Boston UP-125

$6,995

Available now – used Boston UP-125 — the predecessor to the current UP-126PE, 491/2″ upright piano. Rich bass, clear treble end and responsive action.

Boston uprights offer the same standards of excellence which characterize all instruments designed by STEINWAY & SONS. 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.

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 7 mm dual tapered. Vibrating area: 1.07 m2 (1,659 in2). Closing rim evens out the soundboard’s response to all frequencies, eliminating “hot” spots. Emulates shape of grand soundboard.

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 liner to support the important soundboard crown and prevent the piano from losing its tone. Number of ribs: 11

Bridges

Treble: Solid maple, curved to fit the crown of the soundboard. Bass: Solid maple mounted to cantilevered base. Doweled, glued, and screwed to soundboard. One continuous base and treble bridge.

Strings

Treble: Highest grade steel (in half size increments). Number of sizes: 12. Lowest tenor note: 28. Bass: Steel core wire wound with solid copper. Number 1 speaking length: 117.3 cm (46.2″)

Hammers

Premium wool topfelt over premium wool underfelt. Weight of topfelt: 9.4 kg (20.8 lb). Compression-wired to retain permanent shape. Mahogany moldings. Hammer-shanks from select resilient maple or horn-beam. Computer-designed pear-shaped hammers with reinforced shoulders result in superior tone, increased durability and greater voicing ability.

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.

Keys

Genuine spruce, individually balanced and weighted. Synthetic ivory and ebony key covers. Length of key: 36.8 cm (14.5″).
