	It may have its fundamental at one frequency, but all wavelengths 
corresponding to the equation 
	lambda=1/i or  Lambda being the wavelength, and i being all 
integers. 1 is the original wavelength of the frequency the body is tuned 
to.  This means that all of those frequencies (fundamentals) will vibrate  
the entire harp (sympathetically) also. Unfortunately, I don't have to do 
the calculation to tell that the frequencies pointed to in Winslows post or
the Harp Handbook will not all be fundamentals of the tuned body, and hence I 
can't believe these harps won't have odd volume shifts.  Bonking the comb 
and hearing a pling instead of a thunk just tells me "We did what we said 
we would do, now we just have to see what we did does."
