Playing Skills of Hulusi: Throttle, Mouth and Mouth
1. throttle
The space where the breath passes between the upper and lower lips during finger blowing. The damper can be large or small, and it changes with the pitch of the sound. Decrease the damper when playing low notes and widen the damper when playing high notes. The position of the damper should not be left or right, it should be in the middle of the lips, and the upper and lower lips should contain the blow hole of the cucurbit silk. This depends on the production of the blow hole of the cucurbit silk to determine whether the upper lip is slightly more prominent than the lower lip (generally Under normal circumstances, the upper and lower lips should be the same).
2. tone of voice
The breath that blows through the damper is the breath of the mouth. The tone of the mouth is divided into priorities. The choice of the tone can control the strength and air consumption of the air. Because the cucurbit flute is a vertical blowing type reed pipe coupled vibration instrument, it is mainly composed of a reed and a bamboo pipe to couple and vibrate. When playing, hold the blow hole with your mouth, and use the method of super blowing, the air flow passes through the air box (gourd), makes the reed tongue part of the reed vibrate, and stimulates the resonance of the air column in the tube to make the sound. Genes are generally not used when playing (tub sound blown by the slow blow method). The speed change of the throttle is controlled by the activities of the high abdomen, diaphragm and thoracic cavity, and the three parties should be well controlled.
3. mouth
The size of the mouth is determined according to the size of the damper and the priority of the tone. Be sure to pay attention to the close coordination between the mouth and the wind at the door. Although the tone of voice and the strength of the mouth can be divided into priorities when playing the cucurbit flute, but because the method of playing the cucurbit flute is over-blown, the priority is relative and has a limit, that is to say, it changes within a certain range. The reason is limited by its own conditions (the sound range is too narrow).
