Soundboard 

The Boston grand piano offers a Solid, North American Sitka Spruce soundboard that is sourced from British Columbia and Alaska. Long proven to be the most resonant material available and used in Steinways for generations, Steinway believes that the most important contributer of the tone should also be the same in all Bostons. The soundboards are Precisely tapered to Steinway specification, allowing the Boston soundboards to vibrate more freely. Boston’s innovative “wide tail” design permits for a wider construction of the case of the piano - allowing for much more ‘speaking’ or resounding area. The wider construction at the rear of the piano means that this 7’ Boston grand has the same soundboard area as many concert grand pianos, creating the power, richness, and feel of playing a concert or symphony stage instrument. Boston GP193 6’4’’ piano has 2,284 sq inches of sounboard vibrating area.

Strings

Just like in Steinways, a low-tension string scale design gives a fuller, richer, warmer tone by allowing more of the lower partials to sing. A lower tension scale means less tension exerted on the strings, permitting for more sustain, more powerful, and much more dynamic range. It makes it much easier for the player to achieve the warmer, darker, richer tones as it is for the player to achieve the bright, powerful, thunderclap like tones.

Pinblock

A Boston Performance Edition exclusive, eleven layers of solid, hard-rock maple (used for its superior hardness, grain and stability properties) are glued in different grain angles of 60 degrees, keeping the tuning pins tight but allowing for fluid motion and enabling better quality and longer lasting tunings. Steinway has been using Hard-rock maple in their own Steinways since the introduction of the Hexagrip Pinblock back in 1936 - the success and importance of the material is also used in the Boston.

Ribs 

Made from durable spruce to assure strong and constant support of the strings bearing down on the soundboard. Ribs are fully let-in to the inner rim to support the important soundboard crown and prevent the piano from losing its tone. This all constructed of solid wood. Number of ribs on the GP-193 : 12

Bridge

The Boston GP-193 pEII Bridges
Treble: Vertically laminated (alternating maple and mahogany) with a solid maple cap, curved to fit the crown of the soundboard. Bass: Solid maple mounted to cantilevered base.

Scale

Overstrung; combination of agraffe, with front and rear duplex. Rescaled bass and treble wire for lower tension scale for increased sustain, better tone clarity, and deeper, clearer bass.

Plate

Boston Bronze plate

Cast from grey iron, Steinway’s own Boston bronze-colour painted and lacquered. Vacuum Cast.

Hammers

The Steinway-designed BOSTON hammers are based on Steinway’s Pear Shaped Hammer - which enhances the action touch by rewarding the player with a beautiful tone. The hammer is what hits the strings producing the vibrations that allow for the soundboard to vibrate and to enable the piano to sing - Steinway’s pear-shaped design is all about engineering, the shape and tension in the design allow for precision of tone produced.

Action 

All-wood action parts, solid spruce keys, synthetic ivories and ebonies, and excellent action geometry work seamlessly together to move the hammers to the strings and create an excellent action-touch. The beautiful tone produced by the
