Grand Piano 155


Mechanical Refinement at Limited Space

Refined


Our Grand Piano 155 has been designed to surprise at 5’1” by mechanical refinement in action, responsiveness of touch and repetition, with key characteristics of bigger Grands such as the 170. Designed in 2012, this Grand Piano soon found many followers who did not like to compromise artistic expression and freedom of articulation in an urban setting. The smallest of all Bösendorfer resonance cases already proves its ability to enchant the audience with an extraordinary spectrum of colours – keeping in mind the actual size of the instrument. Richness in colour, projection of enchanting nuances, repetition speed and responsiveness of touch are key qualities of a Bösendorfer Grand. This is why we have applied the same key characteristics we designed for the bigger Bösendorfer Grand 170.

Resonance Case Principle
Details
Very similar in principle to a violin the whole body - not exclusively the soundboard - supports sound formation. The actual core of the piano rim consists of a 10 mm quarter-sawn piece that is specially grooved by our craftsmen to allow it to be bent to the silhouette around the inner rim. This is unique to Bösendorfer. When a note is played, the integrated spruce components become acoustically active, forming a complete resonating body that allows the whole instrument to project your play. An outstanding richness of tone colour and our legendary pure and brilliant sound is crafted this way. This complex construction is part of the Viennese tradition of piano making.

From delicate pianissimo to splendid fortissimo

A Bösendorfer Grand shows optimal controllability. Developed in cooperation with artists and technicians our action is crafted to our own, refined specification. This action is built to transfer the finest articulation of masterful play. Controllability at play.

Unique bass strings
Details
All bass strings are spun in our unique Bösendorfer way. A steel core string is the basis for 1 or two layers of copper. The carefully spun strings are a substantial element of the warm and sonorous Bösendorfer bass

Independent Capo d’Astro
Details
Bösendorfer is the only piano manufacturer that applies a detachable and independent Capo d’Astro in the upper register. This is how we assure an utmost precise adjustment in the upper register guaranteeing the original Bösendorfer Sound for generations: Unique sound for more than one generation.

Traditional Sand Cast
Details
We are using the traditional sand casting to forge our frame. Our raw frames, produced in Austria, rest 6 months outside the factory. This is how all inner strain of the forging process are released allowing the frame to remain relaxed under 20 tons of string tension. Pure stability.
Icon
Open pinblock
Details
Tonal stability at its best: Our open pinblock consists out of 3 layers of 7mm quarter sawn maple, glued cross-grained to each other. Settled on a base of red beech this construction offers a firm basis for the pins tied with strings. The top layer is refined with a 1.5mm walnut veneer. Our open pin block: a sound basis indeed.

Individually stringing
Details
Each string is individually attached with a handmade loop. Over time this improves tuning stability and is particularly service friendly.
Icon
Nature
Details
The basis of each Bösendorfer Grand is spruce that is naturally dried by air and has proven to be the ideal tone wood. The four seasons, sun, wind and wide temperature differences gently prepare this wood for its final purpose: to resonate. At Bösendorfer we use more than 80% of spruce tone wood building our instruments, more than any other manufacturer. When you add the natural drying process to our manufacturing time, it actually takes 6 years until the Bösendorfer Grand arrives at your doorstep. Precious time, necessary to craft the unique Bösendorfer Sound.
