Blow the angry sound of the suona with all your strength. Many people have insufficient understanding of the importance of correct embouchure in suona playing, and lack of understanding and mastery of correct embouchure. Therefore, problems of one kind or another inevitably occur during the playing process. For example, some people blow with cheeks, loose corners of mouth, and rough pronunciation. Some use the method of inflating the gums, which causes the airflow to be dispersed and wastes energy and effort. Some have lips that are too drawn in, tight lip muscles, unpleasant sound, and poor image and expression. In some cases, the lips are spread over a large area of ??the front and middle, and the lips are tightly pressed against the Qi card, causing the sound to be pronounced but not beautiful, loose but not soft, and bright but not crisp. Incorrect mouth shape will inevitably affect the playing, and may even cause difficulties in pitch control and intensity changes, and the contrast between strong and weak amplitudes and timbres will not be obvious. Therefore, the melody played can only be music, not pleasant sounds.
