All, Things have finally slowed down so that I may set down my philosophies regarding these instruments. The main thread was about Bird-Cage pianos, but, in my opinion, the philosophy should be the same. Having said that, I submit to you all how to approach these instruments. I would, first, ask you to reserve your conclusions and comments until I have finished and would also like to start with a story: Imagine that the time is 1890 and you have finally achieved stature in your community. You now have the ability to buy a house. You are engaged to be married. All is well with your world. Your fiancé has reminded you that, traditionally, the first item to go through the door of your new house, is, of course, a piano. So, it's off to the Piano Store, to select a suitable piano for your new house. When you walk into the Piano Store, you are greeted by the owner. You explain your situation to the owner and he guides you to a beautiful Grand piano. The owner extols the many features of the X&S Grand piano and invites you to try it. You only know a few songs, but agree to give it a try. As you play, you don't really hear what you were expecting and mention this to the owner. He thinks for a minute and then guides you to a beautiful "Modern" Upright piano with beautiful carvings and finish. Again, he invites you to try it out. Again, you don't hear what you want in a piano. Again, you explain to the owner, that this piano doesn't quite sound like what you were expecting. You add, "It really doesn't sound like the piano that I learned on....., it doesn't sound like my Grandmothers piano!" The owner raises his eyebrows a bit and then smiles. He leads you to another beautiful piano, but it is different. It is rectangle in shape and massive, with carved legs and a beautifully carved music desk. The owner calls it a Square Grand. As you play your music, your thoughts are filled with the wonderful times of your youth, with Grandmother at your elbow, encouraging and coaxing. You finish the tune and state: "I'll take it""Please deliver it to my home as soon as possible". The Owner smiles broadly and sets upon the paper work for the purchase. All is well in your world. Therein lies the reason for these instruments. Considering the basic law of business, supply and demand, is the basic reason for Square Grands and Bird-Cages. There was a basic demand for pianos that,.. "sounded like Grandmother's Piano". Consider, that Grandmother's piano was a early 1800's piano. Pianos of that period had not refined the technology of piano building. And, especially the technology of dampers. Anyone who has tuned/played on an early 1800's piano, will attest that the sound was "weak" by todays standards. The touch was very "light" by todays standards. The piano's damping system is not as efficient as modern counterparts. All these things lead to the distinctive sound of the Square Grand and the Bird-Cage pianos. In my opinion, the only difference between the early 1800's instruments and the Square Grand/Bird-Cages is the sound volume. The later is simply louder. The "Bird-Cage" piano was made by several Countries in Europe, but to my knowlege, not in the United States. The French made weird versions, that from my experience, were the worst of the worst of these type of instruments. The Germans made them for only a few years. I suspect from around 1870ish to 1880ish. They either didn't have the demand or simply, (in true German style), dismissed the Bird-Cage as a poor "Design" and ceased to make them. The English, on the other hand, made Bird-Cage pianos well into the 1930s. (I am amazed that the entire British Isles didn't sink into the North Atlantic by the sheer mass of Bird-Cages made!) In my opinion, the English Bird-Cage piano was the "Ghetto Blaster" of the 19th Century. They were, for the most part, cheaply made. The case was moderately ornate, but not a well done as the "modern" Uprights and Grands, being made in the same factories, at the same time. Basic construction was substandard by any standards. The Pin Block is the worst part of the majority of these instruments. It was made by simply butt-jointing blocks of dubious wood to the general dimension of a pinblock. Then they glued a thin plank, (usually pine) to the back. On the front of this "plank" they affixed a thin, (by standards of that day), cosmetic veneer. Many times they used the cheaper "Fish" Glue rather than "Hide" glue. "Fish" glue is almost as strong as Hide Glue, but is extremely susceptible to moisture break-down. All this coupled to a back and case assembly of pine that was sparsely braced, made for a light weight, (read Weak), assembly. To off-set this flimsy setup, the string scale, (if you could really call it that), was light tension. The only "up side", that I can think of, for this piano, was that the tone was light and "airy", much like the pianos of the early 19th Century.
