The Model O features three solid spruce braces, which measure 1,050 cubic inches in volume (17,202 cm3). These reinforcements provide high tensile strength without adding strenuous weight to the instrument. A seamless foundation is created by fastening the spruce braces to the piano’s rim and cross-block with maple dowels, on which the tonal component is built. Long-lasting rim posture is ensured by affixing the Steinway & Sons iron wedge anchor brace ends to the cross-block.
Overstrung; combination agraffe; front and rear duplex.

Steinway piano keys are produced only from carefully selected European spruce. Each key is precisely weighed-off. The white naturals are coated to be resistant to staining and chipping. Black flat and sharp keys are abraded to be slip-proof and ebonised for rich colour. Peak tonal power is assured with each touch by durable Linden wood buttons reinforcing the keys over the balance rail. The longest key measures 19″ (48.3 cm).
The keybed is formed from quarter-sawn spruce planks. Birch planks are cut horizontally and vertically to provide a vented system that allows moisture to escape. Enjoy heavy playing with a crowned and reverse-crowned action frame that ensures a tight fit, preventing ‘slapping’ and allowing for intensified key movement. A sturdy mount for adjustable brass touch-regulating screws is offered by the large maple down ends. Thickness: 1¾” (4.45 cm).
Finished from durable, solid brass. Ideal for soft, sustained and full sostenuto play.
