Re: Problems with High G
You seem to be having a very re-occurring problem with tenors. The high G is usually a very touchy note. You mentioned that you never had this problem when younger. Please do not take what i am about to say as a reproach since I have never heard you play . Your problem is easily fixed ,,,but a knowledge of how a conical bore actually works is of benefit . If you wish to know more about this email me I will be glad to explain this a bit more, but you need not understand the theory to apply the solution.
You might not believe this but you probably have had this problem all along and compensated for it with extra bite. I also suspect that as you move up during scales that the color and timbre of the notes change especially when you pass through a bridge key. This is a no no as,, (musicality is dependant on eveness of timbre and volume),,,,, and it's the first sign of more fundemental problems.
If this is the case then your real problem is lack of air pressure. Saxophone is a tricky instrument to play well. The air going into the horn needs to enter at incredible speed ( we are not talking quantity here). The air going in should go in because the air pressure in the horn is lower than that in the lungs . The result is that as the two pressures are trying to balance each other out and air enters into the horn on its own and extremely fast.
When you can properly compress the air in your lungs by using your diaphragm (it feels like a sustained push downwards towards your pelvis, while these latter muscles prevent a ballooning outward) the now pressured air will be expulsed ,,,on its own,,,no need to push air out ,, at a high speed. The result of this will be more efficient acoustics .
You will notice-- eveness of timbre,,less adjustment of embouchure required ,,,,more reeds are playable,,,constant volume ,,,,,,better pitch ,,,,better and cleaner attacks,,,,, leaks will be more evident,,,high notes will sound lower pitch than they really are because they will be more full ,,,,,,palm notes will no longer be shrilly ,,,,,and more ..
one caution-- always make adjustments with air pressure not bite
