Re: Saxophone Tuning?
I'm a sax student on the university level. I would suggest getting a saxophone master class book, and working on your embouchure. I would suggest Saxophone Master Class by Michael E. Hester www.vcisinc.com/saxophonemusic.htm#Master%20Classes
Other than that, try a smaller reed, about a 3. Work on playing with a little more pressure in your high register. Another solution could be working with less pressure on your low register, and pushing the mouthpiece in. Either you have too little pressure, or you're biting a little too much. Those are just a few suggestions. Plus, any given saxophone is going to have a few small tuning discrepancies.
