When the cucurbit flute is playing, there is a strange sound, so how does it appear? Hulusi performance requires two different ways of using air. One is hard blowing (heavy blowing) and the other is slow blowing (light blowing or flat blowing). When blowing hard, it can produce all the sound hole sounds of the drum tone 5 and above. Slow blow can only sound with a specific pitch when all the sound holes are pressed (and no air leaks), that is, the 3 of the bass. When blowing, there will be an uncertain sound close to the bass 5, and we often inadvertently make such a sound when playing. In the process of playing the cucurbit flute, strange sounds may occur in the following situations.
1. There is a strange sound at the end of the sound when playing the ending phrase of the long note. The solution: maintain the pressure in the mouth, and quickly open the mouth to exhale the remaining air, so as to avoid the strange sound. Requirements: First, the airflow must be spit out in the last second, and the pressure should not be relaxed first, and then the mouth should be opened. Second, the movements should be light and natural, and the mouth should not be too large. After opening the mouth and exhaling, keep the mouth shape and inhale quickly (breathing).
2. When the phrase begins, it is easy to bring out a strange sound before it is pronounced. The reason is that the oral pressure at the beginning is not enough, which is similar to slow blowing, so it will bring out the strange sound. The solution: Each phrase begins with a spit (a "spit" or "snap" tongue movement).
3. In the middle of the phrase, especially when playing double vomit, it is easy to have obvious strange sounds, and some of them seriously affect the performance of the music. At this time, neither of the above two methods can be solved. Let’s analyze the main reason. Tone is generally divided into continuous vomit and intermittent vomit. In the slower music process, these two methods are commonly used, but some friends don’t pay much attention to it. The distinction between the two can be easily confused when used. During continuous exhalation, the breath is continuously exhaled, and the sounds are distinguished by the tongue (each sound has a sound head), but the time value is relatively full, and there is no knee between the sound and the sound; , and the pressure in the body, including the pressure in the abdominal cavity, chest cavity, and oral cavity, is always maintained, that is, the so-called sound is broken. When some friends play double vomit, when they have not fully mastered continuous vomit and broken vomit, they often use the broken vomit method to play double vomit naturally and unnaturally. In this way, the air flow is broken at the end of each note When it is turned on and the pressure is not enough, a strange sound is produced. Another part of my friends makes strange noises even when the breath and pressure are not very good when the single vomit ("bitter" or "grid" or "brother") is not well mastered. By practicing more "bitter" , so that it is very close to the "spit" sound in terms of strength, speed, timbre, volume, etc. At this time, the strange sound will naturally disappear during the performance. In addition to the above two situations, there are also strange sounds because the reeds of the instrument are hard and difficult to control. At this time, the best way is to change to a more professional or suitable instrument for your own situation.
When solving the third situation, the most important thing is that the airflow must be kept in the state of exhalation, and it must not be tolerated. The airflow velocity cannot be too slow, and the oral pressure must be maintained.
When there is a strange sound in the cucurbit flute during the performance, you can find the cause and solve it according to the above method. Try to avoid the appearance of strange sounds to make playing more comfortable.
