Hi Marc,
Some researchers at the University of Bath actually researched this
matter and the frequency of the trompette is identical to the pitch of
the string that activates it. The timbre is so different that this
pitch correlation isn't clear to the ear, but it is verifiable. So,
basically, rosin and cotton are responsible for getting the chien to
sound and controlling its volume but they do not impact its pitch at
all (at least the do not in a properly working system!). I'm trying to
find the old message (it was in 2002) that explains this and will
repost it when I find it.

Hello,
Although this article gives a good way to comprehend the working of
the chien I have some serious doubts about the 293 times... this is
in no way explained and up to me this frequentie depends from many
factors ...
Weight of the chien, amount of rosin on the wheel and coton on the
string, lengt of the string diameter tension.....
Who has a good explanation for those???
Marc

A few years ago I came across an article in French titled
'Functionnement du chevalet mobile de la vielle à roue' by Pierre
Rebaud, originally published in 1984,which shows the various
forces on the chien which cause it to work. The article says that
the up and down movement of the chien repeats 'approxiamately
293' times a second.
