The Semi-Concert Grand
The Mason & Hamlin Model BB represents one of the finest semi-concert grand pianos available today. Measuring nearly seven feet in length, the BB combines extraordinary musical power with the craftsmanship, engineering, and tonal richness that have defined Mason & Hamlin for generations.
For pianists seeking greater projection, expanded dynamic range, and exceptional tonal complexity, the Model BB offers a remarkable musical experience. Its larger scale design allows for enhanced bass development, increased sustain, and the broad palette of tonal colors that serious musicians often seek in a performance instrument.
The Model BB occupies a unique position within the Mason & Hamlin lineup, bridging the gap between premium home instruments and full concert grands. It is equally at home in luxury residences, teaching studios, churches, institutions, and performance venues.
A Performance Instrument Built Without Compromise
The larger dimensions of the Model BB allow the instrument to deliver exceptional musical authority while maintaining the responsiveness and expressive control that Mason & Hamlin is known for.
Musicians often appreciate the BB for its ability to produce both power and nuance. From delicate passages to demanding concert repertoire, the instrument responds with clarity, warmth, and remarkable sustain.
The result is a piano capable of filling larger spaces while still providing the musical intimacy and responsiveness that performers value.
