Would you be willing to share the essence of Mr. Jacobs' lecture?

I always try to be accurate when quoting Mr. Jacobs; I wrote down almost everything he said in the lessons immediately after I was finished, but over the years I can't find all of the little notebooks I used. I put them in places where I won't loose them (you know, those places you forget about because they are so "special"). So here goes:
He told me the York tubas were designed to be played with a funnel shaped mouthpiece. The Holton is a copy of the York and so you should play a funnel cup mouthpiece.
He believed that bowl shaped mouthpieces produce a darker sound (than a funnel cup) and the large tuba (e.g., a Holton) needed more overtones to carry the sound out over the rest of the orchestra. Therefore, the funnel shaped cup was necessary.
He said the horn performed better with funnel shape cups and talked about airflow within the mouthpiece, made some drawings (which I have - somewhere) depicting what happened with a bowl-shape vs. a funnel shape.
This aspect would seem to apply to the mouthpiece only and not be affected by which tuba was being used, so, according to this logic, a funnel shape mouthpiece should always perform better than a bowl shaped mouthpiece at all times. I don't believe that even Mr. Jacobs would ascribe to my "logical" deduction.
There was a lot of additional upbraiding which I will forgo but it dealt with "what were you thinking of to forget such a fundamental fact of playing, etc., etc, but it's OK, here's a Helleberg you can use in the lesson."
Two things from the perspective of 2008 (twenty something years later):
1.
Almost everyone used smaller diameter mouthpieces at that time.
- I was playing a Giardinelli Helleberg in those days, the diameter was probably 31.5mm.
I never played his original Helleberg, but the Canadian Brass copy has a 31.75 mm diameter.
The Helleberg 7B is 31.5mm according to my info.
The Conn 2's of that period were cut on the original (from the 30's) Helleberg mandrel. About 31.5mm.
The "original" (70's version) Conn Helleberg copy is at least 32.5mm and was considered a very large mouthpiece at that time.
Many of the mouthpieces being sold and played today are 33 and 33.5 mm diameters. That is a HUGE difference.
One way to play the Yorks successfully (but
not all of the York copies are good enough to respond to this) is to use a smaller diameter mouthpiece (Helleberg) and let the horn work for you. This would be against the grain of today's players who depend on massive amounts of air being pushed through the aperture causing a wide aplitude of vibration (speaking of the embouchure itself here) resulting in a much louder sound than Mr. Jacobs used regularly. Such loud playing may be one of the contributing factors in the rise of the number of people who are displaying nuero-muscular problems.
Ask yourself, if Jacobs was so successful on a small diameter Helleberg why don't any of today's players use that mouthpiece? My answer? Things change; his sound was so individualistic that it is not understood by some (conductors) and his style and approach to playing is fading.
His sound carried over the orchestra at any dynamic. Most of today's tubists play louder when they want to be heard, Jake depended on color to be heard. His lung capacity, his physiology, would not allow him to compete athletically... but his artistry allowed him to excell individually.
2.
Mr. Jacobs was not technically inclined about tuba design. His interests were in the psycho-neuro-muscular phenomenon area, the biological processes.
His opinion was that .750 was the perfect bore size for a tuba. It makes sense, the Yorks (both the 4/4 and the 6/4) were .750 bore - that works great, it must be perfect. If Pop Johnson liked it, so did he. Rarely did he address technical issues about tuba construction in a lesson or in conversation that I have heard.
With exceptions: Leadpipes and he liked that the York & Holton's had a larger 4th valve tuning slide because it helped give the horn an "organ-like tone in the low register." I asked him about the ports in the 4th valve ports being smaller and the tubing immediately after the 4th slide being smaller and he said it didn't matter. It was a Pop Johnson design.
Heck, who can blame him.
