Model B Overview

The Model B(6’11”) is the ideal “dream” piano of most serious amateurs and professional pianists who either do not have the budget or the room for a concert grand Model D(9’). It is the only Steinway smaller than the concert grand that shares 100% of its design features–the single-piece “shepherd's crook” Continuous Bridge, the solid cast iron Treble Bell, and longer keys (21″) than any smaller Steinway model (19”).  It has often been called “the perfect piano” by both professional musicians and veteran piano technicians.

Maple dowels fasten braces to rim producing a single homogenous foundation upon which is built the entire tonal component. A cast iron treble bell, affixed to rim’s underside at treble bend, holds plate firmly in position by means of a steel bolt. The Steinway & Sons iron wedge anchors brace ends securely to crossblock assuring permanent rim posture.
