| | K 2571: The Making of a Steinway Grand" |
 | | The Steinways' masterstroke was to combine the two ideas in a new design, which also included heavier hammers to excite the heavier strings, a subtly improved action to permit control of the heavier hammers, and a repositioning of the bridge from the rear of the soundboard toward the middle. |
 | | To compensate, the height of the keys in a new Steinway rises, gradually and imperceptibly, from the ends to the middle: the middle keys on a model D are one thirty-second of an inch higher than the keys at either end. |
 | | Steinway's solution was the Teflon bushing, a small cylinder of hard white plastic that was virtually impermeable to moisture--too impermeable, as it turned out, for when extreme humidity changed the dimensions of the wooden parts, elongating the holes into which the bushings were set, the Teflon, unlike cloth, did not expand to fill the holes. |
