What mouth type playing flute     Playing the flute is a great role with the tongue, and is closely related to the quality of timbre. Usually when playing, some players do not know that the tongue can change the direction and angle of the tone and airflow. The average player, only know to stick the lips together, breath concentration, rely on the lips to control the Angle of the sound, and ignore the use of the tongue. The airflow angle they blew out was only a direct friction, which was not fully vibrated at all. The blowing timbre is very straight, stiff, rough, with no sense of mellow and resonance. Some players even have air - leaking sounds. If you make a good use of the tongue, you will get a very pleasant, magnetic flute timbre. The tip of the tongue should be placed at the bottom of the lower tooth at the beginning, the middle of the tongue to arc, then the tongue to the jaw, in the direction of the tongue to the jaw, the middle depression, to form a small flow channel. The air flow blows into the sharp edge of the flute hole, and the upper jaw and tongue must be squeezed together to have a sense of resistance and air pressure, which makes the air flow passage smaller, and the inner diameter of the channel is only the thickness of chopsticks. Air pressure plays a key role in the timbre of the flute. If there is no air pressure inside the mouth, it is impossible to make the tone concentrated, firm, full, and penetrating. Just like the principle of tap, when open tap, because its pressure is not very big, so the injection is not very far. If the pipe diameter is reduced, the pressure increases and the injection is far away. The same is true when playing the flute. When the tongue stands, against the palate, gather into a small passage, producing a great pressure of air flow, increasing the flow speed of the flow, blowing the tone is both concentrated and full, and penetrating and metallic sound. Pay attention to the middle of the tongue to form a small channel like the thick of chopsticks.  If the tongue does not stand up to form a small channel, it cannot form an air pressure. Like the principle of a gun, the barrel of the pistol is shorter and has a short range; while the barrel of a long gun has a long range. When gathering the tongue into a channel, the air pressure increases, and its flow rate is both fast and concentrated.
