Are you trying to learn how to weigh off keys in a particular piano, or are you doing some sort of historical manufacturer key leading protocol? What is your interest in pattern leading?

I find it easy to lay out all the Cs one below the other, but this does not show the typical changes in numbers of leads between sections, or where they occur. The difficulty I have found in trying to capture the first and last key of each section is that photos of black keys do not easily show the leads, which have been painted. Also, I'm not sure comparing #26 sharp leading with #27 natural leading is the best/most meaningful. Ideas? Does anything like this already exist someplace? > > Trying to learn about action ratios, inertia, etc. -- that is, from the point of view of what's been done in the past, is common to certain makes, models, periods of manufacture, etc. Thanks in advance for any suggestions. > > Paul Milesi RPT > Washington DC > (202) 246-3136 Cell/Text > paul at pmpiano.com > http://www.pmpiano.com -------------- next part -------------- An HTML attachment was scrubbed...
