BOSTON UPRIGHT PIANOS (designed by Steinway & Sons)
Boston uprights offer the same standards of excellence which characterize all instruments. A Boston upright will give you the same opportunities to express your musical skill as a grand.
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 less string tension. This reduced string tension allows for a larger, tapered soundboard, creating longer sustain, and 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.
Each Boston piano soundboard is crafted of Sitka spruce, long proven to be the most resonant material available. Boston soundboards are also 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.

| Scale | Overstrung: Lower tension scale for longer sustaining tone and longer life of the whole piano. 17,425 kg (38,415 lb) tension. |
| Soundboard | Close and straight-grain solid (not laminated) Sitka spruce. Minimum 3 annual growth rings per cm (minimum 8 per inch). Tapered from treble to bass, to provide a rich tone in the bass, and a brilliant and crisp tone in the treble, creating a well-balanced and lasting tonal response. Tapered from 9 mm to 8 mm. Vibrating area: 1.11 m2 (1,721 in2). Closing rim evens out the soundboard’s response to all frequencies, eliminating “hot” spots. Emulates shape of grand soundboard. |
| Action | Solid maple (all wood, no plastic) for all moving parts. Extruded aluminum action rails for increased stability and less frequent regulation. Dependable direct-blow design. |
