Yhath,
I agree with CJ that long tones are great for developing tone. In fact I think the ultimate in tone development comes from doing the overtone exercises as discussed in Sigurd Rascher's "Top Tones for Saxophone"
These exercises should probably be viewed as a long term project but they are effective.
Try playing your low Bb and without changing the fingering sound the overtones F and then the middle Bb. It may sound terrible the first few tries but after working with it for a while it strengthens the embochure and helps you develop sound imagination.
That is an advanced concept for sure.
That Top Tones book gives a pretty good explanation.
cheers,
Don Manuel
