I finally decided to move to the Tenor sax, which was my original quest. I started with the clarinet, then the alto and now rented a tenor sax. I was concerned that it would be too difficult. I was pleasantly surprised to find that it played very much like the alto, meaning I could run the entire chromatic scale. The problem I am having is that I am getting a sort of "flutter" mainly in the lower octave. Even when trying to play long tones I could not get the steady sound. Since this is a refurbished rental low end, I don't know if the problem is me or with the Sax. I have tried different levels of breath force and embouchure. Ideas?
