This quote from "Pianos and their Makers" puts in a nutshell what I describe as the Gradient Zone concept of voicing: "The art in hammer making has ever been to obtain a solid, firm foundation, graduating in softness and elasticity toward the top surface, which latter has to be silky and elastic in order to produce a mild, soft tone for pianissimo playing, but with sufficient resistace back of it to permit the hard blow of fortissimo playing." - Alfred Dolge 1911 I find it difficult to imagine a more succinct way of saying it. My hat is ever off to Alfred Dolge. If any of you are not familiar with the man and his work I strongly recommended reading up on him, especially the 1980 biography by Eleanor Franz. David C.
