The flutist embouchure is truly a miraculous mechanism. With numerous muscle groups controlling size, and motion, it is no wonder there are so many variations of embouchures. There are two main functions of the embouchure: 1) guide the airstream 2) control airflow. Of course there is a fine balance which needs to take place between the lips. Too tight and the tone suffers harmonic richness, too loose and the tone is diffused and unfocused. Here are a few tips that work for me, when I am focusing awareness on my Embouchure Emissions: -Allow teeth to remain open. This creates more space in your mouth and allows a full stream of air to flow into your flute. -Think about applying a bit of tension to the corners of your mouth. If applied correctly, you should have a rounded opening in the center, with relaxed lips to control airflow efficiently. -The more air you supply the flute, the embouchure will work less. Control not only comes from the lips, but can be monitored by the diaphragm. -Use your ears to shape your embouchure, not just your eyes. Yes, we have all been told to study our embouchure in the mirror, but inspire yourself to also use the aural sense as well. I have seen CRAZY embouchure formations, that produce stunningly beautiful sounds. I have also noticed perfect embouchure formations that produce dull, uninteresting sounds. It is all relative, as Einstein taught us! -Experiment with your embouchure, it is fun. You can find some pretty cool sounds it you allow yourself to explore the possibilities. Try it, you may find a position you were not aware of. For a closer look at the mechanics of the embouchure, read the: "Illustrated Method for Flute," by Sheridon Stokes. "
