Inside a Steinway Piano Factory

At the Steinway factory in Astoria, Queens, a piano rim is bent from eighteen layers of maple by six workers in twenty minutes before the adhesive sets. The rim will hold this shape for a century. This single operation encapsulates the approach: handcraft at industrial scale with no concession to speed.

Steinway was founded in 1853 by Heinrich Engelhard Steinweg. The company's one hundred and twenty-eight patents represent the most intensive period of piano innovation in history. The modern concert grand, unchanged since the 1880s, is largely a Steinway invention.

The soundboard is made from Sitka spruce selected for straight grain. Each board is hand-planed to a precise crown. The bridges, transmitting string vibration, are vertically laminated hard maple for maximum rigidity and tonal clarity.

The action contains over fourteen thousand parts in a concert grand. Each is fitted, regulated, and adjusted by hand for identical key response. Voicing the hammers, adjusting felt density with needles, determines tonal character and is the most subjective operation in the process.

Stringing requires approximately two hundred and forty-three strings generating combined tension of twenty tons. Each string is cut to precise length and wound to specific tension. Tuning pins in laminated maple hold position against this force for years.

A complete grand requires approximately twelve months. The factory produces roughly a thousand pianos per year. Each instrument is assigned a serial number traceable to specific craftspeople.
