Qi tremolo is a musical effect obtained by relying on the natural control of the abdominal muscles and the diaphragm to make the air flow in a uniform and regular fluctuation. . Gas tremolo is an important means to make pronunciation beautiful. It has the same effect as the vibrato effect of a stringed instrument and the vibrato effect (referring to very fine pitch fluctuations) produced by a vocal actor when singing.

Air tremolo is often used in some slower and stretched rhythms and long lyrical melodies, it can make music get a natural, relaxed, and melodious singing. It is not only closely related to the expression of emotion, but also makes the sound quality of the instrument produce a round and plump beauty. When practicing gas tremolo, you should firstly avoid deliberately defibrillating the airflow to a large extent, and it is even more taboo to use chest breathing or use the throat knot to debounce the airflow, so that the music produces a non-crying and non-laughing effect. The correct method is to use abdominal breathing to exhale the air naturally and peacefully to achieve a stretched melody effect. The main source of the vibration of the flute is the rapid relaxation of the abdomen. To make it easier for you to understand, let me use an analogy. When we are talking, if it is more pleasant, then we will laugh. When we are laughing, the air flow of continuous laughter is the air flow of the air vibration we want. . When playing the flute, I consciously alternate between the light and the accent, which will get better over time.

Generally speaking, when practicing, it is like this, the light tone is long, and the heavy tone is short. Then gradually, shorten the light sound until it is the same length as the heavy sound, and the air tremolo is perfected. Don't rely on the change of the mouth shape to achieve the gas shock effect, it will be very awkward. When playing some more stretched melodies, air tremors are often used. It can make the music show the same changes as "water waves", enhance the expressive power of the music, so that the audience can enjoy the beauty. Qi should sink downward, and the lower abdomen should be exerted. Qi tremors are generally widely used when playing long notes. It is recovered and released in a small, elastic and uniform range of the abdomen, so that the blown sound has the feeling of "singing". Singing, we can continuously make the sound of "Aah ah..." to find the feeling, and then practice on the flute. The practice is to start slowly, pay attention to the uniformity of the sound, and gradually speed up on the basis of uniformity. When playing mid-bass, the airflow is slowed down and the tone is relatively relaxed. When playing high-pitched, the airflow is accelerated, the damper should be relatively concentrated, and the lower abdomen should be properly exerted. When playing a long note, first blow out the note decisively, and then start to vibrate faintly from a slow pace, and gradually accelerate to meet the required requirements. When playing the vibrating note, pay attention to the fact that the gas cannot be raised with the back and forth vibration of the lower abdomen. It must always be Keep it around the waist, and at the same time, keep the air flowing smoothly, and maintain a certain strength at the corners of the mouth. The speed of the air tremolo is determined by the speed of the music, neither too fast nor too slow. When playing some more stretched melodies, the air tremolo is often used. It can make the music show changes like water waves, enhance the expressive power of the music, so that the audience can enjoy the beauty.
