Tremolo is a relatively important skill in the performance of cucurbit flute. Many pieces of music have tremolo performance requirements. Today we will talk about how to play cucurbit tremolo.

tremolo

Finger tremolo is also called virtual finger tremolo, and it is also called perforated vibrato. It is generally marked with the symbol ~~~. Finger tremolo is an important skill in the performance of cucurbit flute and Bawu, and is most used in the music of the Dai nationality. The method is very simple. As the name suggests, the sound is played across the holes, that is, in the second hole below the position of the original sound, the fingers are smoothly flapped to produce an effect similar to string vibrato. Take the full press for 5. as an example, when playing 3, use the ring finger to fan the 1 sound hole, when playing 2, fan the 7. sound hole and so on.

Although the practice of finger tremolo is simple, it takes a lot of work to practice it well. It is mainly the practice of fingers. It must be beautiful in appearance, uniform in speed, fast or slow, control freely, and the sound should be mellow. Do not leave traces, do this for the best effect of virtual tremolo. Most players like to close the sound hole every time the virtual finger tremolo vibrates. I don’t think the effect is the best. It will make the sound vibrate a lot, and it will feel like a kind of noise without a sense of beauty. , you can try not to close the entire sound hole, but only close one-third of the sound hole when the finger is fanned, what effect will appear.

gas tremolo

Abdominal vibrato, also known as abdominal vibrato, is generally identified by the symbol ~~~. It is a water-like sound wave formed by the regular alternation of strength and weakness of breath. It is obtained by the elastic vibration of abdominal muscles and diaphragm. But it is not as rich in style as finger tremolo. Some friends may say that wind instruments such as cucurbit flute are too difficult to learn. When you play for a while, you will feel dizzy, and sometimes golden flowers will appear in front of your eyes. In fact, this is caused by the use of incorrect breathing methods. The correct breathing method for playing the cucurbit flute is to maintain the correct way of holding the cucurbit flute, naturally open the chest and abdomen, inhale the breath, and then pass the diaphragm (between the chest and the abdominal cavity of the human body, there is a thin The muscle tissue that is shaped like a hat, medically called the diaphragm, because it is placed between the chest and abdomen, called the "diaphragm") and the force around the waist to release the air pressure, which is the power of breath .

The sonic effect makes the progression of the melody full of singing. In practical application, the frequency of sound waves is divided into fast and slow. When playing music with a simple and elegant style, the frequency of sound waves should be slow and the amplitude of vibration should be large, similar to the feeling of singing. When playing energetic and passionate music, the frequency of the sound wave should be slightly faster and the amplitude should be uniform, similar to the effect of singing. In addition, a good sound wave effect should be uniform in frequency and amplitude, and the speed should be controlled freely according to the needs of the music.

When practicing, you must first rely on the correct shape of the lips. In addition, it is very important for the abdomen to control the breath. First, the breath is controlled by the abdomen, and then the breath is gradually and regularly discharged out through the control of the abdomen. When practicing slowly, you should feel the strength of your abdomen to push your breath out in bursts. We can also control our abdominals through the speed of the metronome to achieve an even vibrato. Air tremolo is widely used in music and is even a sign of a player's playing style. So pay attention. In addition, when practicing air tremolo, you should pay attention to breath relaxation and connection. The amplitude of the vibration between the sounds should be uniform, not too dense, the pitch should not change, the intensity should be average, and the sound quality should not be stiff. These all depend on the control of the breath. If you can do this, then your air vibration will be successful !
