The pinnacle of concert grands and the overwhelming choice of concert artists and institutions throughout the world.
Since 1853, Steinway & Sons has made the finest pianos in the world. The meticulous crafting and superior materials used in today’s Steinways give them a responsiveness and quality of tone that cannot be felt or heard in any other piano. Created by artisans committed to absolute perfection, the Steinway sets the world standard for sound, touch, beauty, and investment value.
Success requires commitment and passion—two qualities demonstrated in abundance by company founder Henry E. Steinway. Born as Heinrich Engelhard Steinweg in Wolfshagen, Germany, he completed his first piano in the kitchen of his house in 1836. The passion and craftsmanship evident in the creation of this first Steinway piano would become the time-honored hallmark of the company. In 1850, Steinweg—later Steinway—immigrated to America with his sons, and on March 5, 1853, Steinway & Sons was founded.
With up to 20 layers of North American Hard Rock Maple in the one-piece, continuously bent rim, to the superior Sitka spruce soundboard, to each of the 12,116 component parts in a Steinway grand, each instrument is a work of art and beauty that will withstand generations of the hardest use and provide enjoyment for the most discerning ears.
The one-piece continuous bent rim is one of the most important technicalinnovations in piano building. It is the rim that provides the foundation forthe beauty, stability, and quality of each Steinway grand piano. The rim is comprised of up to 20 layers of hard rock maple—with both inner and outer rim being pressed together in a single operation. The unique one-piece continuous bent rim construction has been an integral part of every Steinway grand piano since it was developed and patented by Steinway & Sons in 1878.
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 an innovative patent to achieve optimum performance in dynamic range and maximum sustain. Under this patent, the soundboard is gradually tapered from the center to the edge, permitting freedom of movement and creating a sound ofunparalleled richness, sonority, and sustain.
THE BRIDGES AND PINBLOCK
The better the materials, the better the sound. Steinway & Sons constructs 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. The Steinway Hexagrip Pinblock, based on an innovative patent, is engineered to enable pianos to hold their tuning longer and with incredible precision.
THE CAST-IRON PLATE
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.

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 homogenous 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 & S iron wedge anchors brace ends securely to crossblock assuring permanent rim posture.
Hexagrip patented design; 7 laminations of quartered hardrock 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.
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 center 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 homogenous unit to displace a greater amount of air, thereby 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.
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 doweled, glued, and screwed to soundboard.

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 key leads.
European spruce, individually weighed-off. Chip-proof, stain-resistant coverings for naturals; slip-proof, delicately abraded ebonized sharps. Tough, durable Linden wood 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 center 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)
