@Sound-Advice said in Lifetime quest finally paying off!:
"I am vehemently opposed to the 'common ground argument' of the (EEE) action of the tongue for the upper register combined with the relative jaw motion because:
A. Raising the tongue to the EE position raises the floor of the oral cavity and thus cuts the oral cavity approximately in half.
Result 1: Vibration is inhibited and muffled in the smaller chamber, leaving a smaller, basic sound to be amplified by the instrument.
Result 2: EEE position of tongue prevents cheek muscles from fighting or resisting air column in the mouth cavity because the air column doesn't reach the cheek muscle. Lip tensions therefore become strained.
Result 3: EEE position of tongue causes air leakage through nasal passage, reducing needed compression at the lips (I would say that 100% of the players that articulate EEE leak air through the nose at the peak of their range"...
End quote of Roy Stevens up to that point...
Sound-Advice... This to meee reads as one dimensional reasoning.
Result 1: Vibration is not a function of chamber volume alone. You cannot forget about the pressure wave within the chamber and the ability of the smaller volume to allow pressure to work in favor vibratory support. (Also the MRI video disproves this read)
Result 2: EEE position of tongue and on influence on cheek function, cranial nerve 12 is independent of cranial nerve 5. If you have not had a stroke (maybe this is Roy Stevens problem) the tongue position had no control override of a person's ability to compensate with cranial nerve control. I'm a physician, don't mess with me man when it comes to physiology of the oral cavity.
Result 3: Nose leakage? Really? Another independent neurological control, cranial nerve 10. We, as humans, have counter regulatory control over these strictures to protect for these actions. So to quote Monty Python: I blow my nose at you!
