Developing an embouchure for a great sound on soprano, alto, tenor and bari. Just buzz on the mouthpiece only. How much mouthpiece do I use? Look at the side of the mouthpiece and look for the part where the reed stops touching the mouthpiece and you see some space between the mouthpiece and reed. Your mouth should go this far on the mouthpiece. As mentioned above top teeth on top and fold a little bit of the bottom lip over the bottom teeth using this as a cushion only don’t bite. All your pressure and support should be on your top teeth. Never bite up because it will cause response problems down low and cause the palm keys to be very sharp. Also you want to focus the corners of the mouth in and have a circular formation of the embouchure to add for support and control. The sound you want to make on the alto mouthpiece is a concert A or F# on your sax. If you have the right embouchure you should sound a concert A. If it is low you need to be more firm. If you are high then drop the jaw and focus the corners in to bring the pitch down. For soprano you want to think same approach, but with a more compact embouchure. You will want to match a concert C or use your palm key D on soprano. With tenor use a concert G and with Bari use a Concert D. The larger the instrument the more relaxed embouchure. When playing on the mouthpiece use plenty of air support because the mouthpiece is more resistent then the sax. If you do everything correctly you will find that the sax responds better for you.
