155 Bosendorfer Baby Grand Piano

Bosendorfer 155

5'1" Baby Grand Piano

Introduced in 2012, the 155 Bosendorfer Baby Grand Piano is designed to delight players who refuse to compromise their artistic expression and freedom of articulation, but lack the space for a larger instrument. Despite its diminutive cabinet, this piano is capable of immense dynamic control and color - far more so than is typical for baby grand pianos of this size. Bosendorfer's artisans have accomplished this by building 85% of the piano out of Bavarian Spruce tonewood. Even the piano's rim and frame are made with solid spruce. Much like a fine violin, this gives the entire piano a role in tone production - unlike other instruments whose manufactures think of the piano's frame and rim as purely structural or decorative in nature. This "Spruce Resonance Case" is made of only the finest Bavarian spruce and is naturally dried for five years before use. The piano is then fitted with a custom cast iron plate, individually-attached strings, hand-wound (bass) strings, an open pin block (for unparalleled durability and tuning stability), the same custom Kluge keyboard used in the larger model 170 and a custom Renner action - the finest made in the World today.

The entire process takes six years to complete, but the result is a baby grand with an extraordinary spectrum of colors and the responsiveness of a concert instrument.

Rich tonal color, projection of enchanting nuances, repetition speed and a responsive touch are key qualities of a Bosendorfer grand piano. These same tenets guide the construction of even the 155 - the smallest Bosendorfer baby grand piano.
