Oh dear, I didn't see the ... (dot dot dot). Thanks for pointing this
out Bruce.

And as Hans so graciously notes, the tone quality is indeed affected by
stuffing the hand in the bell. Careful tuning will help to reduce the
amount of hand motion needed (if any). One could argue whether moving
one's hand makes the sound better or worse. It would be interesting to
see how a variety of hornists tune/play their different horns but that
would most likely be a phd thesis in itself - maybe several.
For me, on my 8d, the hand slightly farther in the bell translates into
easier playing in the high register and also better sounding (at least
to my ear). But then I am a rank amateur and I did spend several years
in the Navy standing next to an emergency diesel on a submarine so I
really don't have much of an ear left. ; )
Good question Valerie. It will be good to hear what others have to say.

Valerie,
Indeed, at least for a Conn 8d, putting the hand further in the
bell
does increase the amplitude of the resonant peaks in the higher
register. John Backus did some research back in the seventies
using a
Conn 8d on this. I would suspect other horns behave the same way
to
varying degrees though perhaps with newer horns ways have been
found to
raise the impedance of the higher harmonics through changing the
acoustic shape of the horn so less hand motion is needed on newer
horns. Having played exclusively on older horns - Alexanders,
Conns and
a smattering of Bessons etc, I can't really say much about newer
model
horns. Perhaps others have someting to say about this. A good
discussion and some graphs of this effect that is available online
can
be found at
online.physics.uiuc.edu/courses/phys193/NSF.../adamwatts_thesis.pdf.
I don't agree with quite everything that is said in the thesis but
in
general what is said is reasonably valid.

Wendell, have you found the use of hand in bell for centering upper
register
notes more important with certain horn types? I saw a master class
taught
by Gail Williams. The student playing an 8D and was struggling with
the
upper register. When Gail had her "use more hand" in the bell the
upper
notes popped right out. The difference was so dramatic, it looked
almost
"staged" but I doubt it was. I haven't personally found such a
dramatic
difference in hand use for centering the upper register of the horns
I've
played (Yamaha 667, Holton 179, Holton Merker with medium, and
Holton Merker
with large bell throat).
What say you?
