A person who says that his cheeks will become bigger because of wind music must have never really touched wind music, or his playing posture is wrong, especially for saxophone, a woodwind instrument. When playing, it requires the joint action of oral muscles, upper lip muscles and lower lip muscles to tightly wrap the flute head. In this process, if the masseter muscle (commonly known as cheek) is too hard, the strength of the mouth will be transmitted to the back of the mouth, and the flute head will not be contained. If the masseter muscle is not hard, the mouth will lose its strength completely, and not only will the flute head fall off from the mouth, but even if it does not fall off, it will definitely leak! However, learning the "circular breathing method" still needs to drum your cheeks, but this method is rarely used! It doesn't matter! Therefore, the most important thing for saxophone beginners at first is to train the strength and durability of the mouth muscles! Otherwise there will be technical bottlenecks in the future! My senior also plays saxophone. She is very thin, and her face has never been deformed by playing wind music!
