I've been playing alto saxophone on and off for 40+ years and I have always used relatively narrow tip openings whether it be for classical or jazz. Today my setup is and S80 C** (0.068") for classical and a Meyer 5 (0.070"). I'm feel really comfortable with these tip openings and I don't really feel the need to change, but I am curious. In prior mouthpiece safaris I've noticed that in general larger opening mouthpieces had more resistance, were more flexible in pitch and allowed me to play louder. My question concerns whether resistance, flexibility and volume are the only things gained when using a more open tip. For instance, all things being equal are larger openings darker? Does giving the reed a little more distance from any baffle on the mouthpiece cause a darker tone?
