Hi Joel

I confirm that the note indeed has a strong second partial as do all the 
harmonica notes I've ever looked in spectrum. That, along with the geometry 
of the other partials is what makes a harp sound the way it does. And 
varying the harmonic content of notes is something we do all the time. 
Remember, we all make those impossible 4th partials of overblows (called 
screeches) on our way to getting them under control 8^)

When I finally hear you "get the missing note" -  i.e., reduce the 
fundamental and/or increase the required partials - I'll be very excited. 
And sure, messing with a reed physically is OK - as long as the reed can 
still do 'double duty'. So keep at it.
Though, I do have trouble imagining how some chordal/vamp soup up around 
that part of the harp on the draw plane can bubble up a lost melody note - 
is that even a chord you'd want under a major seventh melody note ?? i don't 
know ...

Transcribe! is a great program and I use it every day. And anyone who has it 
can use it to see the partial in question. But you surely know that bump on 
the graph doesn't occur in isolation. The question is ... can you use it (or 
any other program or spectral display) to show the melody note you say you 
are producing. Remember, you're the one who added "Scientific" to this 
thread.

Cheers,
Staggerin' Jim
