Piano builders in Vienna concentrated their attention on building grand pianos, as opposed to London makers who built small square pianos for the growing middle classes. Therefore, square pianos made Austria are quite rare. Seydel, though working in the city, was from Saxony and brought elements of a regional north German tradition with him, including inscribed red score lines on the five octave keyboard. This beautiful rectangular square piano has a case of mahogany and mahogany veneer with canted front corners. The instrument rests on four square tapered legs, above which are decorative brass plates. A silke panel beneath the strings conceals the key levers. There are two knee levers, the right operates the overdampers and the left modifies the tone of th epiano by placing cloth tabs between the hammers and the strings. The keyboard has 61 keys (FF-f3) with ivory naturals and ebony accidentals. The internal mechanism is an Anglo-German action with escapement. The hammer butts are mounted in brass Kapsels. The date 1792 appears on the oval nameplate, but the maker's label on the soundboard is dated 1795.
