I understood the relaxed bit but then you lost me 😀I used to say to students that playing a saxophone should be as close as possible to standing upright and relaxed with good posture without a sax. Essentially bend the elbows and raise forearms keeping everything relaxed. Add a saxophone.
Weight is supported via a sling from the neck, or something around the shoulders. Not the thumbs. They can play a large part though - the lower thumb can push away from the body in a horizontal plane. The left (upper) thumb does similar. They act as stabilisers and work with the sling or harness hook providing a 3-point holder/stabiliser.
Can a wind instrument be played in a completely relaxed way? I'm thinking neck. Blowing to any sort of volume I've certainly never achieved this, though the rest of me is fairly relaxed - shoulders down etc. Of course, some people are just bigger too, with big shoulders and necks - so Paul Desmond for example is going to have a tougher time physiologically playing a tenor sax than Clarence Clemons or Andy Snitzer. It does weigh 3.6kg...
Some people play with the horn further away from the body - meaning that the sling is more slack and the lower thumb is pushing away from the body more. Difference? The angle of mouthpiece into the mouth, and consequently the airflow into the mouthpiece. More angle of mouthpiece will possibly also mean more pressure on reed due to "crowbar" effect if lower jaw is kept "in place". This also depends upon the angle of the head too - towards downwards will mean less pressure.
Compare Paul Desmond to Eric Marienthal. Not sure that there is much difference between the two, unless perhaps you go from one extreme to the other extreme, and even then...
Edit: I have long had problems with my neck after playing. I did have two "minor" whiplash injuries in my 20's. They have certainly had a marked effect - though not so much when I was a "gym guy" and also not so much when constantly playing.
But talking about posture my teacher did say that mine was good, I just need to keep an eye on it
I asked Courtney if you was to give me one bit of advice what would it be and he said play in front of a mirror as someone else on here also said to me to do.
