained for well over 12 or 15 years. Now days, except for those "owned"/leased by rental companies, they are rotated out more based on depreciation than on any other issue. >So why are they retired then? As noted above, it's mostly depreciation and/or damage. > It's not because the key >bushings wear out or the hammers. No...definitely not the hammers...these days, unless the piano is pretty new, the hammers are shot within five years, sometimes much less. >It's because the bellies change and the >qualities that got them to the C&A level may not be present any more. While that may have been true at one time, it has not been the case since 1987, at least. One of the first things the Birminghams did when they bought the company was to liquidate depreciated stock that was still in service. This did a couple of very important things for them. First, it picked them up a very quick profit after purchase. Second, and, historically for our purposes, much more importantly, the completely cleared the decks of "old style" pianos ("old" as mostly in action, hammer and production changes). In one fell swoop, so to speak, they completely removed from the general public eye the historical sound, touch and response of what the piano had been for decades. What has followed since has been substantively different. > So >let's even go so far as to give the benefit of the doubt that these more >traditional methods will produce pianos at some percentage rate (relatively >low it would seem) that are nines on a scale of ten, the best performance >pianos to be found and will remain so for 5 years.

The recent experiences of a colleague >of mine as he reported it is, perhaps, one example of that. While I agree in principle, I also think it's important to note that, from a philosophical standpoint, one really cannot expect a world in which everything is 8's to 10's...if nothing winds up being a 1 or a 2, then there is nothing really present against which to compare.
