Piano Description

For more than a century and a half, the world’s most accomplished pianists have preferred to express their musical genius on Steinway & Sons pianos. The list includes the giants in classical, jazz, and popular music; the men and women who have shaped the world’s musical heritage. Today, more than 98 percent of the world’s active concert pianists choose to perform on Steinway pianos. The joy of playing and owning a Steinway piano, however, is not the exclusive domain of the virtuosi. Rather, it is a world open to all who share a love of music, fine craftsmanship and enduring quality.

That which distinguishes Steinway pianos, more than all else, is summed up in our dedication to a single ideal: make the finest pianos in the world. It has never entered our minds to compromise quality. Where some have substituted mass-produced, synthetic components to speed production or reduce costs, we apply technologies and new materials only when they provide proven enhancements in the piano. We adhere to these principles for one reason — compromise quality, and you risk the sound, the touch, and ultimately, the integrity of the instrument.

While we adhere to the traditional values of craftsmanship, Steinway & Sons has also consistently led through innovation. The very earliest pianos crafted by Steinway were distinguished by their inventive features — many of which helped define the modern piano. Today, each Steinway piano is a summation of our commitment to innovation. Each incorporates over 125 patented features and processes, including our patented Diaphragmatic® soundboard, Accelerated Action® and Hexagrip® pinblock.

A Steinway grand piano takes nearly a year to create. Nothing is hurried. Even the carefully selected woods that make up the rims, top, soundboards, and actions cure for months in our yard, kilns, and conditioning rooms before they stabilize at a rigidly specified moisture content. The rim of the instruments consists of layers of hard rock maple and with our bell-quality, full cast-iron plate, withstands the enormous amount of tension exerted by the strings. The finest acoustic-quality spruce is fashioned into the delicate curve of the Diaphragmatic® soundboard, which tapers gently from the center to the edge, assuring the full, rich Steinway sound.

Ultimately, the pieces — massive and delicate — come together through the interweaving of the craft and technology until the instrument is complete. However it is not a Steinway until voicing gives it the special quality that makes it unique. Here, every subtle nuance is drawn out by balancing and adjusting the keys and shaping, hardening or softening each hammer. In the end, the new piano is transformed from more than 12,000 individual parts into an instrument… and from an instrument into a Steinway.

Instrument Specs

Rim/Backframe

Back Frame Solid birch mortised foot-piece. Solid birch soundboard lining. Grand-type maple laminated closing rim; unequaled vertical strength and stability

Braces/Posts

POSTS: 5 FULL-LENGTH tapered solid spruce with a volume of 3,600 cu. in. (58993cm3); assures that backframe will remain straight and consistent and stable tuning. Strategically positioned with bottom ends tenoned into birch foot-piece for positive vertical alignment. Spruce fill-blocks between posts at top of backframe capped with solid birch backing board for positive horizontal alignment.

Pinblock

Hexagrip patented design; 7 laminations of quartered hardrock maple stock. Grain symmetrically distributed at successive angles of 45º, 90º, 135º and 180º employing grain direction uniformly around the circumference of the tuning pin to provide the ultimate in pin grippage. Pinblock also fully fitted to plate flange and doweled to case structure. 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.

Soundboard

Created like the soundboard of violins to give a free and even response throughout the entire scale, it is so constructed as to be 8 mm thick in the center and tapered to 5 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.

Ribs

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.

Bridges

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: Rock maple base cantilevered at angle for maximum resistance to string pressure. Maple doweled, glued, and screwed to soundboard.

Scale

Overstrung; twenty-six note bass/tenor break. Treble duplex. Tension: 37,500 lbs. (16,875 kg)

Plate

Premium steel with rust-resistant, nickeled heads.

Strings

TREBLE: Ten whole and one-half sizes from high-tensile Swedish steel. BASS: Swedish steel core wire wound with pure copper. Longest, pressure bar/bridge: 46 3/8" (118 cm)

Hammers

12.5-pound (5.66 kg) premium wool top felt over premium wool under felt; treated to resist insects and moisture. Compression-wired to retain permanent shape. Hard birch moldings. Shanks from select resilient maple.

Action

White, quarter-sawn maple parts are bushed with specially treated wool action cloth for freedom from friction. Parts are anchored in hard maple rails. Dependable, Direct-Blow design permits ALL parts of the action to lie above the brass capstan screws. Specially designed to respond 14% faster fortissimo and 6% faster pianissimo by using an exclusive combination of half-round balance rail bearings and strategically placed key leads.

Keys

Bavarian spruce, individually weighed-off for even touch. 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: 16 1/8" (40.9 cm)

Pedals

Heavy, solid brass. Soft, sustaining, and full sostenuto.
