"If reducing metal at the rivet end makes the reed less stiff, and 
raising the pitch requires that stiffness be increased, then why does 
reducing metal at the rivet end make the pitch go up, which it certainly 
does?"

Reducing metal at the rivet end of the reed makes the reed more flexible 
and drops the pitch because a more flexible reed has a longer swing so 
the frequency decreases.  Stiffening the reed towards the root would 
have an opposite effect, the interval of the oscillation would decrease 
and the pitch would rise.

An amazing website that has withstood the test of time.  I also checked 
www.PatMissin.com and did not see anything on this topic but my search 
was not extensive.  fjm
