First, posture
The principle of holding flute accords with human nature. Generally, the flute is held in both hands, the left hand is on the top and the right hand is on the bottom. In ancient times, the south pipe was just the opposite. It's okay to practice flute alone in class, but it has something to do with learning eight-hole flute or playing flute at the same time. It is more convenient to have the same habits in a band.
Because the bottom hole of the eight-hole flute is slightly sideways, it is necessary to re-open the hole when changing hands, and the flute blows horizontally, which has left and right problems. According to the principle that the finger is the easiest to cover the sound hole, the hand should be slightly tilted upward, and the lowest hole should be covered with the finger surface, and then upward. The higher the finger, the closer it is to the hole of the middle finger, which is helpful to the flexibility of pressing the hole. Playing the big flute also helps.
In order to maintain smooth ventilation, the body should keep the waist straight, whether sitting or standing or playing slowly, so as to facilitate the natural and smooth breathing and ventilation. If you are sitting, don't lie flat on the back of the chair, cross your feet, and be sure to sit in the chair in the front third, so as to make your body naturally vertical, not too tight, and just stand upright easily.
Relax your shoulders, too, and it's okay to talk to music. Don't raise your shoulders, adding unnecessary load to your body. Fingers press the flute, and arms naturally hang to both sides. The flute forms an included angle of about 45 degrees with the body. If the south pipe is slightly inclined at 45 degrees, the south pipe flute is called a phoenix flute, and the piper's arms are like its phoenix wings.
Second, take a deep breath.
Playing the flute is the first way to breathe, because improper ventilation will affect your health. According to folklore, it is possible to play the flute and vomit blood. If the method is wrong, but also melancholy personality and love to the flute, the flute will continue to stop, which will be a chronic damage to health for a long time.
Most people breathe through the lungs in the chest. Playing flute or other wind instruments, including singing, requires practicing breathing with the abdomen. Chest breathing ability is limited, playing flute is easy to fatigue and dizziness. On the one hand, there will be a feeling of insufficient gas, and it will also damage the lungs.
Abdominal breathing is the first way to play flute, that is, deep breathing and abdominal breathing are the first way, supplemented by simultaneous use of chest and abdomen. Generally, the lower abdomen is the breathing space, and the necessary Changle sentence paragraphs need to be used at the same time.
Abdominal breathing is used for meditation or practice. In the practice of blowing-blowing, you can practice breathing in front of the mirror. You can see that the phenomenon of fog is the breath coming out of the abdomen. You are proficient in breathing. When practicing blowing-blowing, you should blow the drum sound first, and then put the end of the flute close to the mirror. After playing the flute, the mirror will also have fog, that is, the breath coming out of the abdomen.
It is the author's personal experience to check whether his method is correct with a mirror, which can be described as simple and true. When the breath in the abdomen can be exhaled, it is simple and natural to inhale, because the space there has been squeezed out, and as soon as it is inhaled, it will go deep into the abdomen, so it is also one of the methods to have the correct exhalation method first.
To ensure that abdominal breathing is natural, you can ask others to pay attention to the physical changes when blowing. When blowing, the stomach will slowly disappear, and when inhaling, the abdomen will protrude, not just the chest.
As for inhaling through the nose or mouth, if you practice flute cultivation, inhaling through the nose is the best way. If you are playing or recording, you need to practice breathing with your nose and mouth at the same time to quickly reduce the sound of breathing.
Most people have abnormal guttural sounds when they play the flute. Some people can play the erhuqin even if they don't play the wind instrument, but their bodies are not completely relaxed. It will take some time to adjust their strike strength, and the extra tension will be eliminated as much as possible, just like a class with high shoulders.
Third, tone.
The key influence of Dong Xiao's timbre lies in the melody, and the control of melody and breath is the most important and basic skill of playing, and the skills of playing can also be seen from this, because there are many skills of controlling melody and breath.
For example, the control of strong and weak tones, the change of flute timbre, and even cyclic ventilation are all related to tunes. Personally, I think that in tune control, each flute needs to go through an adaptation period to achieve mastery. In experience, every flute has an adaptation period, especially if it is not played for a while, it takes about ten minutes to half an hour to start playing.
Extended data
Tang-style mouthpiece needs to have a flat outlet and a flatter and thinner treble, so that the air pressure is strong, instead of blowing with greater force, and the lips are controlled to be elastic. When playing bass, the lower lip is backward, so that the upper lip is relatively forward, the breeze is loose and the flute sound is low.
The tune of playing Nanguan Xiao belongs to the elliptical gas beam, especially when it is high-pitched, it can be low-volume high-pitched or high-volume high-pitched, which is completely controlled by the tune.
The scale of flute playing is about three octaves, and the sound hole is only one octave. The change of octave lies in the tightness of tone and the strength of breath. Basically, the high notes need strong breath, the tone is important, the low notes should be loose and the tone should be weak. According to this principle, if you need more strength to play high notes, you actually narrow your tune and increase the airflow, instead of maintaining the original tune and increasing your strength to play, which will be very tiring and the method is not right.
Although Dong Xiao's scales are divided into five holes, six holes, seven holes and eight holes, they are also divided into traditional and modern rhythms. Japanese shakuhachi and China musical Xiao are already twelve-tone scales, and only Nanguan Xiao keeps the traditional mode.
