It's an easy thing to say, but where is the evidence that establishes
that the C clarinets were "*darker*" than today's B-flat clarinet?
How many Beethoven era clarinets were measured for cutoff frequency?
Where is this study published? Who is in support of it?

I offer the suggestion that the main sonic characteristics of a
clarinet derive from the length of the tube and the cylindrical nature
of the bore. Other factors that have an uncertain influence on the
character of the sound include the media (boxwood/blackwood), and
perhaps even the mouthpiece.

Finally, I note with great pleasure you statement that all of this
important scientific data does not tell use what that "nice dark
sound" is or how I, as a player, can get that thing; i.e., what
do I do with my mouth, body, nose, teeth, belly, etc. to improve
the "darkness" quality?

Are you really sure that darker (=higher cutoff freqency_ and brighter
(= lower cutoff frequency) has been conclusively proven? Or is that
there is a difference in character of sound between high and low
cutoff frequencies, but that difference does not fall in the realm
of what is generally referred to as "dark" and "bright" whatever
they mean in the first place?
