To play the common vibrato of cucurbit flute, vibrate the high-pitched tone one to two times quickly; when playing the virtual finger vibrato, swing your fingers at the lower two degrees of the vibrato to achieve the vibrato effect, generally press the full hole but not strictly, you can also Shake your fingers just above the hole. To blow abdominal vibrato, the vibration of the lower abdomen should be used to control the airflow to produce a vibrato effect, and the fingers should not move.
If you want to play vibrato with cucurbit silk, you should also pay attention to the following issues:
1. The cucurbit vibrato refers to a sound that has a relationship between a sound and the second or third interval above the sound, which is rapidly and evenly alternated to produce a unique auditory effect. It should be noted that the tremolo has a very accurate interval relationship, which is related to the vibration of air, Refers to the vibrato that differs in the magnitude of the vibrato.
2. When practicing vibrato, under the premise of constant breath, the fingers should open and close the upper sound hole evenly, slowly and powerfully to train the elasticity and agility of the fingers. After a period of time (about one to three months), the fingers move relatively freely, quickly and powerfully, and then gradually speed up (open and close the sound hole three to four times per beat).
3. When practicing vibrato, you should also be careful not to be in a hurry, you need a process of skillfully controlling the movement of your fingers, and you must pay attention to the uniformity, coherence and persistence of your fingers. Haste is not enough. During vibrato training, the shoulders, forearms, wrists and fingers are required to be in a relaxed state, and any tension in any link will affect the quality of the vibrato.
