Bosendorfer Collector's Items

Contrary to all other manufacturers Bösendorfer constructs instruments concentrating on the use of spruce. More than 80% of this wood, ideal for instruments, can be found in Bösendorfer pianos. 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. For outstanding richness of tone colour and our legendary pure and brilliant sound. This complex construction is part of the Viennese tradition of piano making.

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. Our Austrian spruce has to be grown at a minimum of 800 meters (2,600 ft) above sea level guaranteeing a very dense and regular grain structure. Harvested in winter, when the sap is at its lowest, it is subsequently quarter sawn for parallel grain. 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.

All bass strings are spun in our unique Bösendorfer way. A steel core string is the basis for 1 or 2 layers of copper. The carefully spun strings are a substantial element of the warm and sonorous Bösendorfer bass.

Bösendorfer Grands are not just an object of investment but of value that will last more than one generation. Our skilled Bösendorfer Artisans reveal the inner beauty of the Bösendorfer sound, unique in colour, dynamics and expression. Perfected throughout and passed on to inspire generations. It takes the dedication of our Bösendorfer Artisans up to a year to build your Bösendorfer Grand. A personal touch that you will sense the moment you play. Austrian quality, Viennese soul.

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

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 tensions of the forging process are released allowing the frame to remain relaxed under 20 tons of string tension. Pure stability.
