I suppose the North Coast has a few...? Does Ed = still do this sort of thing? =20 David I. ----- Original Message -----=20 From: Ryan Sowers=20 To: Pianotech=20 Sent: Friday, August 27, 2004 6:45 PM Subject: How much friction?

Light is light, either in weight or because of low=20 friction. =20 Andre, I have to entirely disagree on this point in particular, for 2 = reasons: 1. It sounds like you are saying that increased down weight that = results from increased friction is the same as increasing the down = weight by manipulating the weight of action parts. Lowering friction = will increase the up weight of the key, while decreasing the down weight = at the sometime. Adding friction does the opposite. Adding lead to the front of the key will will decrease the down weight = and decrease the up weight. A very different effect on the touch of the = piano to be sure. You can have actions with equal down weight that feel = very different. Don't forget that inertia plays an important role in the players = perception of the touch. Ed McMorrow's (author of "the Educated Piano") = pianos are a perfect example. People perceive his actions as light but = he gets his down weight toward 60 grams (if I'm remembering properly). = The lower inertia he achieves by drastically removing hammer mass (and = also key leads) produces the sensation of a light touch despite a = 60gram down weight. Interestingly Ed also recommended (in his book) = pinning the hammers a little on the tight side (which goes back to our = previous subject on pinning)! 2. Lacquered hammers have plenty to do with it! There is a strong = connection between voicing and touch perception. A player will many = times perceive an action with soft hammers that require greater velocity = to gain fortissimo tone as heavier than an action with hard, less = resilient hammers. I've had clients be amazed at how I changed the touch = of their piano by only working with the hammers.=20 : =20 Ryan Sowers, RPT Puget Sound Chapter Pianova Piano Service Olympia, WA -------------------------------------------------------------------------= ----- Do you Yahoo!?
