Bosendorfer

Bosendorfer, founded in 1828, is one of the oldest piano companies in the world. It is also among the most revered and exclusive, hand making only a few hundred pianos per year. Bosendorfer's tonal definition, power and singing qualities have made it the choice of uncompromising musicians for almost two centuries. Bosendorfer's quality and performance is unsurpassed, and has inspired generations of musicians that have created our shared musical heritage.

The magic of Bösendorfer

All our grands share the same fundamental features.

Resonance case principle

Bild2 ResonanzkastenFor outstanding richness of tone colour and our legendary pure and inspiring sound. This complex construction is part of the Viennese tradition of piano making. The whole body, not just the soundboard, supports sound formation, similar in principle to a violin. We use  Austrian spruce tonewood, the ideal sonic material, which constitutes over 80% of the wood in every Bösendorfer grand piano- this is the highest percentage of any manufacturer. 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 formed 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 gives the whole instrument an unparalleled resonance.

Our Austrian spruce has to be  grown at a minimum of 800 meters above sea level  (for very close annual rings), and harvested only in the winter, when the sap is at its lowest ; it is subsequently quarter sawn for parallel grain.  Our timber is air dried naturally for up to 5 years, and further dried for up to an additional 6 months  before use, to ensure maximum sound quality and stability.

Handmade in Austria

Handmade in Austria by our skilled craftsmen with painstaking attention to detail and using only the finest materials - our team of master craftsmen, technicians and craftsmen have incomparable experience; it can take over one year for the final instrument to be completed.

One of our early successes was the ability of our grand pianos to withstand Franz Liszt's virtuoso playing technique. Our unique construction still has the same ability to meet the toughest demands of professional pianists and Institutions. Privately owned instruments are cherished and passed down from one generation to the next.

Independent Capo d’astro

Single stringing

Each string is individually attached with a handmade loop. Over time this improves tuning stability and is particularly service friendly.

Open pinblock

This allows firmer and more secure seating of the tuning pins which in turn gives a technician more direct control. We make our own pinblocks using 3 layers of 7mm quarter sawn maple glued cross-grained to each other.This is then glued to a baseboard of laminated red beech, and the top is capped with a 1.5 mm thick walnut veneer.

Anything is possible- the world of finishes and designs.

In principal any RAL colour and any veneer can be used. A colour pattern will be made and agreed prior to the start of production; and the direction of grain, if relevant, will be determined.

Hand spun bass strings

We make all our bass strings in our own unique way - it is no surprise that our bass is so legendary.

Sand cast frames (made in Austria)

We use this traditional casting method which is widely considered to produce the best tonal results. Our frames are stored in the open air for c. 6 months to eliminate all internal stresses.

Bild12 290imperialExtra notes

2 concert models in our range come with additional bass notes–our  225 model has in total  92 notes and our 290 has 97 ( a full additional octave)  rather than the standard 88.  Certain works, e.g. by Bartók, Busoni and Ravel, can only be performed on them. This may be a luxury,but these extra bass strings guarantee additional harmonic resonance throughout the whole instrument, adding an almost orchestral dimension for which these instruments are renowned.

Which instrument should you choose?

There is no easy answer- all our instruments are hand-made, so every one is unique. Our advice would be just try them out, then select the instrument that gives you the most pleasure. But be warned! It may not be the instrument that you had in mind. No matter; bigger or smaller, we always find room for those we love.
