Thanks, Fred. Admirable attempt to put a difficult  concept into words. 
Five  Lectures has its uses,  eh?



Not just Five Lectures, but also the excellent high speed  videography of 
Stephen Birkett, which makes the theoretical writings visible.  The video he 
posted of the close up of the Wapin pin is particularly vivid,  showing the 
"shivering" of the wire at the pin - the various partials  activating it. 
The bass string videos are also quite helpful for getting the  message that 
this is, indeed, what happens: a wave propagating from the hammer  blow and 
reflecting back and forth.
