Steinway & Sons Model O Grand Piano

Braces

3 solid spruce with a volume of 1,253 cu. in. (20,528 cm³); Spruce provides tensile strength with less weight. Maple dowels fasten braces to rim producing a single homogenous foundation upon which is built the entire tonal component. The Steinway & Sons iron wedge anchors brace ends securely to crossblock assuring permanent rim posture.

Dampers

Horizontal-cut premium wool for effective dampening with maple heads for endurance.

Keys

European spruce, individually weighed-off. Chip-proof, stain-resistant coverings for naturals; slip-proof, abraded ebonized sharps. Durable Linden wood buttons reinforce keys over balance rail, permitting maximum tonal power with every strike. Longest key: 19" (48.3 cm).

Keybed

Made from planks of quarter-sawn spruce. Horizontal and vertical birch planks present a vented system for humidity escapement. Crowned and reverse-crowned action frame gives a snug fit, intensifies key movement and prevents “slapping” during heavy playing. Large maple dowel ends provide a solid mount for adjustable brass touch-regulating screws. Thickness: 1¾" (4.45 cm).

Heavy, solid brass. Soft, sustaining, and full sostenuto.
