Steinway & Sons Model A Acoustic Grand Piano

Steinway & Sons Model A — professional parlor grand acoustic piano

Steinway & Sons Model A is a parlor grand model with a length of 188 cm. It is designed to bring the tonal philosophy of a large concert grand into a more compact size. The Model A is a balanced choice for spacious living areas, chamber music halls, conservatory rooms, professional teaching studios, and high-quality recording environments. Its sound character is distinguished by a natural transition between warm bass, articulate mid-range, and clear, melodic treble.

Diaphragmatic Soundboard and resonance

The soundboard is crafted from select, quarter-sawn Sitka spruce. In the patented Diaphragmatic Soundboard construction, the thickness tapers from approximately 8 mm in the center to 5 mm at the edges. The double-crowned profile and the three solid spruce braces, hand-fitted to the soundboard, facilitate efficient string energy transfer, note sustain, and a balanced tone across all registers.

Rim and acoustic system

The Model A's continuous bent rim is crafted from 16 layers of hard rock maple and is approximately 2¾ inches thick. This sturdy construction minimizes energy loss in the rim, directing it to the soundboard. The overstrung scale, combined agraffe system, and front and rear duplex scales add a rich overtone structure to the fundamental tone. High-tensile Swedish steel treble strings and pure copper-wound bass strings are used; the longest string is 141 cm.

Touch and action

The European spruce keys are individually weighted and balanced; the longest key is 48.3 cm. Premium wool felt hammers and a precisely regulated action provide delicate control in soft pianissimo passages, agility in rapid repetitions, and a full response in climaxes. Vertically laminated hardwood bridges are topped with a solid maple cap. The seven-ply Hexagrip pinblock and high-strength cast iron plate ensure long-term structural and tuning stability.
