Nawwwwwwwwwww. Your skipping rope is just like the speaking length of a piano string. You pluck it or whack it and it vibrates. Period. It vibrates. The length of time it vibrates will vary directly with the solidity/immobility of the speaking length terminations (a cast iron capo bar works better than a hunk of loose rubber). Similar with the soundboard. It vibrates. The more solid/immobile/massive the rim, the less the soundboard can vibrate the rim, and the less energy is lost at the rim. I really don't think there are things zipping back and forth and bouncing off this or that. I do know that it makes for great graphics in four-color brochures. That kind of thinking is consistent with the thinking that bridge wood/laminations need to have the grain oriented a certain way so the sound energy can pass through the bridge from the strings to the soundboard. Don't think so. Terry Farrell > Hi Terry, > > Take a skipping rope. Tie it to a concrete wall or some other massive > object. Put a pound of tension on it. Now "pluck" it.
