In the process of playing suona, the intensity of the sound will be changed according to the needs. Beginners often cannot deal with it very freely, so what should we do? Today, I will share with you a simple experience.

Crescendo blowing method When we change from weak blowing to strong blowing, we first need the player to find the correct feeling and method of weak blowing: after the breath has settled, the airflow should be thin and slow, the whistle should be small, and the mouth should be small. It should be small but not lose the sense of expansion, and the lips should contain less reeds, so that the vibration area of the reeds will change from large to small. In order to maintain the sense of expansion of the cavity during weak blowing, the larynx and pharynx must be opened, the airflow must reach the upper palate, and the sound in the resonance cavity must be concentrated into a "spot". When we need to increase the volume, first of all To strengthen the strength of the inspiratory muscles at the same time, the expiratory muscles begin to gradually increase the strength. The slit of the mouth gradually increases, the whistle gradually widens, and the gradually increasing airflow always rushes to the soft and hard palate; the mandible is gradually pulled down, and the oral cavity is also from small to large, but the control in the oral cavity must be maintained. In the process of completing this series of requirements, it feels like the sound gradually expands from a line to a powerful sound that fills the cavity.

Of course, these are just macro-control concepts for the crescendo of the sound, but in practice, due to the differences in the high, middle, and low parts of suonas, suonas of different tunes, different sound areas on the same suona, and different Reeds, different playing styles, etc., make complex changes in the position of the resonance tube, cavity and force position, and it is difficult to express clearly in language, so we still use the usual suona upper and lower positions. Comparing different playing styles to achieve a macro grasp of the playing methods of the crescendo of the suona sound.
