It easily finds its place in all types of interiors. It will surpass in sound other manufacturers, even for models of larger sizes. It is a quart-de-grand piano, which develops powerful and rich bass in a contained size (170 cm).
Bass bridges are continuous with treble and maple doweled.Handcrafted since 1853, Steinway & Sons pianos benefit from all the know-how of the German firm, for an unparalleled rendering.ĭid you know that a Steinway upright piano requires more than six months of work before it can leave the factories in Hamburg and New York? A quarter-grand piano with a personal and inimitable character Treble bridges are hard rock maple vertical laminations capped with solid hard rock maple they are planed, graphite coated, drilled and notched by hand for precise individual string bearing, with a design that defies splitting. The exclusive design provides the tuning pin with smoother movement under torque, a more uniform retaining action, and a piano that holds its tuning longer. Grain is symmetrically distributed at successive angles of 45º and 90º, employing uniform grain direction around the circumference of the tuning pin to provide ultimate pin grippage. The Hexagrip patented design features 7 laminations of quartered hardrock maple stock. In 1963, Steinway introduced the Hexagrip Pinblock, which is engineered to enable pianos to hold their tuning longer and with incredible precision. This design ensures optimal sound transmission from the strings to the soundboard, resulting in a sustained, resonant tone-creating the inimitable Steinway Sound. Each bridge is notched by hand for precise, individual string-bearing. Steinway & Sons constructs its soundboard bridges exclusively from vertically laminated hardwood with a horizontal grain, capped with solid maple. The better the materials, the better the sound. Close-grained, quarter-sawn Sitka spruce - which has unusual stability and vibrance under stress and vibration - is used exclusively for the soundboard. The design permits complete freedom of movement while displacing a greater amount of air, creating a richer and more lasting tonal response.

Under this patent, the soundboard is gradually tapered from the center to the edge, permitting freedom of movement and creating a sound of unparalleled richness, sonority, and sustain.Ĭreated like the soundboard of violins to give a free and even response throughout the entire scale, the Steinway Model B soundboard is 9 mm thick in the center and tapers to 6 mm as it approaches the rim and outer case before being double crowned. The production of the Steinway Diaphragmatic Soundboard is based on a 1936 patent to achieve optimum performance in dynamic range and maximum sustain. 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 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. Large maple dowel ends provide a solid mount for adjustable brass touch-regulating screws. Crowned and reverse-crowned action frame gives a snug fit, intensifies key movement and prevents “slapping” during heavy playing. Horizonal and vertical birch planks present a vented system for humidity escapement. Durable Linden wood buttons reinforce keys over balance rail, permitting maximum tonal power with every strike.
