The piano certainly has more power, but when pushed (played big >and hard and loud), it gets too brassy too quickly. It is a common misconception that one can add more "power" to a piano by voicing and/or adding lacquer or some other chemical hardener to the hammer. None of these processes actually add any power to the acoustic output of the piano. They simply change the make up of the energy spectrum set up in the string. That is, the energy spectrum set up in a string by an impact from a relatively soft hammer will have relatively more energy in the lower partials relatively less in the higher partials. An impact by a harder hammer will set up more energy in the higher partials and somewhat less in the lower partials. The actual amount of sound energy produced by either won't alter much, if at all. The harder hammer will appear to produce a louder sound only because the amount of energy in the initial impact sound will be greater and more of it will be in a higher frequency range. Since energy in the higher partials transfers into the soundboard and dissipates at a more rapid rate, this change comes at the expense of sustain. It also comes at the expense of tone quality. So you pays your money and you takes your choice -- there ain't no such thing as a free lunch here. In general, the tone quality of modern pianos has become harder and brighter over the past couple of decades. In part this is because it is easier to build pianos in very high production this way. Since it is an axium of marketing strategy that when one is confronted with a "bug" or a design defect the best solution is to call it a "feature" and raise the price, a great deal of marketing effort has gone into convincing the piano world that this is all a very good thing. Sadly, this doesn't really make it so and much musicality has been lost along the way. >So, at least a couple of my questions are: > >Has anyone been successful in getting this piano to be more powerful (along >the lines of the Steinway), without overstepping the boundary into tinny-ville? Yes, this could be done. All you would have to do is change the stringing scale to match that of the Steinway, replace the soundboard with one designed and shaped like that of the Steinway, install and shape and heavily lacquer/acrylic a set of Steinway hammers, etc. You might have to do a bit of rim work and plate work as well. It might be simpler and cheaper in the long run to simply buy a Steinway. >Is the Grotrian better at that round-mellow (European) tone, rather than >trying to compete with the Steinway sound? How's that for a generality (but >it does seem to me that the Steinway Concert Grand is the benchmark for >many people's ears:-)? Yes. In my opinion at least, it will be better to let the Grotrian be a Grotrian and spend your effort trying to educate the pianist to appreciate the value of tonal subtlies. And as far as the Steinway Concert Grand being the benchmark for piano sound...what year were you refering to? The tone quality of the SCG being produced today bears little resemblence to that of just a few years ago and even less to that of some decades back. It would appear that these pianos are now trying to emulate the hard, brassy sound that the marketing people seem to like so much. Unfortunately those tastes don't always have much to do with music. -- ddf
