Introducing the new Performance Edition II by Boston, featuring a Kewazinga Bubinga veneer on the inside rim (ebony pianos only), rose-gold plate color, black felts, and a rescaled bass and treble strings.
The Boston PE II builds on the best-in-class features that Boston is known for, including a Hard Rock Maple inner rim and Octagrip™ pinblock. At 5' 4" (163 cm), the GP-163 Performance Edition is small enough to fit in any home, but possesses the sound of a much larger grand — thanks to its widetail design.
Features and Benefits
The Boston piano features a duplex scale, adapted from the famous Steinway & Sons design, which adds a harmonic richness that simply can’t be duplicated by other instruments in a similar price range.
In comparison to other pianos, the Boston has lower string tension. This reduced string tension, along with a tapered soundboard, creates longer sustain, and a more singing quality in the tone (as well as longer piano life). A wealth of other engineering enhancements, including optimal placement of ribs, braces, and bridges, also contribute to the Boston’s superior tone and greater stability.
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.
Each Boston piano soundboard is crafted of Sitka spruce, long proven to be the most resonant material available. Boston soundboards are solid (not laminated) and precisely tapered, which allows them to vibrate more freely. In conjunction with a number of special technologies — unique patents of Steinway & Sons — the result is a powerful, sustained tone.

Hard Rock Maple inner rim -- this is the foundation of the Boston’s tone. Besides providing superior structural integrity to the piano, it enhances tone by being a rock hard foundation for the soundboard. A Maple rim is found only in the finest pianos. Continuous bent rim. 11 outer rim laminations, 17 inner rim laminations. 23mm (⅞") outer rim width, 38mm (1½") inner rim width.
Radiating braces solidify the piano’s structure. Their triangular layout provides more support than parallel designs. This rigid system improves tuning stability and soundboard crown retention, and lengthens piano life. 3 braces.
Octagrip pinblock made of 11 layers of Hard Rock Maple — glued in different grain angles of 60 degrees — affording the tuning pins greater stability under tension and enabling the piano to stay in tune longer.
Close and straight-grained solid (not laminated) Sitka Spruce. Minimum 3 annual growth rings per cm (minimum 8 per inch). Tapered from treble to bass, allowing a greater freedom of movement in the bass, and stiffness in the treble, thereby creating a richer and more lasting tonal response. Tapered from 8 mm to 6 mm. Vibrating area: 1.15 m2 (1,776 in2)
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. Number of ribs: 10
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.
Overstrung; combination of agraffe, with front and rear duplex. Rescaled bass and treble for lower tension scale for increased sustain, better tone clarity, and deeper clearer bass. 17,251 kg (38,032 lb) tension.
Cast from grey iron, bronze-painted and lacquered. Vacuum cast.
Treble: Highest grade steel (in half size increments). Number of sizes: 13. Lowest tenor note: 27. Mapes Bass Strings: Steel core wire wound with solid copper. Made by Mapes in Tennessee, U.S.A. Note 1 speaking length: 119.4 cm (47").
Premium wool topfelt over premium wool underfelt. Weight of topfelt: 9.5 kg (20.9 lb). Compression-wired to retain permanent shape. Mahogany moldings. Tapered hornbeam hammershanks. Computer-designed pear-shaped hammers with reinforced shoulders result in superior tone, increased durability and greater voicing ability.
Solid maple and hornbeam (all wood, no plastic) for all moving parts. Steinway profile-shaped flanges, extruded aluminum action rails for increased stability and less frequent regulation. Steinway action geometry provides superior touch.
Genuine spruce, individually balanced and weighted. Synthetic ivory and ebony key covers. New synthetic ebony has ebony-like surface texture and appearance that absorbs perspiration from the fingers. The fine synthetic ivory of the white keys has the same properties of friction, porosity, conductivity, and appearance as ivory.
Heavy solid brass castings. Soft, full sostenuto and damper (sustaining).
Classic case design. Coved toplid and keyslip, square arm shape with matching square fallboard shape, and wall cornice detail are all classic and beautiful. Violin-shaped topstick.
- Fallboard: Soft fall fallboard.
- Casters: Heavy-duty double-wheel solid brass casters.
- Locks: Fallboard and top locks.
- Prop Sticks: Double top prop sticks.
- Bench: artist, adjustable bench (cushion, adjustable height) for all ebony finish pianos.
- Black Felts for Plate, under Fallboard, and around Pedals on Lyre.
