We seek to rediscover the art of the piano as the composer heard it on the instruments of the time;  to collect and study the instruments themselves, conserving many for history, and performing on many, so we might rediscover history’s magic.  We exhibit and curate instruments, tell the great stories of piano and society, and study the history of the piano, its technology and its builders.

Steinway Vertical #15225 Rosewood - “Double-Iron” Frame (Patent Resonator) 

Broadwood Square 8
Steinway 15225
P1000080

The bolts throughout the perimeter of the plate were meant to compress the soundboard, or to maintain support for the soundboard crown as the perimeter might shrink in size.  The vertical piano effectively implemented this “Patent Resonator” concept for the entire perimeter of the soundboard, unlike the production grands, which only compressed at the belly rail or fhe front line of the soundboard.

This use of iron as a cage-like structure to support the perimeter compression of the soundboard was used throughout nearly all verticals built from 1866-1872.

Steinway 15225 Plate support for pinblock

Another innovation was the support of the pinblock by the plate extension of the plate.  .

Steinway 15225 Leg

Legs on these early Steinway verticals were similar to the rococo grand piano leg designs
