Very similar in principle to a violin, the whole body, not just the soundboard, supports sound formation. The core of the piano rim consists of a 10 mm quarter-sawn piece that is specially grooved by experienced 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 and delivers an outstanding richness of tone colour. This complex construction is part of the Viennese tradition of piano making.
Individual Stringing
Each string is individually attached with a handmade loop. Over time this improves tuning stability and is particularly service friendly.
Unique Bass Strings
All bass strings are spun in the unique Bösendorfer way. A steel core string is the basis for 1 or two layers of copper and the carefully spun strings are a substantial element of the warm and sonorous Bösendorfer bass.
Independent Capo d’Astro
Bösendorfer is the only piano manufacturer that applies a detachable and independent Capo d’Astro in the upper register. This is how they assure an utmost precise adjustment in the upper register guaranteeing the original Bösendorfer Sound for generations.
Open Pinblock
An open pinblock consists 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.
