We each built/ made, a violin and viola and did a spectral analysis on the
sound boards. We had to prove the difference in tone and volume not just with
our lugs but on paper. I also made 7 smallpipe chanters out of totally
different woods and showed the different tonal and harmonic qualities of each.
Its true when you remove the keybox the the air movement quadruples. Covering
all the holes made little or no difference.
I did not actually play the gurdy when I did this ,but I did manage to
borrow a Boudet and made a bit of a noise ( I think that is the correct term ).
The harmonics on the screen were quite incredible.

I am no mathematician but I fail to see how is possible to disprove a
theoretical negative. Of course, on the face of it, the vibrations sold be
stifled by the weight of the keybox, but then a lot of energy is put in, which
is perhaps a combination of string weight and tension. And then there is a
whacking big slot in the soundboard but it still works, so there must be
something wrong with negative theories. How did you prove this other than
demonstrating?

After watching people playing for the past 40 years and playing for the past
4 years I have never seen a string breaking due to chien use. There is not
excessive pressure by the string on the chien. As you tension the string it
lifts the chien off the body, minutely and when you rotate the handle in an
irregular motion it vibrates on the inlay on the face of the body. I studied
music technology as an adult student and one of the things I helped prove was
that a hurdy gurdy theoretically should not work. Happily I was able to prove
the theory wrong.

Kevin,
So if the dog moves up and down the string, won't that eventually
break the string, in the contact area where it rubs?
