Greetings
I have seen/heard people writing/talking about how older Steinways are better than newer ones. But that doesn't jive with my own experiences with old and new Steinways (I like more of the new ones than the old ones), so I'm curious to fine out just how statistically valid the claim is regarding the old/new Steinway comparisons.
I think that the old/new comparison of instruments is one that should be made with a few caveats.
Firstly, when comparing an older instrument, (I’m assuming you are talking about ones that are 25 years or older), I think that it's important to realize what condition it is in. Has it been regularly maintained (tuning, voicing, regulating and wear and tear maintenance of parts etc.)? Has it been housed in a suitable environment, been abused?
My experience in general is similar to yours as far as older instruments go. They tended to be disappointing to say the least. However, I have played on some older instruments that have met the criteria I mentioned above and they were beautiful to play. Perhaps a comparison of a fully rebuilt instrument to a new one would provide a better result.
After all, any instrument that has superior materials and craftsmanship would hold its own new or used.
Though I do agree that the Steinway B's can vary from one to another quite a bit.
Yes, I have played on several Model D's, as well as perhaps two dozen B's and the variance between instruments within each model was surprising.
But, it's not a perfect science, as each instrument is unique (materials, craftsmanship) and each has something to offer.
"Individual character" is just another name for "inconsistency." "Consistency" by definition eliminates "individual character." FWIW, I've played 8 or 9 different Fazioli pianos, all sizes from sub-6' to the F-278 concert grand, 3 of which are F-228's, my favorite. I have found even more consistency among the Faziolis than I have from the Yamaha C-series. Still, I like the Faz more than anything else -- all of them have very wide ranges of expressive capabilities for their respective sizes, I feel they are intuitively predictable and entirely dependable, and I don't have to worry about quirks stemming from "individual characters" of the pianos. That lets me concentrate better on the music.
Do you think that the sound and performance of these instruments are commensurate with the higher price?
From my vantage point, I really don't want a piano to have too much "character" of its own, much less "individual character" that can deviate greatly from one piano to another within the same make/model. The "character" should be moulded by the composition and the pianist, not something imposed by the hardware.
I agree, however it's hard to get away from this idea of 'character' as each instrument is unique and will affect the resulting sound that is produced by the pianist.
Ultimately, one should choose the instrument that speaks to them regardless of the make and price (within your budget of course).
Everthing else becomes academic.
