So it is true........ where the other voices have brain material, basses have "resonance".
I don't think we need to call any of this esoteric. Music well played contributes to our overall well being.
As far as body use goes, that is the major difference between players. The brass in front of us is fairly consistent, but the body structures could not be more different. We have people of all shapes and sizes doing an excellent job in every musical genre, so the stereotyped "optimum players" don't exist.
The human body is subject to many influences when growing up. The kids that start with music earlier are usually brighter (which doesn't always mean better grades....), and even if ossification is not "tunable", the cerebral development will be to great advantage.
When we are young, we just PLAY, without a lot of thought as to why. As we mature, we are able to "tap" more of our bodies resources on purpose.
This allows us to do things to optimize a "resonance" that is complementary to the instrument being played. In the case of the "classical" trumpet player, this would be to open all of the cavities to get the biggest possible "volume" of air behind the lips. The lead trumpet player needs a different set of breathing skills that involve the big breath, but not necessarily the "opening" of all cavities (tongue higher in the oral cavity to increase pressure/speed for instance).
A violin is made of wood and that is "dead" long before it can be turned into a fine instrument. There is the theory that sympathetic vibration improves the instrument. Maybe it is just like a trumpet though, over a period of time, the "tension" built initially into the instrument spreads out more evenly through the instrument..........
Everything affects everything else. That is why it is important to get started today! Every day not playing is a loss!
p.s. Ossification is a term that lacks political correctness in Germany. We (fondly?!) call our east German citizens OSSIs. Naturally the stereotyped OSSI did not only have "positive" traits. Ossification would be the assimilation of those negatives in a WESSI (a citizen of west germany).......... Maybe Mr. Nelson has found the source of "thick-headedness" though.
