Resonance Case Principle
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.
