The most common way to pronounce a clarinet is to touch the top of the whistle with the tip of the tongue; stick the tip of the tongue to the lower tooth, and then arch the tongue to touch the whistle. Either way, there are several common principles: the chin and throat must remain fixed; the mouth and mouth remain unchanged; and the air flow and pressure remain constant. During practice, try holding your breath and using your tongue to do a single puff, followed by a "sudden" sound from the airflow. When the player blows through the space of the Reed and the mouthpiece, and with the appropriate pressure on the lower lip, the thin Reed tip produces vibration, which makes the air column in the clarinet begin to vibrate, thus giving out a soft tone. Note that the mouth type must be correct, the corner of the mouth as hard as possible to both sides (the thicker the whistle needs the greater the mouth), a smile mouth type. Usually should practice long tone, try to keep the sound stable, at the same time strengthen the practice of spitting, pay attention to the adjustment and use of breath.
