Hi David,

I believe the difference between a two-keyed clarinet and a chalumeau can
be best explained by a chapter of Jack Brymer's book on the historical
development of the instrument. Basically, Johann Denner began
experimenting and produced "improved chalumeaux" round abouts of 1790.
These evolved into clarinets by 1800 by which time he had added a speaker
key (and the a key on the front) to
extend the compass by allowing the instrument to overblow. Note that it
should not be called an octave key, since it produces a twelfth above the
fundamental. The first clarinets had a theoretical (not dreadfully
practical!) range from f to d3.

The only reason this is so fresh in my mind is that I have been rekeying
my dissertation and I typed this section last weekend!
