I would stick with advice from your teacher. It can get confusing when asking people over the internet when it comes down to embouchure issues. We can guess, but without being with you in the same room like your teacher it is just a guess - and there can be various conflicting answers.Sorry I should have said that I have been taking lessons from an accomplished jazz saxophonist. He has just told me that these notes will come and he has me trying them at every new lesson. I suppose I am just trying to get second opinions here for which I am very grateful.
You may well be right. But could well bring more problems with lower notes so I beg to differ.Rather than a softer reed, you may want to try a harder reed. Sometimes when we try to play higher notes our emboucher tightens up closing off the reed completely at the tip. A harder reed would help with that problem.
Concur. Yes, a harder/stiffer reed will keep the player from literally pinching and "shutting down" the reed up top, but will also make the mid to lower range of the horn more difficult, which in this case the player definitely doesn't need that issue thrown in! My personal advice would be to focus on two things: 1. Airstream. Don't back off when you go into the palm keys. It's a natural thing to WANT to do, but don't. 2. Let that airstream work for you and be your friend instead of the enemy. Meaning, IF the airstream is strong, you'll be less likely to start pinching like hell up top (which in my opinion is the major factor you're having a problem with F and F#).You may well be right. But could well bring more problems with lower notes so I beg to differ.
This is what I mean about internet advice...
