Hi. I play tenor saxophone since many years now and I still have a lot of problem to have a freeblowing sound. Actually it is not that my sound is not good but it is not the sound I want. I do not have a freeblowing sound especially in the medium register which is too dark with really not enought projection or brightness. It is as if I was struggling to produce a sound that is not fit to the natural sound of my instrument. Sometimes I wonder If Dexter Gordon, John coltrane and the other tenor sax giants played on a tenor sax. What I search is a light sound that I could really decide by myself. Currently I have the impression that the instrument and my setup dictate my sound. And that affect a lot my playing because as I have not a freeblowing sound my articulation and so on are dictate by the sound that is produced by the instrument. For information I use a selmer mark VII with an Otto link NY metal 8 and rico royal reed 3. I have the feeling that the opening of my mouthpiece or maybe its too large chamber are the reason for that dark sound. But Dexter Gordon and even Coltrane had a large chamber mouthpiece and they also had a great projection. All the tips you could give me will be great.
