Boston GP163

In stock

The Boston grand piano offers a larger soundboard in comparison to other pianos of the same length, due to its innovative “wide tail” design. This wider construction of the case means that a 5’ 10” Boston grand has the same soundboard area as a typical 6’ 2” grand piano, creating the power, richness, and feel of playing a much larger piano.

“You can hear the effects of the Steinway & Sons design from one end of the scale to the other. No piano in the Boston’s price range comes close. Believe me, I’ve listened to them all.”

– Bob Winter
Professor of Piano, Berklee College of Music

When you first touch the keys of a Boston piano, be prepared to experience an entirely new sensation. Unexpected power suddenly fills the room. You immediately notice the rich fullness of the sound. The keys respond almost intuitively to your fingers. But, because it was designed to take advantage of the efficiencies of high technology manufacturing, the Boston is also remarkably affordable. It’s understandable that no piano in modern history has ever made itself heard so immediately, or so dramatically.

Specifications and Features:

Boston grand pianos are wider, particularly at the tail or back, than other pianos of the same length. This allows a bigger soundboard area, producing bigger sound. Lower-tension scaling for longer sustaining tone, and longer life of the whole piano. Duplex scaling adds harmonic richness and longer sustain to the tone.

Solid (not laminated), straight-grained Sitka spruce with a minimum of 8 annual growth rings per inch (3 per cm.) for proven superior tone quality. Tapered, rather than uniformly thick, to vibrate more freely and provide more volume. Specially designed closing rims make the soundboard irregular in shape, and improve its acoustical properties. Soundboard ribs are of spruce and are fully let-in to notched liner (uprights) and rim (grands) to support the soundboard crown and prevent the piano from losing its tone.

Vertically laminated with a solid maple cap in grands, and reverse crowned in uprights and grands, to create better transfer of sound from bridges to soundboard.

Pinblock and Tuning Pins
Wisconsin Hard (Rock) Maple, laminated multidirectionally, grips tuning pins from several directions to assure a tight fit, uniform pressure, and smoother tuning. Nickel-plated blued steel resists rust and enhances appearance. Cut threads create hundreds of teeth that grip the pinblock and keep the piano in tune longer.

Bass strings wound with solid copper, and Roslau treble string wire of the highest grade Swedish steel provide superior tone. “Overstringing” allows maximum speaking length of bass strings.

More powerful, longer sustaining tone.

Plate and Finishes
Cast from gray iron to the most precise tolerances. “Over-engineered” to provide strength to support 20 tons of string tension. Cabinet parts finished in a wide variety of natural wood veneers with durable polyester or polyurethane top coats.

All wood (no plastic) for proven durability, faster repetition, and heightened responsiveness and control. Rosette-shaped, extruded aluminum action rails and flanges mean increased stability and less frequent regulation. Computer-designed, pear-shaped hammers with reinforced shoulders deliver optimum performance from the Boston piano scale design. Piano keys are spruce, and are individually balanced and weighted.

All wood used for making parts is naturally cured and kiln dried to the precise moisture content specified, to assure precision and long life. Grand piano rims and upright case components are laminated Philippine mahogany, for stability, strength and long life. Computer-designed radiating grand braces of laminated Philippine mahogany provide stronger, triangular support compared to parallel designs. Uprights similarly employ staggered backposts. This rigid support increases tuning stability, soundboard crown retention and long piano life.
