Details of the Steinway Model D Concert Grand Piano are...
The one-piece continuous bent rim, 3¼” thick, is one of the most significant technical innovations in piano building. The rim provides the foundation for the beauty, stability, and quality of each Steinway grand piano. The rim of the Steinway Model D is comprised of 17 layers of hard rock maple — with both inner and outer rim being pressed together in a single operation — which provides the structural integrity that enables a Steinway piano to endure for generations. This unique rim construction has been an integral part of every Steinway grand piano since it was developed and patented by Steinway & Sons in 1878.
Made entirely from hard rock maple; 17 laminations;continuous bent, both inner & outer form one single rim; unequalled strengthened stability. Thickness: 3 1/4" (8.26 cm)
5 solid spruce with a volume of 2,907 cu. In. (47,637cm3);Spruce provides tensile strength with less weight. Maple dowels fasten braces to rim producing a single homogeneous foundation upon which is built the entire tonal component. A cast iron treble bell, affixed to rim`s underside at treble bend, holds plate firmly in position by means of a steel bolt. The S & Siron wedge anchors brace ends securely to cross block assuring permanent rim posture.
Hexagrip patented design; 7 laminations of quartered hard-rock maple stock. Grain symmetrically distributed at successive angles of 45, 90, employing grain direction uniformly around the circumference of the tuning pin to provide the ultimate in pin grippage. As a result of this exclusive design, the tuning pin has smoother movement under torque, a more uniform retaining action for solid setting, and a piano which will hold its tuning longer.
The soundboard lies at the heart of a Steinway grand or upright piano, which is why great care is needed both in its design and in the selection of the wood. To meet the highest quality standards, only superior Sitka spruce with a regular grain and prescribed minimum number of annual growth rings is acceptable. The production of the Steinway Diaphragmatic Soundboard is based on a 1936 patent to achieve optimum performance in dynamic range and maximum sustain. Under this patent, the soundboard is gradually tapered from the centre to the edge, permitting freedom of movement and creating a sound of unparalleled richness, sonority, and sustain.
Created like the soundboard of violins to give a free and even response throughout the entire scale, it is so constructed as to be 9 mm thick in the centre and tapered to 6 mm as it approaches the rim and outer case before being DOUBLE CROWNED. This design permits complete freedom of movement,while acting as a homogeneous unit to displace a greater amount of air, there by creating a richer and more lasting tonal response. Close-grained, quarter-sawn Sitka spruce, a wood having unusual stability and vibrance under stress and vibration, is used exclusively for the soundboard.
Made from durable, resinous sugar pine to assure strong and constant support of string down-bearing on the soundboard. Rib ends are hand-fitted into their mounting surfaces virtually locking in the important soundboard crown.
The better the materials, the better the sound. Steinway & Sons construct its soundboard bridges exclusively from vertically laminated hardwood with a horizontal grain, capped with solid maple. Each bridge is notched by hand for precise, individual string-bearing. This design ensures optimal sound transmission from the strings to the soundboard, resulting in a sustained, resonant tone—creating the inimitable Steinway Sound. In 1963, Steinway introduced the Hexagrip Pinblock, which is engineered to enable pianos to hold their tuning longer and with incredible precision.
Treble: Hard rock maple vertical laminations capped with solid hard rock maple; planed to prescribed height, graphite coated, drilled,and notched by hand for precise individual string bearing. Design defies splitting. Bass: Continuous with treble. Maple dowelled, glued, and screwed to soundboard.
Overstrung; combination agraffe; Front AND rear duplex. Tension: 45,373 lbs. (20,418 kg)
Up to 20 tons of string tension is being exerted within a piano at all times. It is the function of the cast iron plate to accommodate this extraordinary force and provide strength and stability throughout the life of the piano. Steinway & Sons uses its own 'bell-quality' casting to support this string tension and reduce vibration, which in turn enhances the sound. This component is so integral to the construction of a Steinway piano that Steinway & Sons owns and operates its own foundry, which produces cast iron plates to its exacting specifications. The plate is sturdy grey iron; filled, CNC–milled, and sealed; bronzed and lacquered.
Premium blued steel with rust-resistant, nickelled heads.
Treble: Twelve whole & one-half sizes from high-tensile Swedish steel. Bass: Swedish steel core wire wound with pure copper. Longest, Agraffe to bridge: 79 1/4" (201 cm)
Premium wool top felt over premium wool under felt; treated to resist insects and moisture. Compression-wired to retain permanent shape.Hard rock maple hammer mouldings and shanks.
Horizontal-cut premium wool for effective dampening. Maple heads for endurance.
White, quarter-sawn maple parts are bushed with specially treated wool action cloth for freedom from friction. Parts are anchored in hard maple dowels housed in inflexible seamless brass tubing to assure precise &stable regulation. Exclusive single, combination phosphor bronze repetition& fly spring provides constant, crisp touch response. Specially designed to respond 14% faster fortissimo & 6% faster pianissimo by using an exclusive combination of half-round balance rail bearings and strategically placed keyleads.
European spruce, individually weighed-off. Chip-proof,stain-resistant coverings for naturals; slip-proof, delicately abraded ebonized sharps. Tough, durable Lindenwood buttons reinforce keys over balance rail permitting maximum tonal power with every strike. Longest: 24 1/2" (62.2 cm)
Made from planks of stable, quarter-sawn spruce. Horizontal planks are freely mortised together, while their ends are permanently mortised into vertical planks made of birch, presenting a vented system for humidity escapement while allowing for necessary expansion and contraction. Front centre is crowned contrasting the reverse-crowned action frame for snug fit. This design intensifies key movement and prevents "slapping" during heavy playing. Large maple dowel ends provide a solid mount for adjustable brass touch-regulating screws. Thickness: 1 3/4" (4.45 cm)
Heavy, solid brass.
Soft, Sustaining & Full Sostenuto.
