Cy,
I suppose, but I don't know what good it would do him. Did you read the 
article? Did it tell you anything Del hasn't already covered in his Journal 
articles, and that hasn't been discussed on the list? What did you learn 
from it that was new or, better yet, useful? I saw one equation, a fourth 
order differential equation "describing" the transverse vibration of piano 
strings. Do you have at hand, any of the information necessary to plug into 
those equation variables to work it? I sure don't, nor would I know where 
to start looking for them if I wanted to. Do you have any idea what the 
derived number would mean if the equation was solved? I sure don't, and the 
article didn't give me a clue, except that the results are said to be 
similar to the example of the time history graph of a real piano frequency 
spectrum of a single note shown in figure 1. What practical application 
that may have, I have no idea.

This article is, in all fairness, installment #1, and the first one of any 
series tends to be pretty general. I'm looking forward to something more 
practically informative and useful in future installments. This could prove 
to be a very interesting series.
