FONT-FAMILY: Arial; BACKGROUND-COLOR: #ffffff"> <DIV> <DIV>Del, David, Ric, list,</DIV> <DIV> </DIV> <DIV>It is probable that the 7'2" built in the late 1860s and 1870s was tuned upwards of A457.  That's 2/3 of a half step sharp by our A440 standards. </DIV> <DIV> </DIV> <DIV>Wire of the time was less stiff, more ductile, and had a significantly lower breaking strength.  It was going through a period of change, as breaking strengths and stiffness increased, pitch was increasing too, probably to ensure brightness with increasingly stiffer wire.  For 15 years the 7'2" stringing scale remained the same while the wire itself went through a metamorphosis.</DIV> <DIV> </DIV> <DIV>Typically in this model A85 is 46mm long.  Too short for modern wire.  The Steinway inventory journal shows both Poehlmann and Webster wire in stock during this time;  it's possible Webster was being used for the top, as Poehlmann's wire was becoming stiffer and might not have worked as well....although at the higher tensions it may have worked fine clear to the top.   </DIV> <DIV> </DIV> <DIV>Modern wire (Roslau, and especially Mapes)  is far too stiff for the top two octaves of this scale, even when tuned to A457 (though it sounds better than at 440).  I'd love to find some cast steel wire annealed to fit the original scale of the Steinway;  this might come closer to the wire originally used.</DIV> <DIV> </DIV> <DIV>I had an 1877 Style II in my shop on consignment this last year.  This piano had been rebuilt 20 years before, a straightforward rebuilding of the time.  It had a very substantial, powerful sound except on top where the lengths were shorter.  I restrung the top 1.5 octaves with Pure Sound stainless wire (Juan Mas Cabre did the scale work), which brightened up the top some. That's a good start.   </DIV> <DIV> </DIV> <DIV>I believe it's worth the effort to try to get at what the original designer had in mind too.  We will learn far more from these pianos if we make a sustained effort to document these pianos, conserve some for study, restore others to functional originality, and make replicas or remanufacture in a replica manner..</DIV> <DIV> </DIV> <DIV>I understand that by increasing the speaking lengths and using modern wire we're also trying to do this, but we're fundamentally changing the physical dimensions of the instrument;  we're altering the physical document forever.   </DIV> <DIV> </DIV> <DIV>It was one thing for Steinway to retrofit an action in 1872 on a ten year old piano, as the company was inclined to do;  it's quite another for you and I to do these things today.</DIV> <DIV> </DIV> <DIV>The time has come for our trade to begin to take seriously the need to conserve these older instruments.  Even the somewhat plentiful 7'2" Steinway through 1878 is not yet well documented, and relatively little is known about it.  Most have already had modifications (at least restringing, often action replacement) and so these things are already partly lost as original documents for serious study.   </DIV> <DIV> </DIV> <DIV>As piano technicians we need to be aware that our role as consultants and experts places us in a position of real influence with these historical instruments...people look to us for guidance, when it might be more responsible if we referred them to conservators of keyboard instruments.   However, one of the reasons we feel free to permanently alter pianos of the period through 1880 is that music historians and even keyboard curators don't seem to think this period is very important (or that everything that came before was more important, and this period really is just the less-important modern period).  So we haven't been made to feel the pianos of this period are any more than transitional PSOs (one prominent researcher called early Steinways pretty boxes with strings), and what was important was what was before...and after...this period.   But these instruments are very important....and we won't truly understand them until we actually make them the object of continued, disciplined study in their own right.</DIV> <DIV> </DIV> <DIV>Another reason we aren't so impressed with pianos from this period is that we make assumptions about how they once sounded based on how they sound today...or we make judgments based on how today's stringing materials sound in these old pianos which were designed for string material that doesn't exist today..  Even if the soundboard structures were healthy, the more ductile cast steel wire of the 1860s and 70s was still capable of fatiguing and work hardening, and doesn't stand much chance to retain its brightness and ductility, especially the wire in the high treble.  And in the high treble the original wire might be the only wire capable of really sounding good on the piano, since modern wire is too stiff for the short high treble scale.   So we increase speaking lengths to accommodate modern wire, while a study of the original wire might result in a conservation or restoration which would be the best way to get at what the piano truly sounded like.  There are enough 7'2" and 8'5"/8'6" instruments out there still (these two lengths shared a similar design and history);  it would be worth the trouble to get cast steel wire with the physical characteristics of the period, because we'd likely be astonished at the result with these instruments.</DIV> <DIV> </DIV> <DIV>I inspected an 1860 8'3" flatstrung Steinway which was truly an amazing instrument.  "Truly amazing" doesn't seem to fit most of our experiences with the typical 7'2" Steinway of 1878 and earlier, but I believe this model was just that in its original form, and we should try to get at it, try to get at the real truth of it, before it's lost to history.</DIV> <DIV> </DIV> <DIV>I'm not saying Del shouldn't design new soundboards for a few of these, but I think we've neglected the study of these pianos, and we're running a great risk of missing out on the unique greatness of these instruments.  The original greatness, as the builder intended.  Complete with their design idiosyncrasies.  The convention in Kansas City will have a half-day seminar on piano conservation (the first two CAUT periods) where I hope we can begin to understand the work of the conservator as it could impact our trade, and I hope that continued discussion will result in guidelines which piano technicians may refer to when dealing with pianos from this earlier period.  The best way for the PTG to do this is to begin to network with professionals in keyboard conservation (and the American Institute of Conservation, AIS) and the folks with the American Musical Instrument Society (AMIS), who value historical instruments in their own right.  So the first period will be a lecture by Laurence Libin, who was keyboard curator at the Metropolitan Museum of Art for 33 years and very active in AMIS.  He now has a desk at Steinway and Sons by virtue of his extraordinary lecturing abilities on the history of the piano;  I heard him lecture at Steinway last May for three hours, and suggest you don't want to miss his 1.5 hour class on conservation at Kansas City.</DIV> <DIV> </DIV> <DIV>In the meantime I continue to roam the country for pianos to document and study (as budget allows), and I welcome the opportunities which come my way to combine site visits to document early Steinways with chapter programs or all-day seminars on the early Steinway grand....see <A href="http://www.periodpiano.org">www.periodpiano.org</A>   Piano technicians know better than anyone else where the pianos are...and are in the best position to influence owners, when armed with good information.   In February I will be in Fresno CA to document the same Centennial grand which was used in Cynthia Adams Hoover's influential monograph, "The Steinways and their Pianos"  (it had been on loan to the Smithsonian when she studied it).   Later in the spring I will inspect the 1857 8' instrument at the Smithsonian which she also includes in her study.  It's time for a second, more extensive look at these key examples of the scholarship of early Steinways.   Hopefully as the protocols for documentation become more sophisticated we'll have an extensive database of reliable data which will help us to understand far better what these pianos are all about.</DIV> <DIV> </DIV> <DIV>Bill Shull</DIV> <DIV> </DIV> <DIV> </DIV> <DIV> </DIV> <DIV>Bill Shull</DIV> <DIV> </DIV> <DIV> </DIV> <DIV> </DIV> <DIV> </DIV> <DIV> </DIV> <DIV>  In a message

Del<BR><BR>It would seem to me that raising tension or not on an older instrument <BR>has a natural structual limit of safety.  As long as you hold yourself <BR>safely within these boundries I would

No roll, or flexing of the area we'd usually call the <BR>stretcher. Nor do I find any real sign of structural strain in the rim <BR>and bracing. This thing had a total of just over 13000 kilos tension if <BR>modern string specs are used to figure tension. Roughly 29000 lbs. I'm <BR>probably going to increase that slightly to about 14000 kilos and most <BR>of the increase will be coming at the top of the scale.  The present top <BR>note #85 is at 48 mm long and it will probably end up around 50.5-51.  <BR>Most of the top octave will increase slightly, and a few scattered notes <BR>to even out some humps here and there.<BR><BR>This is also getting a new soundboard and design.  The basic design is <BR>the same, but I've introduced some crown into the system using a 3 ply <BR>laminate setup in which crown was establised as part of the lamination <BR>process.  Otherwise.... the thing remains very close to the origional. <BR><BR>I'm doing a bit of experimenting with ideas here to be sure... but <BR>essentially I'm hoping to give it a slightly more modern treble that <BR>gradually moves towards the original bass sound (which I have always <BR>liked).  The middle ply is thinned so as to take care of the original <BR>thinning of the soundboard as a whole. This also very gradually lessens <BR>the crown and crown strength I've introduced into the treble. With this <BR>I hope to be able to also introduce a bit of downbearing in the upper <BR>regions of the scale. More then likely the thing was pretty much strung <BR>without any downbearing at all. The original rib orientation would offer <BR>little support thus.  So a tad more tension... a bit more downbearing <BR>coupled with a bit more stiffness and strength from a panel that shows a <BR>non-linear spring rate...<BR><BR>Well... we'll see how it turns out.<BR><BR>Cheers<BR>RicB<BR><BR><BR>    I'm remanufacturing one of the early Type I (85-note, 8' 5") grands<BR>    right now.<BR><BR>    There was no sign of stretcher/pinblock structural failure.
